BEST 45H7T3J626 – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a 1-3/4 inch door?
Yes. The standard 45H lock configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. If your openings are thicker, BEST builds a thick-door configuration for doors up to 5 inches, but you have to specify the thickness on the order. The case itself is 5-7/8 x 7/8 x 4-1/16 inches and takes a 2-3/4 inch backset mortise pocket.
2) What does dormitory function mean on a BEST 45H mortise lock, and is it the right function for apartment doors?
Dormitory function on the 45H is a keyed single-cylinder lock with a deadbolt: the key retracts the deadbolt and unlocks the outside lever, and the inside lever always retracts the latch for free egress. That is why it gets specified on student housing, apartment and multi-unit entry doors, hotel guest rooms and patient rooms. If you want an office or storeroom behavior instead, that is a different function code, not this one.
3) Does the BEST 45H come with a core, or do I have to order the SFIC core separately?
It ships prepped for a small format interchangeable core, less core. You supply the BEST SFIC core in your facility's keyway and keying so the lock drops into your existing master key system. Worth knowing on the security side: the 45H is Grade 1 for operation and strength but Grade 2 security as standard. To get Grade 1 security with escutcheon trim you have to use a drill resistant core, 1CD, 1CDP, 1CDF or 1CDX.
4) Is the BEST 45H handed, or can I change the hand in the field?
Handing is not a stocking problem here. The latchbolt rotates 180 degrees to change hand without opening the case, and the cylinder retainer and auxiliary bolt are non-handed. For a property manager buying across a building of left and right hand doors, that means one lock covers both, and a locksmith can flip it on the bench in seconds.
5) Will a BEST 45H latch and bolt into the strike I already have in the frame?
The latchbolt throws 3/4 inch and the deadbolt throws a full 1 inch, both solid stainless steel, off a 2-3/4 inch backset. That is standard ANSI mortise geometry, so it lands in an existing ANSI mortise strike prep. What it will not do is work in a frame cut for a cylindrical lock or a 2-3/8 inch backset, since the mortise pocket has to accept a 5-7/8 x 7/8 x 4-1/16 inch case. Note the deadbolt: if the frame you have was prepped for a latch-only mortise lock, the strike box needs the deadbolt cutout too.
6) What do I have to specify when ordering a BEST 45H dormitory mortise lock?
Four things settle the order. Trim style: J wrought escutcheon, M forged escutcheon, or N forged escutcheon with concealed cylinder. Lever or knob style: 12 solid tube no return, 3 solid tube with return, 4 round knob, contour with angle return, curved with return, curved without return, or gull wing. Finish, from 605 bright brass through 630 satin stainless. And door thickness if the doors are anything other than 1-3/4 inches, up to 5 inches. You also supply the SFIC core, since the lock comes less core.
7) What is the closest equivalent to the BEST 45H dormitory mortise lock from another manufacturer?
The Sargent 7925 is the nearest match. It is a Grade 1 heavy duty mortise lock with a corridor/dormitory function and a single cylinder deadbolt, so it covers the same dormitory-style opening as the BEST 45H, which carries a dormitory lock function and a single cylinder keyed configuration. The main difference is trim: the Sargent 7925 is furnished with rose trim, while the BEST 45H described here uses escutcheon trim in wrought, forged, and forged concealed cylinder styles. If the door already has an escutcheon cutout or the specification calls for a full escutcheon plate, that trim difference is the deciding factor.
8) The opening is a classroom door, not a dorm room. What mortise lock should be used instead of a dormitory function?
Use a classroom function lock rather than the dormitory function the BEST 45H provides. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset from the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch. Both keep the mortise case prep, so the door cutout work is the same class of prep; only the function changes.
9) For a storeroom or mechanical room door, what mortise lock replaces a dormitory function lock?
A storeroom function is the correct swap, since the outside lever stays locked at all times and entry is by key only. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The interchangeable core option on the NM8080 is worth noting for anyone already keying the BEST 45H, which ships with an SFIC prep less core.
10) Is a mortise deadbolt the same thing as a dormitory function mortise lock?
No. A mortise deadbolt has no latch and no lever, so it cannot serve as the latching hardware on the door. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with a privacy keypad. Those are deadbolt-only devices. The BEST 45H is a mortise lock with a dormitory function and keyed single cylinder operation, meaning the lever and latch and the deadbolt are in one case. Ordering a deadbolt against a 45H opening leaves the door without a working latch.
11) Which mortise lock should be used when the door has to be electrically locked or unlocked from an access control panel?
An electrified mortise lock is required; a mechanical dormitory lock cannot be released from a panel. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock with a corridor function, keyed outside, request to exit, running on 12/24VDC for 1-3/4 inch doors. The Command Access ML190 Series is a heavy duty motorized mortise lock with field selectable EL/EU operation and 24VDC power in a storeroom function. The BEST 45H is a mechanical lock with no electronic operation.
12) What faceplate size does the BEST 45H mortise lock use, and does it need beveling for the door edge?
The faceplate measures 8 x 1-1/4 x 1/16 inches in stainless steel, brass or bronze depending on finish. You do not bevel it yourself: the lock face self-adjusts to the proper bevel during installation, and the trim is self-aligning too. On a beveled door edge that saves the fitting step a lot of mortise locks still require.
13) Which BEST 45H finish should I use on hospital or senior living doors?
For patient rooms, elderly care, food service or anywhere cleanliness drives the spec, order the 626AM satin chrome or 630AM satin stainless. Both carry the UltraShield antimicrobial coating, which inhibits growth of bacteria and other microbes on the hardware surface. Everywhere else in the building the plain 626 and 630 match visually, so you can run the AM finish only on the doors that need it without a mismatched look.
14) What is the difference between escutcheon trim and rose trim on a BEST 45H, and does it affect the security rating?
Escutcheon trim is a full-length plate covering the lock body and cylinder; rose trim is a small round plate at the lever with a separate cylinder collar. It matters beyond looks: with escutcheon trims the 45H reaches Grade 1 security only when a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) is fitted, while sectional trims need the 1EK7K4 high security cylinder to get there. Three escutcheon options are built: J wrought, M forged, and N forged with the cylinder concealed behind the plate, which is the one to pick where you want the core out of sight.
15) I want keypad or card access on dorm room doors instead of keys. What should I look at instead of the BEST 45H?
The 45H is purely mechanical, no electronics, so it will not give you audit trail or code changes. For electronic mortise locks on the same door prep, ZenSupply carries the TownSteel FME-2000 Series, a Grade 1 heavy duty RFID mortise lockset for 1-3/4 inch doors, and the Dormakaba E-Plex 2066 Series electronic pushbutton keyless mortise lock. The Schlage CO-100 standalone electronic mortise lock is another Grade 1 heavy duty option for 1-3/4 inch doors. Where a mechanical key system is what the facility runs on, the 45H stays the simpler answer.
16) Is the BEST 45H tough enough for a high traffic dorm or apartment corridor?
Construction is where this one earns its keep on high cycle openings. The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, with four corner case cover screws holding the case together. The armored front wraps both latch and deadbolt for lateral strength, and a roller bearing hub carries the lever action. The latch is solid one-piece stainless with a precision curve for cycle life and 50 percent more contact surface with the strike. It carries ANSI A156.13 Series 1000 Grade 1 for operation and strength.
17) Does the BEST 45H meet ADA requirements for lever operation?
BEST states the design and operation of the mortise lock meets the intent of ANSI A117.1 section 404.2.6, the accessible door hardware provision. Choose a lever rather than the 4 round knob if accessibility is on the drawing, since a knob requires tight grasping and twisting. Lever choices run from solid tube with or without return to curved and gull wing shapes.
18) If I need Grade 1 security and not just Grade 1 strength, is there a better BEST mortise lock than the 45H?
Yes. The 47H Series carries ANSI A156.13 Series 1000 Grade 1 for operational, strength and security outright, with no special core required. The 45H reaches Grade 1 security only when you add a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. On a dormitory or apartment entry where the spec writer called out Grade 1 security flat, the 47H is the cleaner answer.
19) Will a Baldwin 6301 apartment mortise lock swap straight into a BEST 45H prep?
No. The Baldwin 6301 entry/apartment mortise body uses a 2-1/2 inch backset, while the 45H is 2-3/4 inch. Different backset means a different cylinder and lever centerline in the door, so it is not a drop-in either direction without re-prepping the door. If you are replacing Baldwin 6301 bodies and want to stay in the existing mortise pocket, match the 2-1/2 inch backset rather than moving to the 45H.
20) The door does not need to be keyed at all. Is there a simpler mortise lock option?
Yes. If the opening 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 in the MA Series with field reversible operation and a fire rating. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, which matches the 2-3/4 inch backset and escutcheon trim of the BEST 45H while dropping the cylinder. The BEST 45H is a keyed single cylinder lock, so it does more than a passage opening requires.
21) Which mortise locks give keypad or credential access on a dorm or apartment door instead of a key?
Several mortise locks put access control in the lock body. The Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad and cylinder override, no deadbolt. The Schlage Electronics LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office, and apartment functions on 1-3/4 inch doors with a 3 hour fire rating. The Dormakaba E-Plex 2066 Series is an electronic pushbutton keyless mortise lock. The BEST 45H is a mechanical lock with no electronic operation, so any of these is a change in how the door is credentialed, not just a change in part number.
22) A supplier offered a dummy mortise trim as a match for a dormitory mortise lock. Is that a valid substitute?
It is not. Dummy trim is a fixed lever or knob with no operating mechanism behind it, used on inactive leaves and closet faces. The Schlage L0170 is a Grade 1 mortise non-keyed half dummy trim in the L Series for 1-3/4 inch doors, and the Emtek 3102 Memphis and Emtek 3104 Hamilton are dummy mortise entrance locksets. None of them latch, and none accept a cylinder. The BEST 45H is a keyed lock with a dormitory function, so a dummy will not secure the opening.
23) The apartment doors are getting entry hardware with knobs rather than levers. What mortise lock body suits that?
The Baldwin 6301 is an entry/apartment knob by knob mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over, and the same 6301 is offered as a lever by lever body. Note the backset: those Baldwin bodies are 2-1/2 inch, while the BEST 45H uses a 2-3/4 inch backset, so the door prep is not interchangeable between them. The BEST 45H does offer a round knob among its lever styles if the 2-3/4 inch backset prep is what the door already has.
24) For a behavioral health or patient room where ligature resistance is required, what mortise lockset should be specified?
Specify an anti-ligature mortise lockset rather than a standard lever lock. The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset with a passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function in satin stainless steel with ligature resistant arch trim. 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. The BEST 45H is a keyed dormitory function lock with escutcheon lever or knob trim, which is a different trim profile than these ligature resistant designs.
25) For an office door where the lever needs to be locked or unlocked by hand from inside, what mortise lock covers that?
An office or entrance function does that. The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, non-keyed, for doors 1-3/4 inch to 2-1/2 inch. The Hager 3850E shares the escutcheon trim approach and the 2-3/4 inch backset with the BEST 45H; the difference is that it is non-keyed, while the 45H is keyed single cylinder.
26) Which classroom mortise locksets support RFID credentials for a campus card system?
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 an electronic intruder classroom mortise lockset with RFID for the same door thickness and grade. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. The BEST 45H reads no credential; it is a mechanical lock keyed through an SFIC prep supplied less core.
27) Is there a weatherproof or standalone keypad mortise lock for an exterior dormitory entrance?
The Alarm Lock DL2700CR is a Trilogy T2 electronic mortise lock with a classroom function and weatherproof design, Grade 1, for doors 1-5/8 inch to 1-7/8 inch, and the DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and a classroom function over the same door thickness range. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in a privacy function for 1-3/4 inch doors. Check the door thickness first: the Alarm Lock units cover 1-5/8 inch to 1-7/8 inch, while the standard BEST 45H configuration is built for 1-3/4 inch doors with a thick door configuration up to 5 inch.
28) The door is a bathroom or bedroom that only needs privacy. What mortise lock is the right choice there?
A privacy function is the fit. The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch, which matches the 2-3/4 inch backset used by the BEST 45H. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors. Both leave out the cylinder that the keyed 45H requires, so there is no key to issue for a room that only needs to be secured from the inside.
29) A mortise thumbturn was quoted against a dormitory mortise lock order. Will that work?
No. A mortise thumbturn is inside trim that turns a deadbolt, not a lock. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series and the Sargent 130W is a standard duty mortise thumbturn with a round backplate in the 7800 Series. Both are trim pieces. The BEST 45H is a heavy duty mortise lock, so a thumbturn is at most a component on a different opening, never a replacement for the lock itself.
