BEST 45H7UNR15H626 – Frequently Asked Questions

1) Does the 45H mortise lock come with a cylinder or core?
No core is included. The 45H ships with SFIC prep less core, so it is machined for a BEST small format interchangeable core that you supply and key to your system. Budget the core separately. Note that with escutcheon trim you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) to reach ANSI Grade 1 Security, or a 1EK7K4 high security cylinder with sectional trims.
2) Is the BEST 45H handed, or can I reverse it in the field?
Field reversible. The latch rotates 180 degrees to change handing and you don't have to open the case to do it, and the auxiliary bolt is non-handed stainless. That means one lock covers left and right hand openings, which cuts what a locksmith or maintenance shop has to stock on the truck.
3) Will the 45H drop into a standard ANSI mortise prep with a 2-3/4 inch backset?
Yes, the 45H is a 2-3/4 inch backset mortise body, which is the standard commercial mortise backset. If the existing pocket was cut for a 2-3/4 inch backset ANSI mortise lock, the geometry lines up. Confirm the old faceplate cutout against the 8 inch by 1-1/4 inch face and the pocket against the 5-7/8 x 7/8 x 4-1/16 inch case before you pull the old lock.
4) What grade is the BEST 45H mortise lock certified to?
ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, and Grade 2 for Security as shipped. To get Grade 1 Security you have to add a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. If your spec calls for straight Grade 1 across operation, strength and security without that step, the 47H Series carries all three.
5) What do I have to specify when ordering a BEST 45H mortise lock?
Four things beyond the function: door thickness (standard 1-3/4 inch or the thick door build up to 5 inches), finish from the fourteen offered, lever or knob style, and rose size. Trim comes as H (2-3/4 inch flat rose), R (2-3/4 inch concave rose) or S (3-1/2 inch flat rose). Lever choices run from solid tube with or without return, curved with or without return, contour with angle return, gull wing, or a round knob. And remember the core is not included.
6) Will the BEST 45H latch into the strike I already have on the frame?
With a 3/4 inch latchbolt throw and a 1 inch deadbolt throw, the 45H needs a strike with a deadbolt pocket deep enough for a full inch of bolt, not just a latch lip. A plain cylindrical latch strike will not work. BEST publishes the complete strike package specifications for the 45H in the 40H Series heavy duty mortise lock catalog, and the stainless auxiliary bolt is non-handed so it does not constrain strike selection.
7) Our doors are thicker than 1-3/4 inches. Which mortise locks handle that besides the BEST 45H?
The BEST 45H standard configuration is designed for 1-3/4 inch doors, with a thick door configuration available for doors up to 5 inches when thickness is specified at order. Among other mortise locks, the Hager 3810E and 3810S passage locks cover 1-3/4 to 2-1/2 inches, and the Baldwin 6301 and 6301LS entry/apartment mortise bodies are listed for 1-3/4 inches and over on a 2-1/2 inch backset. For anything past 2-1/2 inches the 45H thick door build is the one that reaches.
8) Is a Sargent 4874 mortise deadbolt a substitute for the BEST 45H universal deadbolt function lock?
No. 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 latchbolt and no lever trim. The BEST 45H is a complete mortise lockset with a 3/4 inch latchbolt throw, a 1 inch deadbolt throw, and rose trim in lever and knob styles, and it is a single cylinder keyed lock. The two share a backset but not the door prep or the operation.
9) What is the closest Grade 1 mortise lock to the BEST 45H if the opening needs a storeroom function instead of universal?
The BEST 45H series is built around a universal function with a 1 inch deadbolt throw and a 2-3/4 inch backset, so it is configured at the hub rather than fixed to one function. If you want a lock that arrives dedicated to storeroom duty, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The Cal-Royal is the nearer match on cylinder approach, since the 45H ships with an SFIC prep less core.
10) The BEST 45H is mechanical. What is the equivalent if we need credential or code access on the same mortise prep?
The BEST 45H is a non-electronic mortise lock. For electrified alternatives, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with classroom function and 300 user codes for doors 1-5/8 to 1-7/8 inches thick, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125 kHz proximity reader, mobile-enabled deadbolt with LED, Greenwich trim, right hand, with a 3 hour fire rating. Note the Alarm Lock door thickness range is narrower than the 1-3/4 inch standard the 45H is built for.
11) What mortise lock covers an access control opening where the BEST 45H cannot be electrified?
The BEST 45H is a mechanical lock with no electronic option. For a wired mortise lock on an access control system, the Command Access ML190 is a heavy-duty motorized mortise lock in storeroom function 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 in corridor function, keyed outside, with request to exit, running 12 or 24VDC on 1-3/4 inch doors. Both require power to the door, which the 45H does not.
12) Which BEST 45H finish should I use in a hospital or food service facility?
Go with 626AM satin chrome or 630AM satin stainless, both with the UltraShield antimicrobial protected coating that inhibits bacteria and microbe growth on the hardware surface. BEST recommends it for hospitals, elderly care, education, transportation, food service and hospitality. The other twelve finishes (605, 606, 611, 612, 613, 618, 619, 622, 625, 626, 629, 630, 690) have no antimicrobial coating.
13) Does the BEST 45H meet accessibility requirements for lever operation?
BEST states the design and operation of the 45H mortise lock meets the intent of ANSI A117.1 section 404.2.6, the accessible door hardware provision. Pair that with a lever rather than the round knob option if accessibility is the driver, since knobs require tight grasping and twisting.
14) I need a mortise lock with a deadbolt but want an electronic keypad instead of keys. What are my options?
The 45H is strictly mechanical, no electronics. If you want keypad credentials with a deadbolt, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad, though it is specified for 1-5/8 to 1-7/8 inch doors. The Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with cylinder override but has no deadbolt. For card and mobile credentials, the Schlage LEMD-GRW is a Grade 1 wireless mortise lock with a proximity reader and mobile enabled deadbolt.
15) What is a comparable Grade 1 mortise lock to the BEST 45H from another brand?
Same class, different function sets. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors. Cal-Royal's NM Series covers 1-3/4 inch doors across office/entrance (NM8050), classroom (NM8070), storeroom with an interchangeable core option (NM8080) and privacy with deadbolt (NM8440). Sargent's 7925 is a Grade 1 heavy duty corridor/dormitory mortise lock with rose trim and a single cylinder deadbolt, which is the closest match if you want rose trim plus a deadbolt. The difference is that the 45H's universal function lets you set locked, unlocked or key-locked in the field rather than buying a dedicated function.
16) Do I need a separate deadbolt if I install the BEST 45H?
No. The 45H carries its own 1 inch stainless steel deadbolt in the same case as the 3/4 inch latchbolt, with an armored front wrapping both. If you only need a deadbolt and nothing else on the door, a standalone body like the Sargent 4874 double cylinder mortise deadbolt on a 2-3/4 inch backset does that job instead.
17) Is the BEST 45H tough enough for a high traffic entrance?
It is built for it. The case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance, the hub runs on roller bearings for cycle life, and the one-piece stainless anti-friction latch makes 50 percent more surface contact with the strike. It is classified heavy duty commercial and certified Grade 1 for operation and strength under ANSI A156.13.
18) What should I use instead of the BEST 45H on an opening that needs no key at all?
For a non-keyed mortise opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating in the MA series, and the Hager 3810S is a 3800 series passage mortise lock on a 2-3/4 inch backset with rose trim for doors 1-3/4 to 2-1/2 inches thick. The Hager 3810E is the same passage function with escutcheon trim instead of a rose. The BEST 45H is a keyed single cylinder lock, so none of these carry its deadbolt.
19) We use the BEST 45H with UltraShield in healthcare. What other mortise locks suit behavioral health or patient rooms?
The BEST 45H offers 626AM satin chrome and 630AM satin stainless UltraShield antimicrobial finishes for healthcare and high-cleanliness work. Where the concern is ligature resistance rather than surface coating, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel described as ligature resistant and ADA compliant. All three are passage, so they do not replace the keyed deadbolt operation of the 45H.
20) Is the Schlage L0170 an alternative to the BEST 45H on an inactive leaf?
The Schlage L0170 is half dummy trim, a Grade 1 heavy duty non-keyed mortise lever lock in dummy function for 1-3/4 inch doors in the L series. It provides a pull only, with no latch and no bolt, so it suits an inactive leaf where the BEST 45H would be overkill. The 45H is a keyed single cylinder lock with a 1 inch deadbolt and a 3/4 inch latchbolt, so the two are not interchangeable on an active opening.
21) For a dorm or corridor opening, how does the Sargent 7925 compare with the BEST 45H?
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. The BEST 45H is also a heavy duty commercial mortise lock with rose trim and a single cylinder keyed deadbolt function, offered in flat 2-3/4 inch, concave 2-3/4 inch, and flat 3-1/2 inch roses. The difference is that the 7925 arrives configured for dormitory exit operation, while the 45H universal lock is set with a four-position hub toggle at install for always locked, always unlocked, or locked by key.
22) We need privacy function with a deadbolt for restrooms. What replaces the BEST 45H there?
The BEST 45H is a keyed single cylinder lock, which is not what a restroom or patient bath wants. The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a 3800 series Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick. The Hager matches the 45H backset, so the edge prep transfers.
23) Would a Codelocks CL2255 or a Kaba Ilco 185 work in place of a BEST 45H?
Neither is a like-for-like. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 series with a brushed steel finish, a latch only rather than a lockset with a deadbolt. The Kaba Ilco 185 series is a no-handing mortise lock in deadbolt function. The BEST 45H is a heavy duty commercial mortise lockset combining a 3/4 inch latchbolt with a 1 inch deadbolt on a 2-3/4 inch backset, so it covers both jobs in one case.
24) Can I use an Emtek Brisbane or Memphis mortise lockset where a BEST 45H is specified?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are all dummy function, meaning trim only with no working latch or bolt. The BEST 45H is a commercial keyed mortise lock certified to ANSI A156.13 Series 1000 Grade 1 for operation and strength. If the spec calls for the 45H the Emtek dummies will not satisfy it on any active opening.
25) Will a 3-1/2 inch rose cover the old escutcheon holes on my door?
The S trim option is a 3-1/2 inch flat rose, the largest of the three on the 45H, and it covers more of the door face than the 2-3/4 inch H flat or R concave roses. It will not hide a full escutcheon footprint, though. If the door was previously fitted with a tall escutcheon plate, you generally need escutcheon trim again rather than any rose.
26) Is a Sargent 130KB thumbturn a substitute for the inside trim on a BEST 45H?
No. The Sargent 130KB is a standard duty mortise thumbturn from the 8200 series, and the 130W is a standard duty mortise thumbturn with a round backplate from the 7800 series. Both are trim components sized to their own lock bodies, not to the BEST 45H. The 45H ships as a complete heavy duty mortise lock with rose trim in flat 2-3/4 inch, concave 2-3/4 inch, or flat 3-1/2 inch, and lever styles including solid tube with and without return, round knob, curved, contour with angle return, and gull wing.
