BEST 45H0L3J626 – Frequently Asked Questions

1) Does the BEST 45H privacy lock use a key, and does it come with a core?
It doesn't. The 45H L privacy function is a non-keyed lock, thumbturn inside with no cylinder in the lever trim. Note that the 45H body carries an SFIC prep less core, so if you need a keyed or key-override opening you want a keyed 45H function instead, and you'll be buying the small format interchangeable core separately either way.
2) Will the 45H mortise lock latch into the strike already in my frame?
The latchbolt on the 45H is solid stainless with a 3/4 inch throw, and the privacy function also carries a stainless deadbolt with a 1 inch throw. So the frame needs a strike prepped for both a latch and a deadbolt, on a standard ANSI mortise strike location. An existing passage or latch-only strike won't have the deadbolt pocket, and you'll need to swap the strike or extend the cutout.
3) Do I have to specify hand when ordering a BEST 45H mortise lock?
For the lock body, no. The latch is field reversible and rotates 180 degrees without opening the case, and the auxiliary bolt and cylinder retainer are non-handed. That's useful if you're stocking a few spares for a building and don't know which openings they'll land on. Lever style is still a selection you make, across seven options including Curved with Return, Curved without Return, Gull Wing, Contour with Angle Return, and the 3, 4 and 12 designs.
4) Is the BEST 45H a Grade 1 lock, and is that grade good enough for a school or hospital restroom?
The 45H meets ANSI A156.13, Series 1000, Grade 1 for Operation and Strength with a Grade 2 Security rating. For a privacy opening, restroom, exam room, dorm bath, that's the relevant part: Grade 1 operational and strength is what carries the cycle load in a high traffic building, and security grade matters less on a non-keyed door. If a spec calls for full Grade 1 including security, the 47H series is the one rated Grade 1 for Operational, Strength and Security.
5) I need a Grade 1 privacy mortise lock but not BEST. What else is there?
Two direct alternatives on the same function. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. The Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset with a door thickness range of 1-3/4 to 2 inches, so it covers slightly thicker doors than a standard-config 45H without a special order. Where BEST separates is the SFIC prep, if the rest of your building is on BEST cores you want to stay in the 45H family even on the non-keyed openings so the trim and prep match.
6) The door does not need to lock at all, just latch. What replaces a BEST 45H privacy mortise lock?
For a door that only needs to latch, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating. The BEST 45H is a privacy function that throws a 1 inch deadbolt from the inside; a passage lock has no locking function at all.
7) The opening needs a key from the outside, so privacy is wrong. What BEST-comparable mortise lock should I order instead?
For a keyed opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch. The BEST 45H is non-keyed, so none of the escutcheon trims on it accept an outside key.
8) For a behavioral health or patient room, is the BEST 45H the right mortise lock or should I look at anti-ligature trim?
For ligature-resistant openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function, the MRX-A-01 is a passage function ligature resistant arch trim mortise lockset in satin stainless steel, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant. The BEST 45H uses conventional lever and knob trim, though it is offered in 626AM and 630AM UltraShield antimicrobial finishes for healthcare and elderly care use.
9) The door is only 1-5/8 inches thick. Can I still use a BEST 45H mortise lock?
The BEST 45H standard configuration is built for 1-3/4 inch doors, with a thick door version for doors up to 5 inches. For thinner leaves, the Alarm Lock DL2700CR and DL3500CR Trilogy electronic mortise locks are both Grade 1 classroom function listed for doors 1-5/8 to 1-7/8 inches, and the DL4500 Series Grade 1 electronic mortise deadbolt covers the same 1-5/8 to 1-7/8 inch range with a privacy keypad.
10) Can I use a Baldwin 6301 mortise lock body in the same door prep as a BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body, in both knob by knob and lever by lever versions, uses a 2-1/2 inch backset and is listed for doors 1-3/4 inches and over, and the Baldwin 6310 entry/storeroom bodies are also 2-1/2 inch backset. The BEST 45H is a 2-3/4 inch backset, so the lock case sits at a different distance from the door edge and the prep is not shared.
11) Is there an antimicrobial finish option for BEST mortise lock trim in a healthcare building?
Two: 626AM, satin chrome with the UltraShield antimicrobial coating, and 630AM, satin stainless with the same coating. BEST recommends UltraShield where cleanliness drives the spec, hospital and elderly care, education, food service, transportation and hospitality. If you're standardizing a patient wing and want the finish to match your existing satin chrome or satin stainless hardware, the AM versions land on the same 626 and 630 numbers.
12) What is the difference between the escutcheon trim options on the BEST 45H, J, M and N?
Three escutcheon choices. J is a wrought escutcheon, M is forged, and N is forged with a concealed cylinder. On a privacy lock N's concealed cylinder look is largely cosmetic since the function is non-keyed, so J or M is the usual pick, with M's forged plate being the heavier plate of the two. Whichever you choose, keep it consistent across a floor if you want the trim to read the same on every door.
13) Should I order a privacy mortise lock or a passage lock for a restroom door?
Depends on whether the door needs to lock at all. Privacy, which is what the 45H L function is, gives you an inside thumbturn that throws a bolt, for a single occupancy restroom, exam room or bedroom. If the room is a corridor, closet or a multi-stall restroom that never locks, a passage latch is the right part and it's less to go wrong, the Schlage PM010 and the Falcon MA101 are both Grade 1 heavy duty mortise passage locks. For a room that needs to stay locked and be opened with a key, neither one works and you want a keyed storeroom or office function.
14) Will a BEST 45H mortise lock hold up on a high traffic restroom door?
That's what the construction is for. The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, with four case cover screws at the corners and an interlocking armored front and cover at the latch. The hub runs on roller bearings, and the trim carries a lever return spring, which is the part that stops lever droop after a few hundred thousand pulls on a door people shoulder through.
15) Does the BEST 45H privacy lock meet accessibility requirements for lever operation?
BEST states the design and operation of its mortise lock meets the intent of ANSI A117.1 section 404.2.6, the accessible door hardware provision. Practically, that means specifying a lever rather than the round knob, style 4 is the knob in the range, and the Curved, Contour and Gull Wing levers are the accessible choices.
16) What is the difference between the BEST 45H with escutcheon trim and the Hager 3810E and 3810S passage mortise locks?
The Hager 3810E is a 3800 Series Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset, and the 3810S is the same passage lock with rose trim instead; both are listed for doors 1-3/4 to 2-1/2 inches thick. The BEST 45H shares the 2-3/4 inch backset and is supplied with escutcheon trim in wrought, forged, or forged concealed cylinder, but it is a privacy function rather than passage, so it locks from inside the room.
17) What is the difference between the BEST 45H privacy mortise lock and a classroom mortise lock like the Corbin Russwin ML2003?
The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors. A classroom function is locked and unlocked by key from the corridor side; the BEST 45H is a non-keyed privacy function operated from inside the room.
18) Is the Schlage CO-100 privacy mortise lock an alternative to a BEST 45H?
The Schlage CO-100-MS-40-KP is a standalone electronic mortise lock in the CO Series with a privacy function and keypad reader, Grade 1, heavy duty, for 1-3/4 inch doors. It covers the same privacy function but is credential-driven at a keypad, where the BEST 45H is a mechanical, non-electronic lock with no reader to enroll or batteries to maintain.
19) I only need a thumbturn or a deadbolt on the door, not a full privacy lockset. What are the options next to a BEST 45H?
If the opening only needs a bolt, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, and the Kaba Ilco 185 Series mortise lock is a deadbolt function with no handing. For the turn piece alone, the Sargent 130KB is a standard mortise thumbturn in the 8200 Series and the 130W is a mortise thumbturn with a round backplate in the 7800 Series. The BEST 45H is a complete privacy lockset with latch, deadbolt, and escutcheon trim on the same 2-3/4 inch backset.
20) Will an Emtek 3102 Memphis mortise entrance lockset work where a BEST 45H privacy lock is specified?
No. The Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan, and 3019 Brisbane mortise entrance locksets are all dummy function, as is the Schlage L0170 half dummy trim. A dummy has no latch and no locking action; the BEST 45H is a working privacy function with a 3/4 inch throw stainless steel latchbolt and a 1 inch throw deadbolt.
21) I need the mortise lock to release on an access control signal. What takes the place of a BEST 45H there?
For access-controlled openings, the Command Access ML190 Series motorized mortise lock is heavy-duty storeroom function with field selectable electrified lock or unlock operation on 24VDC, and the Schlage L9092EU electric lock/unlock outside lever mortise lock is heavy duty corridor function with request to exit and 12/24VDC, for 1-3/4 inch doors. The BEST 45H is a mechanical non-electronic privacy lock with no wiring to the case.
22) Which mortise privacy lock should I standardize on across a dormitory floor that also needs a corridor exit function?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, for the corridor doors. The BEST 45H covers the non-keyed privacy openings inside the suite, with escutcheon trim and a 2-3/4 inch backset, and it is offered across fourteen finishes including 626 satin chrome and 630 satin stainless so the two can be matched visually on the same floor.
23) For a Marks USA 21AC or 22AC ornamental iron door, can I order a BEST 45H instead?
No. The Marks USA 21AC and 22AC entrance double cylinder ornamental iron mortise locks with round knob are listed for 1 inch doors. The BEST 45H standard configuration is built for 1-3/4 inch doors, so a narrow ornamental iron stile is outside what the 45H case is set up for.
24) Do I need a fire rated mortise lock instead of the BEST 45H?
Where the opening carries a fire label, the Falcon MA101 Grade 1 heavy-duty mortise passage lock is fire rated, and the Schlage Electronics LEMD-GRW Grade 1 ENGAGE wireless mortise lock carries a 3 hour rating, as does the LEBMB-ADD mobile-enabled mortise lock at Grade 2. The BEST 45H meets ANSI A156.13 Series 1000 Grade 1 Operation and Strength with Grade 2 Security, and its privacy function is generally used on interior room doors rather than rated corridor openings.
25) Can I get a BEST 45H mortise lock in oil rubbed bronze or matte black to match the rest of my doors?
Fourteen finishes on the 45H, including 613 oxidized satin bronze oil rubbed, 622 matte black, 690 statuary dark bronze, plus bright and satin brass (605, 606), bright and satin bronze (611, 612), bright and satin nickel (618, 619), bright and satin chrome (625, 626), satin stainless (630) and the two antimicrobial versions. Two of them change with age by design: 613 is meant to wear to an antique look, and 690 stays a dark brown over time. If you need every door in a corridor to look identical for the next ten years, pick a plated or coated finish rather than 613.
26) Is the BEST 45H an electronic or access control lock?
No, the 45H is a purely mechanical mortise lock with no electronics and no wiring in the door. If you need credential control on the opening, that's a different product entirely, the Schlage CO-100 is a standalone electronic mortise lock in privacy function with a keypad reader, and the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock. Those need door prep for the reader and trim, which a 45H prep will not cover.
27) Is the Codelocks CL2255 a lighter-duty alternative to the BEST 45H mortise lock?
The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series with a brushed steel finish, rated medium duty. The BEST 45H is a heavy duty commercial mortise lock with a 0.095 inch cold rolled steel case and armored front, so the two are aimed at different traffic levels and the CL2255 is a latch rather than a privacy lockset.
28) Which RFID or credential mortise locksets sit next to the BEST 45H for a Grade 1 heavy duty opening?
The TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and the FME-4000 Series is an electronic intruder classroom mortise lockset with RFID, also Grade 1 heavy duty for 1-3/4 inch doors. The Dormakaba Saffire LX-M is an electronic RFID mortise lockset with BLE at BHMA Grade 2. The BEST 45H matches the heavy duty rating mechanically and is non-electronic, with an SFIC prep less core.
