BEST 45H7T15H626 – Frequently Asked Questions

1) What does the dormitory function on the BEST 45H mortise lock actually do?
The 45H with T dormitory function is a single-cylinder keyed lock with a deadbolt: the outside lever is locked or unlocked by key, and the deadbolt throws 1 inch. The latchbolt has a 3/4 inch throw. It is the function you put on student housing, apartment entries, patient rooms and extended-stay units where the resident controls the deadbolt from inside and staff key the outside lever.
2) Will the BEST 45H mortise lock fit a 1-3/4 inch door?
Yes. The standard 45H configuration is built for 1-3/4 inch doors, which is the usual commercial thickness. For anything thicker, BEST builds a thick-door configuration up to 5 inches, but you have to specify the actual door thickness when you order it. Don't order standard and hope to shim it.
3) Does the lock come with a cylinder, or do I have to supply a core?
It ships with SFIC prep, less core. You supply the small format interchangeable core and keying separately, which is how most facilities handle it so the lock drops into an existing BEST keyway and master key system. Budget for cores on every opening.
4) Is the BEST 45H handed, or can I change handing in the field?
Field reversible. The latch rotates 180 degrees to change hand without opening the case, and the auxiliary bolt is non-handed stainless. That means one lock covers left and right openings, which is why maintenance shops stock it. The armored front also self-adjusts to the door bevel during installation.
5) What ANSI grade is the BEST 45H mortise lock rated to?
ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, Grade 2 for Security. To hit Grade 1 Security you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or the 1EK7K4 high security cylinder with sectional trim. The design also meets the intent of ANSI A117.1 section 404.2.6. If your spec demands Grade 1 security out of the box, the 47H Series carries Grade 1 for Operational, Strength and Security.
6) What is the closest equivalent to a BEST 45H dormitory mortise lock from another manufacturer?
The Sargent 7925 is the nearest match. It is a Grade 1 heavy duty mortise lock in the 7900 Series with a corridor/dormitory function, rose trim, and a single cylinder deadbolt. The BEST 45H with dormitory function is likewise a heavy duty, single cylinder keyed mortise lock with rose trim and a 2-3/4 inch backset. The practical difference is keying: the 45H is supplied with SFIC prep less core, so it takes a small format interchangeable core and drops into an existing SFIC master key system, while the Sargent 7925 is specified through Sargent's own cylinder program.
7) I need a mortise lock for an apartment entry door but the 45H dormitory function is not what I want. What else works?
For a straight entrance/apartment mortise function, the Baldwin 6301 is built for that use - it is offered as knob by knob or as lever by lever with the 6301LS, with a 2-1/2 inch backset and rated for doors 1-3/4 inches and over. Note the backset difference: the BEST 45H is a 2-3/4 inch backset lock, so the two do not share a door prep. If the door is already mortised for 2-3/4 inch, staying with the 45H and changing function is the simpler path.
8) What mortise lock should I specify instead of the BEST 45H for a behavioral health or patient room?
Anti-ligature trim is the deciding factor there, and the 45H is a conventional lever and knob lock. TownSteel's MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with a passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with ligature resistant arch trim. Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. Where ligature resistance is not required, the 45H is offered with UltraShield antimicrobial finishes in 626AM satin chrome and 630AM satin stainless for healthcare use.
9) Which trim and lever do I need to specify when ordering a 45H?
Three things get specified beyond finish. Trim style: H rose 2-3/4 inch flat, R rose 2-3/4 inch concave, or S rose 3-1/2 inch flat. Lever 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. Then finish. Note that the Grade 1 security upgrade path with sectional (rose) trim runs through the 1EK7K4 cylinder rather than a drill resistant core.
10) Is there an antimicrobial option for healthcare or senior living doors?
Two finishes carry the BEST UltraShield antimicrobial coating: 626AM satin chrome and 630AM satin stainless steel. The coating inhibits growth of bacteria and other microbes on the hardware surface. BEST calls it out for hospital and healthcare, elderly care, education, transportation, food service and hospitality openings where cleanliness matters.
11) I need a classroom or storeroom function instead of dormitory - what else is there?
The 45H on this configuration is dormitory only. For classroom in a Grade 1 mortise, the Corbin Russwin ML2003 and the Cal-Royal NM8070 both cover 1-3/4 inch doors. For storeroom, look at the Cal-Royal NM8080, which offers an interchangeable core option, or the Accentra 8805FL with Arcadia lever. Office/entrance is the Cal-Royal NM8050, and privacy with deadbolt is the NM8440.
12) Is the BEST 45H an electronic or credential-based lock?
No, it is a purely mechanical keyed mortise lock. If the project calls for keypad or card access on the same openings, the mortise alternatives include the Dormakaba E-Plex 2066 pushbutton keyless, the Schlage CO-100 standalone with keypad reader, the TownSteel FME-2000 with RFID, or the Accentra nexTouch NTM623-NR with a capacitive touchscreen keypad and cylinder override. Mixing mechanical 45H on back-of-house and electronic on controlled doors is common.
13) Will the 45H latch into the strike that is already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, both from a 2-3/4 inch backset. An existing ANSI mortise strike in the frame will usually catch, but the deadbolt needs a strike box deep enough for the full 1 inch throw. BEST sells a matched strike package with the lock, and on a retrofit it is worth replacing the strike so the latch and deadbolt align on the first try.
14) Can I use an electronic mortise lock in place of the BEST 45H on dorm rooms?
Only if the opening is within the electronic lock's door range. The BEST 45H is a mechanical, non-electronic keyed lock in a standard configuration for 1-3/4 inch doors, with thick door configurations available up to 5 inches. The Alarm Lock DL3500CR and DL2700CR Trilogy electronic mortise locks are Grade 1 but list a door thickness range of 1-5/8 to 1-7/8 inches, so thick doors are out. The TownSteel FME-2000 is a Grade 1 heavy duty RFID mortise lockset for 1-3/4 inch doors, and Schlage's ENGAGE LEMD-GRW is a Grade 1 wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. Electronic units also bring power, credential, and programming requirements the 45H does not.
15) The room only needs a privacy lock, not a keyed dormitory lock. What mortise options cover that?
The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches, which matches the 45H's 2-3/4 inch backset prep. The BEST 45H is a keyed single cylinder lock, so it is the choice when the room needs key control rather than occupant-only privacy.
16) What is the simpler option if the door does not need to lock at all?
For a non-locking opening, a passage mortise lock is the straightforward swap. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock that is field reversible and fire rated, and the Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset, matching the 45H backset. The BEST 45H is keyed with a single cylinder, so it carries cylinder cost and keying setup a passage lock does not.
17) Will a Sargent 4874 mortise deadbolt or a Kaba Ilco 185 work in place of the 45H?
Neither is a substitute - they are deadbolt-only bodies with no latch or lever function. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 Series, and the Kaba Ilco 185 Series is a non-handed mortise deadbolt. The BEST 45H is a complete dormitory function lockset with lever or knob trim on a 2-3/4 inch backset. A deadbolt body is an add-on for an opening that also needs a latch, not a replacement for the lockset.
18) I need the dorm door to release on a card reader or access control. What replaces the 45H?
For electrified mortise operation, the Command Access ML190 is a heavy duty motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC, supplied in a storeroom function. Schlage's L9092EU electrified mortise with 03A trim is a heavy duty keyed corridor function lock with request to exit, running 12/24VDC on 1-3/4 inch doors. The BEST 45H is a mechanical key-operated lock with no electronic option, so it is the right choice only where the opening stays offline.
19) Is the Dormakaba Saffire LX-I-M002 an equal-grade alternative to the BEST 45H?
They are not rated the same. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access, rated BHMA Grade 2. The BEST 45H meets ANSI A156.13 Series 1000 Grade 1 operation and strength. If the specification calls for Grade 1 on a mortise opening and you want credentials rather than keys, the TownSteel FME-2000 RFID mortise lockset is Grade 1 heavy duty for 1-3/4 inch doors.
20) What finishes can I get the BEST 45H in to match the rest of my building?
Fourteen finishes: 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, 626AM antimicrobial satin chrome, 630 satin stainless, 630AM antimicrobial satin stainless, and 690 statuary dark bronze. Two behave differently over time on purpose: 613 is meant to wear to an antique look, and 690 stays a dark brown. If you are standardizing a corridor, 626 and 630 are the usual institutional picks.
21) How durable is the 45H case for a high-traffic dorm corridor?
Heavy duty build: 0.095 inch cold rolled steel case, cover and armored front, zinc dichromate plated for corrosion resistance. The latchbolt is solid one-piece stainless, oil-impregnated for anti-friction operation, with roughly 50 percent more surface contact with the strike than a conventional latch. The hub runs on roller bearings. The armored front wraps both latch and deadbolt for lateral strength.
22) Is an Emtek mortise entrance lockset an alternative to the BEST 45H?
Not for a working dormitory opening. The Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane mortise entrance locksets are dummy function, meaning fixed trim with no latch operation - they suit an inactive leaf. The BEST 45H is an ANSI A156.13 Grade 1 keyed dormitory lockset for high-traffic institutional doors. If you need matching dead trim on the inactive leaf of a pair, Schlage's L0170 is a Grade 1 half dummy mortise trim for 1-3/4 inch doors.
23) For an office suite door, is the 45H the right function or should I look at an office mortise lock?
An office function is the better fit for a suite door that gets locked and unlocked from inside during the day. The Cal-Royal NM8050 is a 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 to 2-1/2 inches. The BEST 45H is a keyed dormitory function lock intended for apartment and dormitory openings.
