BEST 45H7AB3J613VIB – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a door thicker than 1-3/4 inches?
The standard 45H lock body is built for 1-3/4 inch doors. If your opening is thicker, BEST makes a thick door configuration that covers doors up to 5 inches, but you have to specify the actual thickness at time of order. It is not something you adjust in the field, so measure the leaf before you write the order.
2) Does the BEST 45H come with a core, and what cylinder does it take?
The 45H ships with an SFIC housing prepped less core, so the small format interchangeable core is not included. You order it separately and key it into your existing BEST SFIC system. It is a single cylinder keyed function. One thing worth knowing on the security side: the 45H is rated Grade 2 Security as standard, and to reach Grade 1 Security a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) must be used with escutcheon trims, or the 1EK7K4 high security cylinder with sectional trims.
3) What does the office function do on a BEST 45H, and how does the visual indicator read?
Office function means the outside lever can be locked or unlocked from inside, typically by thumbturn or key, and the inside lever always retracts the latch for free egress. What the 45H adds is a double visual indicator: an open padlock icon when the door is unlocked, and a closed padlock icon with red paint when it is locked. Both sides show it, so someone in the corridor and someone in the room can both read the status without trying the lever. That is why these go into offices, conference rooms and any space where staff need to confirm the door is secured during a lockdown.
4) Do I have to order the BEST 45H handed, or can I change the hand in the field?
Hand is a required selection when you order (left hand, right hand, left hand reverse, right hand reverse), but you are not stuck with it. The latchbolt is reversible, rotating 180 degrees without opening the case, and the hub uses a four position toggle design. So a lock that arrives set the wrong way can be flipped on the job rather than returned. For a property manager stocking spares across a building, that means one lock body covers openings of either hand.
5) What ANSI grade is the BEST 45H mortise lock, and is it accessible-compliant?
ANSI A156.13, Series 1000, Grade 1 Operation and Strength, Grade 2 Security. BEST also states the design and operation meet the intent of ANSI A117.1 section 404.2.6, the accessibility requirement for door hardware operation. If your spec demands Grade 1 across all three categories including Security, the 47H series is the one that carries it; on the 45H you get there on the security line only by adding a drill resistant core or the high security cylinder.
6) What is the closest Grade 1 mortise office-function lock to the BEST 45H if I need a non-keyed office lock instead of an SFIC keyed one?
The Hager 3850E is an office function mortise lock with a 2-3/4 inch backset supplied non-keyed with lever and escutcheon, and it fits doors 1-3/4 inch through 2-1/2 inch thick. The BEST 45H is also office function on a 2-3/4 inch backset, but it is a keyed single cylinder lock with an SFIC prep less core, so the core is ordered separately and keyed into a small format interchangeable core system. If the opening needs office operation without a cylinder in it, the 3850E covers that; if the opening has to sit in an SFIC keying system, the 45H is the one that accepts the core.
7) I need the same heavy duty mortise lock but in storeroom function - what do I order?
Storeroom function in a heavy duty mortise body is covered by the Accentra 8805FL, a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and by the Cal-Royal NM8080, a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for doors 1-3/4 inch thick. The BEST 45H body is built for office function, where the outside lever is locked and unlocked by key. Storeroom function keeps the outside lever locked at all times and retracts the latch by key only, so it is a different lock body rather than a trim or finish change on the 45H.
8) Is the Cal-Royal NM8050 a substitute for the BEST 45H office lock?
The Cal-Royal NM8050 is a heavy duty Grade 1 entrance/office mortise lockset with an auxiliary deadlatch for doors 1-3/4 inch thick, so it lands on the same office-style operation as the BEST 45H, which is a heavy duty commercial mortise lock in office function. The difference that decides it is the cylinder and the indicator: the 45H ships with an SFIC prep less core so it takes a small format interchangeable core, and it carries a double visual indicator that reads open or locked at the trim. If the facility keys on SFIC or the room needs visible status at the door, those two points are the 45H's; if neither applies, the NM8050 covers the same office opening.
9) Can I use a Baldwin 6301 or 6310 mortise lock body in place of the BEST 45H?
No - the backsets differ. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies are 2-1/2 inch backset, offered knob by knob or lever by lever, while the BEST 45H is a 2-3/4 inch backset lock. A 2-1/2 inch body will not drop into a mortise pocket cut for 2-3/4 inch without re-prepping the door and the trim holes. The Baldwin 6301 fits doors 1-3/4 inch and over and the 6310 fits 1-3/8 inch and over, and they carry entrance/apartment and entrance/storeroom functions rather than the office function of the 45H.
10) My door is 1-5/8 inch thick - will the BEST 45H work, or do I need something else?
The BEST 45H standard configuration is built for doors 1-3/4 inch thick, with a thick door configuration for doors up to 5 inch when the thickness is specified at order. For a thinner door, the Alarm Lock DL2700CR classroom mortise lock and the DL4500 mortise deadbolt are both listed for doors 1-5/8 inch to 1-7/8 inch, as is the DL3500CR. Those are electronic keypad locks rather than key-operated mortise locksets, so the trade is thickness range against mechanical key operation.
11) What trim and lever do I have to pick when ordering a BEST 45H?
Three choices beyond finish and hand. Trim style is H rose, R rose, or J wrought escutcheon. Lever style covers 12 solid tube with no return, 3 solid tube with return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, and 4 which is a round knob rather than a lever. The trim choice is not cosmetic only: escutcheon trims and sectional trims take different high security cylinder options if you are chasing Grade 1 Security.
12) Is there a BEST 45H finish suitable for a hospital or food service application?
Two of the fourteen finishes carry the UltraShield antimicrobial protected coating: 626AM satin chrome and 630AM satin stainless steel. The coating inhibits growth of bacteria and other microbes on the hardware surface, and BEST calls it out for hospital and elderly care, education, transportation, food service and hospitality. Standard finishes run 605 bright brass through 690 dark bronze, including 613 oxidized satin bronze, which is meant to wear to an antique look over time.
13) I need a mortise lock with a visual indicator but not office function. What else is there?
If the room needs classroom security instead of office, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors, with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches. It differs from the 45H in function: classroom security lets a teacher lock the corridor lever from inside the room with a key, where office function is set and left. If you want office function without the indicator and without an SFIC prep, the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on the same 2-3/4 inch backset, non-keyed, and it is rated for doors 1-3/4 to 2-1/2 inches.
14) Can I use a BEST 45H on an access controlled opening?
No. The 45H is a mechanical lock with no electrical option, so it will not lock or unlock from a card reader or an access control panel. For an electrified mortise lock on the same kind of opening, the Schlage L9092EU with 03A trim gives electric lock/unlock of the outside lever with request-to-exit, keyed outside, on 12/24VDC for 1-3/4 inch doors, and the Command Access ML190 is a motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC. Keep the 45H where you want mechanical key control and a visible lock status, not remote control.
15) Is the BEST 45H heavy enough for a high traffic entrance that gets hundreds of cycles a day?
It is built for that duty. The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated for corrosion protection, with a solid one-piece stainless steel anti-friction latchbolt that BEST states gives 50 percent more surface contact with the strike. The hub runs on roller bearings, and the lever return spring sits in the trim rather than the case, which is the part that fights lever droop on doors that get pulled on all day. The auxiliary bolt is stainless and non-handed.
16) Should I use a mortise lock like the BEST 45H or a cylindrical lock on my doors?
Mortise is the right call when the door already has a pocket cut for one, when you need a deadbolt and latch in a single body, or when the opening sees heavy commercial traffic. The 45H carries a 1 inch deadbolt throw alongside a 3/4 inch latch in one case, which a cylindrical lock cannot give you. The trade is preparation: a mortise pocket is a routed cavity in the door edge, not two bored holes, so retrofitting a cylindrical-prepped door to mortise is real millwork. If your doors are bored for cylindrical, something like the Schlage PC10 Grade 1 passage cylindrical lock is the matching prep, and you would stay in that family.
17) The BEST 45H is more lock than I need for an interior door with no key - what is the simpler option?
For an opening that never needs a key, the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, 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. Hager's 3810S and 3810E are Grade 1 passage mortise locks on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, the 3810S with rose trim and the 3810E with escutcheon. The BEST 45H is a keyed single cylinder lock with an SFIC prep, so on a passage opening the core prep and the indicator go unused.
18) What looks like a BEST 45H mortise lock but is only trim or a deadbolt?
Several mortise-family parts are not complete locksets. The Schlage L0170 is half dummy trim, a non-keyed Grade 1 mortise lever with no latch operation, for 1-3/4 inch doors. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function as well. The Sargent 130KB and 130W are mortise thumbturns, and the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch or lever. The BEST 45H is a complete keyed single cylinder mortise lockset with a latch and lever trim, so none of those parts substitute for it.
19) If I want keypad or credential access on this opening instead of a key, what mortise lock do I use?
The BEST 45H is a mechanical lock with no electronics, keyed to a single cylinder. For credential or code access in a mortise body, the Schlage CO-100 is a standalone electronic mortise lock with a keypad reader, Grade 1 heavy duty, privacy function, for 1-3/4 inch doors. The Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for doors 1-5/8 inch to 1-7/8 inch. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors.
20) Behavioral health unit - can I put the BEST 45H on a patient room door, or do I need anti-ligature trim?
For anti-ligature openings the TownSteel MRX-A-01 is a Grade 1 heavy duty passage mortise lockset with satin stainless steel ligature resistant arch trim for 1-3/4 inch doors, and the MRX-L-01 is the stainless steel Grade 1 heavy duty anti-ligature lever version on the same thickness. 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 lever and knob trim in rose or escutcheon styles, which is the right choice for a staff or office door on the unit rather than a patient room; where cleanliness drives the finish, it offers 626AM and 630AM UltraShield antimicrobial finishes.
21) Restroom door - is the 45H the right lock, or should I use a privacy mortise lock?
A restroom wants privacy function, which the BEST 45H does not provide; the 45H is a keyed office function lock. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for doors 1-3/4 inch thick, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch, matching the 45H backset so the door prep carries over.
22) Dorm corridor door - how does the Sargent 7925 compare to the BEST 45H?
The Sargent 7925 is a Grade 1 heavy duty corridor/dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. The BEST 45H is a heavy duty office function lock, keyed single cylinder, with a double visual indicator reading locked or unlocked. The 7925 puts a deadbolt in the door for the dormitory exit sequence; the 45H holds the room secure through the keyed outside lever and shows status at the trim, which is what a resident or staff member reads from the corridor side.
23) Which of these mortise locks handles an entrance with an interchangeable core keying system?
The BEST 45H comes with an SFIC prep less core, so it is ordered without the core and takes a small format interchangeable core keyed to the facility's system. Among the comparable mortise locks, the Cal-Royal NM8080 storeroom lockset is offered with an interchangeable core option, and the Accentra NTM623-NR nexTouch mortise lock has a cylinder override. If a facility is standardizing on interchangeable cores across a building, the 45H and the NM8080 are the two that accept them by design.
