BEST 45H7TA15J626 – Frequently Asked Questions

1) Does the BEST 45H dormitory mortise lock come with a core, or do I need to order one separately?
The lock ships with a 7-pin SFIC housing only, prepped less core, so you supply the small format interchangeable core separately and key it into your existing system. One thing to know on the security side: the 45H is rated ANSI A156.13 Series 1000 Grade 1 operation and strength with Grade 2 security. To reach Grade 1 security with an escutcheon trim like the J, a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) has to be used.
2) Will a BEST 45H mortise lock fit a 1-3/4 inch door, and what if my doors are thicker?
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 the thickness has to be specified at time of order. You cannot field-adapt a standard lock to a thick door.
3) What does the dormitory function on the BEST 45H actually do at the door?
Dormitory function means the outside lever is locked or unlocked by key, with a separate deadbolt for occupant security, and the inside lever always retracts both bolts for free egress. It is a single cylinder keyed lock. The deadbolt throws 1 inch of stainless steel and the anti-friction latchbolt throws 3/4 inch. This is the function used for student housing, apartments, hotel guest rooms and patient rooms where the resident secures the door from inside but staff can key in.
4) Do I need to specify handing when I order a BEST 45H mortise lock?
No. The 45H latch is reversible and rotates 180 degrees to change handing without opening the case, and a four-position hub toggle handles the rest of the configuration. The auxiliary bolt is non-handed. The armored front also self-aligns to the door bevel during install, so one lock covers left and right hand openings.
5) We need the same lock body but for a classroom opening instead of a dorm room. What should we order?
For a classroom opening, 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 heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors. Both keep the Grade 1 mortise format of the BEST 45H but use classroom function rather than dormitory function with a deadbolt.
6) What does the TA option add to a BEST 45H dormitory lock?
TA gives deadbolt status indication only. It is an internal switch option that reports whether the deadbolt is thrown, which is what most dorm and multi-family access systems want for occupancy or room-status monitoring. The lock itself is not electronic in operation; it is a mechanical mortise lock.
7) What is the J escutcheon and 15 lever, and how is it different from a rose trim version?
J is a stamped escutcheon plate, a full plate running behind the lever rather than a small round rose, and the 15 lever is the contour style with an angle return. The escutcheon covers more of the door face, which helps when you are replacing older trim and want to hide previous prep. Note the security rule differs by trim: with escutcheon trim the 45H reaches Grade 1 security using a drill resistant core, while sectional (rose) trims need the 1EK7K4 high security cylinder instead.
8) How does the BEST 45H compare to the Sargent 7925 for dormitory openings?
Both are Grade 1 heavy duty mortise locks for dormitory use. The Sargent 7925 from the 7900 Series is a dormitory exit function lock with rose trim and a single cylinder deadbolt. The BEST 45H here comes with a stamped J escutcheon rather than a rose, and it is prepped for a 7-pin small format interchangeable core, which matters if your campus is already keyed on SFIC. If you standardize on Sargent cylinders, the 7925 is the closer match.
9) I need the same 45H body but a different function, like classroom or storeroom. What are my options from other brands?
Dormitory function is what this 45H is built for. If the opening needs a different function, Cal-Royal's NM Series covers Grade 1 mortise in classroom (NM8070), storeroom with an interchangeable core option (NM8080), office/entrance (NM8050) and privacy with deadbolt (NM8440), all for 1-3/4 inch doors. Corbin Russwin ML2003 is a Grade 1 classroom mortise for 1-3/4 inch doors, and Accentra's 8805FL is a Grade 1 storeroom mortise.
10) Is the BEST 45H mortise lock ADA compliant for lever operation?
BEST states the design and operation of the mortise lock meets the intent of the standard for ANSI A117.1 section 404.2.6, which is the accessibility requirement for operable door hardware. The 15 contour lever with angle return is a lever, not a knob, so it operates without tight grasping or twisting.
11) Will the 45H latch engage my existing ANSI strike?
The latchbolt is solid one-piece stainless with a 3/4 inch throw and an oil-impregnated anti-friction face, and BEST states the one-piece design gives about 50 percent more surface contact with the strike. The deadbolt throws 1 inch. On a standard 2-3/4 inch backset ANSI mortise prep with a matching lip projection, it engages normally. If you are changing frames or strikes, order the strike package with the lock.
12) The door only needs to be locked from the outside with no deadbolt. Is there a simpler mortise lock than the 45H dormitory?
Yes. Storeroom function drops the deadbolt and the inside key control the dormitory function provides. 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 with an interchangeable core option for 1-3/4 inch doors. The BEST 45H keeps a keyed single cylinder dormitory function for openings where the occupant needs to secure the room.
13) Is the Cal-Royal NM8440 privacy mortise lock a substitute for the BEST 45H dormitory lock on a dorm room door?
No. The NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, intended for bed and bath openings where the bolt is thumbturn operated and there is no key. The BEST 45H dormitory lock is keyed with a single cylinder and takes an SFIC core, so it provides key control the privacy set cannot. Use the NM8440 only for a bathroom within the unit, not the entry door.
14) We want keypad access on dorm doors instead of keys. What mortise lock replaces the 45H?
Several electronic mortise locks cover that. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100-MS is a Grade 1 heavy duty standalone electronic mortise lock with keypad reader in privacy function for 1-3/4 inch doors. The Accentra nexTouch NTM623-NR adds a capacitive touchscreen keypad with cylinder override and no deadbolt. The BEST 45H is a mechanical, non-electronic lock, so it needs no power or programming.
15) The opening needs access control tied to a card system. What is the alternative to a mechanical dormitory mortise lock?
For credentialed access, the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, and the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and Greenwich trim, right hand, carrying a 3 hour fire rating. The Dormakaba LX-I-M002 Saffire is an RFID mortise lockset with BLE mobile access at BHMA Grade 2. The BEST 45H is a commercial mechanical lock with an SFIC housing rather than a reader.
16) Some doors in the building are non-locking. What matches the 45H mortise prep without a cylinder?
Passage function mortise locks use the same mortise pocket approach without keying. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, 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, and the Hager 3810E is a 3800 Series Grade 1 passage mortise lock with escutcheon and a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors. The Hager 3810E shares the 2-3/4 inch backset and escutcheon trim style used on the BEST 45H with J escutcheon.
17) The opening needs to be released electrically from an access control panel. What replaces the 45H?
The Command Access ML190 is a heavy duty motorized mortise lock in storeroom function with field selectable electrified locked and unlocked operation on 24VDC. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit on 12/24VDC for 1-3/4 inch doors. The BEST 45H is mechanical and has no electrical connection.
18) For a behavioral health unit, is the BEST 45H with the 15 lever appropriate or is there an anti-ligature option?
For ligature resistant openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel with passage function for 1-3/4 inch doors, the MRX-A-01 uses satin stainless anti-ligature arch trim in passage function, and 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 uses a contour lever with angle return and a J escutcheon, which is a standard commercial lever profile rather than a ligature resistant one.
19) Is there an antimicrobial finish option for healthcare or dorm use?
Yes. BEST offers 626AM (satin chrome plated) and 630AM (satin stainless) with the UltraShield antimicrobial protected coating, which inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it for hospital and elderly care, education, transportation, food service and hospitality work. Standard finishes run from 605 bright brass through 613 oil rubbed bronze, 626 satin chrome, 630 satin stainless and 690 dark bronze.
20) Is the 45H case strong enough for high-traffic student housing?
The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated for corrosion resistance, with four corner cover screws and an interlocking armored front. Internally it runs a roller bearing hub for wear resistance, and the anti-droop spring sits in the trim so the lever returns level instead of sagging over time. It is classified heavy duty and commercial.
21) Do I need a full dormitory mortise lock if the door only needs a deadbolt?
Not necessarily. If the opening already has a separate latch or panic hardware and only needs bolt security, the Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with the same 2-3/4 inch backset as the BEST 45H, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad. The BEST 45H combines a latch and deadbolt in one case with lever trim, which the deadbolt-only units do not provide.
22) Will the Emtek 3102 Memphis mortise entrance lockset work in place of the BEST 45H?
No. The Emtek 3102 Memphis is a dummy function mortise entrance lockset, meaning it is trim only with no working latch or bolt, as are the Emtek 3104 Hamilton and 3106 Manhattan. The BEST 45H is a keyed commercial mortise lock with a dormitory function. Use the Emtek dummy sets only on an inactive leaf.
