BEST 45H7AB15H626 – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a 1-3/4 inch door?
The 45H standard lock configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. If your openings are thicker, BEST makes a thick door configuration covering doors up to 5 inches, but that thickness has to be specified when the lock is ordered, not adapted later in the field. Backset is 2-3/4 inches, and the faceplate is 8 x 1-1/4 x 1/16 inches.
2) What does the office deadbolt function on a BEST 45H actually do at the door?
Office function on the 45H gives you a keyed outside lever plus a separate 1 inch stainless deadbolt thrown by key or inside turn. Staff can leave the outside lever unlocked during business hours and lock it when they step out, and the deadbolt adds a second, independent throw for securing the room overnight. It's a single cylinder lock, so one keyed cylinder outside. The latchbolt is solid stainless with a 3/4 inch throw and retracts with the inside lever at all times for egress.
3) Does the BEST 45H come with a cylinder or core, and what do I need to order with it?
The 45H ships prepped for a BEST small format interchangeable core but without the core, so you supply the SFIC to match your existing keying. Budget for that separately. Worth knowing on the security side: the lock carries Grade 1 operation and strength but Grade 2 security as supplied, and reaching Grade 1 security means using a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or a 1EK7K4 high security cylinder with sectional trims.
4) Do I have to specify handing when ordering a BEST 45H mortise lock?
Handing isn't a hard ordering decision on the 45H. The latch is field reversible and rotates 180 degrees without opening the case, and the cylinder retainer and auxiliary bolt are non-handed. There's also a four position hub toggle that sets each hub to always locked, always unlocked, or locked by key, again without opening the case. For a property manager stocking spares across a building, that means one lock covers left and right hand openings.
5) What's the difference between the BEST 45H office function and a storeroom or classroom mortise lock?
Office function means the outside lever can be left unlocked for business hours and locked when needed, with a deadbolt on top. Storeroom function keeps the outside lever locked at all times and requires a key every entry, which is what you want on a supply or mechanical room; the Cal-Royal NM8080 and the Accentra 8805FL 8800 Series are Grade 1 storeroom mortise locks. Classroom function locks and unlocks the outside lever by key only with no inside thumbturn, so a room can't be locked from inside by an occupant; the Corbin Russwin ML2003 and Cal-Royal NM8070 cover that. Cal-Royal's NM8050 is the closest like-for-like, a Grade 1 entrance/office mortise lockset for 1-3/4 inch doors.
6) We want mobile credentials on office and apartment doors. What compares to the BEST 45H there?
The Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, Grade 2, with a 3 hour fire rating, for 1-3/4 inch doors. The LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED on Greenwich trim, right hand, also 3 hour fire rated. Both replace the key with a phone or card credential; the BEST 45H is mechanical and keyed. Handing matters on the LEMD-GRW since it is supplied right hand, where the 45H latch is field reversible without opening the case.
7) What is the closest equivalent to the BEST 45H office deadbolt mortise lock from another manufacturer?
The Cal-Royal NM8050 is a heavy duty Grade 1 mortise lockset with the same Entrance/Office function and is built for 1-3/4 inch doors, matching the BEST 45H standard door thickness configuration. Both are Grade 1 mortise bodies for commercial openings where the occupant needs to secure the door from inside and a key retracts the bolt from outside. The main difference to work through is keying: the BEST 45H comes with an SFIC prep less core, so it accepts a small format interchangeable core in an existing BEST keyway, while the NM8050 is supplied with a standard cylinder. If the building is already on an SFIC keying system, that difference decides it.
8) The opening is a classroom, not an office. What mortise lock should be used instead of the 45H office function?
An office deadbolt function lets the occupant lock the door from the inside, which is not what a classroom opening usually calls for. The Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series, also for 1-3/4 inch doors. Either keeps the outside lever key-controlled with the inside lever always free, which is the standard classroom arrangement.
9) We need a storeroom opening where the outside lever is always locked. What replaces the 45H office lock?
Storeroom function keeps the outside lever locked at all times and a key retracts the latch, with no way for an occupant to leave it unlocked. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors offered with an interchangeable core option. The NM8080 interchangeable core option is the closer match if the building keys on the same SFIC system the BEST 45H is prepped for.
10) Does a Baldwin 6301 mortise lock body fit the same door prep as a BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body is a 2-1/2 inch backset, while the BEST 45H is 2-3/4 inch. That quarter inch changes where the cylinder and spindle land relative to the door edge, so the two are not drop-in for each other in an existing mortise pocket. The Baldwin 6301 is offered knob by knob and, as the 6301LS, lever by lever, both for doors 1-3/4 inch and over.
11) We want keypad access instead of a key on this office door. What electronic mortise lock takes the place of a BEST 45H?
The BEST 45H is a mechanical lock with no electronics. For credential access in the same mortise pocket, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes, and the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card mortise lock with back to back readers. The Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad and no deadbolt, using a cylinder override. Note that the DL3500CR is built for doors 1-5/8 inch to 1-7/8 inch, so verify the leaf before specifying it.
12) The door needs to unlock from an access control panel. What mortise lock does that instead of the mechanical 45H?
The BEST 45H is keyed and mechanical, so it cannot be released remotely. The Command Access ML190 Series is a heavy-duty motorized storeroom mortise lock with field selectable fail safe or fail secure operation on 24VDC, and the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, for 1-3/4 inch doors. The Command Access unit lets you set EL or EU in the field; the Schlage is ordered as electrically unlocked with the RX switch included.
13) For a behavioral health or patient room, is the BEST 45H the right mortise lock or is there a ligature resistant option?
For openings that need ligature resistance, the TownSteel MRX-L-01 is a stainless steel Grade 1 heavy duty anti-ligature lever mortise lockset in passage function, and the MRX-A-01 is the satin stainless steel ligature resistant arch trim version, both for 1-3/4 inch doors. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. All three are passage function, so they do not lock; the BEST 45H is a keyed office function lock with conventional lever and knob trim. Where the room needs cleanability rather than ligature resistance, the 45H offers 626AM and 630AM UltraShield antimicrobial finishes.
14) Which is the higher grade choice for a hotel or multi-family opening, the BEST 45H or the Dormakaba Saffire?
They are graded differently. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access, BHMA Grade 2. The BEST 45H is ANSI A156.13 Series 1000 Grade 1 for operation and strength and Grade 2 for security; to reach Grade 1 security it needs a drill resistant core such as 1CD, 1CDP, 1CDF or 1CDX with escutcheon trims, or the 1EK7K4 high security cylinder with sectional trims. The Saffire is the choice where guests carry a card or phone credential; the 45H is the choice where the property runs mechanical keys on an SFIC system.
15) Is a mortise lock like the BEST 45H the right choice, or should I use a cylindrical lockset?
A mortise lock buys you two things a cylindrical lockset can't: an integral deadbolt in the same case, and a heavier case with hub toggles that let each side be set locked, unlocked, or locked by key. The trade is door prep, since the door has to be pocketed rather than just bored. If the doors are already bored for a cylindrical lock and you don't need a deadbolt, something like the Schlage PC Series cylindrical lock is the simpler swap. If the doors are already mortise prepped, the 45H is the direct fit.
16) Which finish should I pick for a BEST 45H in a hospital or school?
For healthcare, elderly care, education, food service and hospitality, BEST offers two antimicrobial options on the 45H: 626AM satin chrome and 630AM satin stainless, both with the UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. Beyond those, the full finish range runs 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed satin bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 630 satin stainless and 690 statuary dark bronze. Note that 613 is meant to wear to an antique appearance over time.
17) What lever and rose options do I have to choose from on a BEST 45H?
Trim is a separate ordering decision from the lock body. Rose choices are H (2-3/4 inch flat), R (2-3/4 inch concave) and S (3-1/2 inch flat), so if you're covering scars from previous hardware the 3-1/2 inch S rose gives you the most coverage. Lever styles run 12 solid tube with no return, 3 solid tube with return, curved with return, curved without return, contour with angle return, gull wing, and a 4 round knob. The lever return spring sits in the trim rather than the case, which is what keeps levers from drooping in high traffic.
18) Does the BEST 45H mortise lock meet ADA requirements for lever operation?
The design and operation of the BEST mortise lock meets the intent of ANSI A117.1 section 404.2.6, the accessibility requirement for door hardware operation. Choose a lever rather than the 4 round knob to keep that, since a round knob requires tight grasping and twisting.
19) Can someone pull the core out of a BEST 45H from the outside?
Two features work against that on the 45H. A cylinder security screw prevents core removal without proper access, and solid machined cylinder rings with a wavy washer resist cylinder wrenching. Security is rated Grade 2 as standard under ANSI A156.13; if a facility spec calls for Grade 1 security, that requires a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or the 1EK7K4 high security cylinder with sectional trim.
20) Is there a simpler mortise lock than the BEST 45H for a door that does not need to be keyed?
Yes. The BEST 45H is a keyed single cylinder lock, so for an opening that only needs the door to latch, a non-keyed body is the simpler buy. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock in the MA Series with field reversible operation and a fire rating. The Hager 3810S is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset, which keeps the same backset and rose trim arrangement the 45H uses.
21) Can a Sargent 4874 mortise deadbolt be used in place of a BEST 45H office lock?
Not as a substitute for the whole opening. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset in the 4870 Series, so it is a bolt only with no latch and no lever operation, and it takes a key on both sides. The BEST 45H combines a latchbolt with lever or knob trim and a deadbolt in one case, keyed single cylinder. The 4874 is what you add to a door that already has a latching device, not what you install alone on an office door people pass through.
22) The opening is a restroom or a bedroom. What mortise lock replaces the office function 45H there?
Office function is keyed from outside, which is not how a privacy opening is meant to work. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. Both give the inside occupant a thumbturn rather than requiring a key outside, which is the arrangement bath and bedroom openings call for.
23) Are the Emtek Brisbane and Memphis mortise entrance locksets substitutes for a BEST 45H?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are all dummy function, meaning they mount as fixed trim with no latch and no locking action. The BEST 45H is a keyed single cylinder working lock with an office deadbolt function. Order an Emtek dummy for an inactive leaf or a false door only; it will not secure or latch an opening.
24) Will a Marks USA 21AC or 22AC ornamental iron mortise lock work on the same door as a BEST 45H?
No. The Marks USA 21AC and 22AC entrance mortise locks are built for 1 inch doors, typically ornamental iron and narrow gate or storefront style leaves, and both are double cylinder with a round knob. The BEST 45H standard configuration is for 1-3/4 inch doors with a thick door version available up to 5 inch, and it is keyed single cylinder. If the leaf is a 1 inch iron section, the 45H case will not fit it.
25) Is a Schlage PC10 an alternative to the BEST 45H mortise lock?
Only if the door prep is changing. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors. Cylindrical means it mounts through a bored hole in the door face, not a mortise pocket cut into the door edge, so it is not interchangeable with the BEST 45H mortise body. On a door already mortised for the 45H, a cylindrical lock leaves the pocket exposed and requires a filler or a new leaf.
26) Is the Codelocks CL2255 a substitute for a BEST 45H on a commercial office door?
They are built to different duty levels. The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series, medium duty, in a brushed steel finish. The BEST 45H is heavy duty and ANSI A156.13 Series 1000 Grade 1 for operation and strength. On a high traffic commercial office the duty difference is the deciding factor; the CL2255 suits lighter-cycle openings where standalone code entry is the priority.
27) What RFID mortise lock covers a classroom opening where the 45H office function is not appropriate?
The TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the FME-4000 Series is the electronic intruder classroom version with RFID, also Grade 1 heavy duty for 1-3/4 inch doors. The FME-4000 adds the intruder function for lockdown from inside the room. Both are credential-read rather than keyed, unlike the mechanical BEST 45H.
28) The Schlage L0170 is described as a Grade 1 mortise lever lock. Can it replace a BEST 45H?
No. The Schlage L0170 is half dummy trim, a non-keyed L Series lever that mounts on one side of the door for 1-3/4 inch leaves. It has no cylinder, no latch and no locking function, so it cannot secure an office opening. The BEST 45H is a keyed single cylinder office deadbolt lock. Similarly, the Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices and belongs on an exit device opening, not as a lock body.
29) Which mortise lock should be used on a Baldwin storeroom opening where the door is 1-3/8 inch thick?
The BEST 45H standard configuration is designed for 1-3/4 inch doors, so a 1-3/8 inch leaf is outside it. The Baldwin 6310 entry/storeroom mortise lock body is a 2-1/2 inch backset unit covering doors 1-3/8 inch and over, offered knob by knob, with the 6310190RRLS as the right hand reverse lever by lever version. Confirm the mortise pocket depth for the 2-1/2 inch backset before ordering, since it differs from the 45H 2-3/4 inch backset.
30) Does the Alarm Lock DL4500 replace a BEST 45H office lock?
Not on its own. The Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, built for doors 1-5/8 inch to 1-7/8 inch, and its function is deadbolt only. The BEST 45H is an office function lock that latches the door and gives lever or knob operation alongside its deadbolt. If the door needs to latch closed as well as bolt, the DL4500 needs a latching device paired with it.
31) What is the difference between the Alarm Lock DL2700CR and the BEST 45H for an exterior classroom door?
The Alarm Lock DL2700CR is a Grade 1 Trilogy T2 electronic mortise lock with classroom function and a weatherproof design, for doors 1-5/8 inch to 1-7/8 inch. The weatherproof build is the reason to pick it on an exterior opening. The BEST 45H is mechanical with office function and a zinc dichromate plated steel case for corrosion protection, standard configuration for 1-3/4 inch doors. Function is the first split here, classroom against office; door thickness is the second, since the DL2700CR range stops at 1-7/8 inch.
32) For a passage opening that needs an escutcheon rather than a rose, what mortise lock is used?
The Hager 3810E is a Grade 1 passage mortise lock with escutcheon on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, and the 3810S is the same 3800 Series passage lock with rose trim and the same backset and thickness range. The escutcheon covers a taller area of the door face than a rose. The BEST 45H shares the 2-3/4 inch backset and is offered in rose trim only, in 2-3/4 inch flat, 2-3/4 inch concave and 3-1/2 inch flat, so where a spec calls for an escutcheon face the 3810E is the direct answer.
33) We need a privacy function electronic lock for a 1-3/4 inch door. How does the Schlage CO-100 compare with the BEST 45H?
The Schlage CO-100 is a standalone electronic mortise lock with privacy function and a keypad reader, Grade 1 heavy duty, for 1-3/4 inch doors. It matches the BEST 45H on Grade 1, heavy duty and 1-3/4 inch door thickness, and splits from it on function and access method: privacy with keypad credentials against office function with a keyed single cylinder on an SFIC prep. Pick the CO-100 where codes are managed at the door and no keys are issued.
34) How durable is the BEST 45H for a high traffic entry that gets hundreds of cycles a day?
Case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, and the lock is certified ANSI A156.13 Series 1000 Grade 1 for operation and strength, the top commercial tier. The one-piece stainless anti-friction latch is oil impregnated and makes 50 percent more surface contact with the strike, and the hub runs on roller bearings for wear resistance. That construction is aimed at heavy duty commercial traffic rather than light residential use.
35) Is a Kaba Ilco 185 Series mortise lock the same kind of product as the BEST 45H?
No. The Kaba Ilco 185 Series is a deadbolt function mortise lock supplied with no handing, so it provides a bolt with no latching or lever operation. The BEST 45H is an office deadbolt function lock combining a keyed latch with lever or knob trim and a deadbolt in a single heavy duty case. Use the 185 where a bolt alone is wanted; use the 45H where the door must latch and be operated by a lever.
36) Is there a mortise lock that runs without wiring or batteries to swap, compared with the BEST 45H?
The Dormakaba PowerPlex P2066 Series is a mortise lock in the PowerPlex 2000 Series, which is the self-powered line generating its own energy from the lever motion rather than running on wired power. The BEST 45H needs no power at all since it is fully mechanical and keyed. The choice is between mechanical keying with SFIC cores on the 45H and code-based access with no wiring runs on the P2066.
37) Are the Sargent 130KB and 130W thumbturns replacements for anything on a BEST 45H?
They are not lock bodies. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series and the 130W is a standard duty mortise thumbturn with a round backplate in the 7800 Series; both are the inside turn piece that operates a deadbolt, sold as trim for their own series. The BEST 45H is a complete heavy duty mortise lock case with its own rose trim in 2-3/4 inch flat, 2-3/4 inch concave and 3-1/2 inch flat. Sargent thumbturns are ordered against Sargent lock bodies, not fitted to a 45H.
