BEST 45H7T3J605VIB – Frequently Asked Questions

1) Does the BEST 45H mortise lock come with a core, or do I have to order the SFIC core separately?
It ships as an SFIC housing less core, so the small format interchangeable core is a separate order. That is what lets you drop it straight into an existing BEST-style master key system, or rekey later without pulling the lock. Worth knowing if security grading matters: the 45H meets ANSI A156.13 Series 1000 Grade 1 Operation and Strength but Grade 2 Security as standard. To reach Grade 1 Security you have to specify a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim.
2) Will the BEST 45H mortise lock fit a door thicker than 1-3/4 inches?
The standard configuration is built for 1-3/4 inch doors, which covers most commercial openings. For anything thicker, BEST offers a thick door configuration up to 5 inches, but the thickness has to be called out at time of order. It is not something you adjust in the field, so measure the leaf before you place the order.
3) Will the deadbolt on this BEST mortise lock reach my existing ANSI strike?
The deadbolt throws 1 inch and the stainless latchbolt throws 3/4 inch, both from a 2-3/4 inch backset. Those are standard heavy duty mortise throws, so a properly positioned ANSI strike box with a curved lip strike will take both. If you are reusing frame prep, confirm the strike box is deep enough to clear a full 1 inch bolt.
4) What is the closest equivalent to the BEST 45H dormitory mortise lock from another manufacturer?
The Sargent 7925 is the nearest match in function and class: it is a Grade 1 heavy duty mortise lock with corridor/dormitory function, rose trim, and a single cylinder deadbolt, in the 7900 Series. The BEST 45H is also a heavy duty Grade 1 mortise lock with dormitory function and a 2-3/4 inch backset, but it adds a double visual indicator that shows an open padlock icon for unlocked and a closed red padlock icon for locked, and it is supplied with SFIC housing prepped less core. If the keying program is a small format interchangeable core system, the 45H drops straight into it; the 7925 is specified with Sargent cylinders.
5) Do I have to specify handing on the BEST 45H, and can it be changed in the field?
Handing is a required selection at order: left hand, right hand, left hand reverse or right hand reverse. The lock body itself is non-handed with a reversible latch that rotates 180 degrees, so handing can be corrected without opening the case, and the hub has four toggle positions. The auxiliary bolt is non-handed as well.
6) What does the double visual indicator on the BEST 45H dormitory lock actually show?
Two padlock icons. Open padlock means unlocked; closed padlock, painted red, means locked. Because it is a double indicator, the status reads from both sides of the door, which is why these go into student housing, patient rooms and guest rooms where someone needs to know the door state without trying the lever.
7) What trim and lever choices do I need to decide on when ordering a BEST 45H?
Three decisions beyond finish and handing. Trim style is H rose, R rose, or J wrought escutcheon. Lever style covers 3 solid tube with return, 12 solid tube no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, and 4 round knob. Trim choice also ties into security grading, since drill resistant cores pair with escutcheon trim and the high security cylinder pairs with sectional trim.
8) Is the BEST 45H ADA compliant 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 accessibility requirement for door hardware operation. Pair that with a lever rather than the 4 round knob if accessibility is the driver, since knobs generally do not satisfy accessible operation.
9) What else could I use instead of the BEST 45H dormitory indicator lock?
Depends what you are after. For the same dormitory function in a Grade 1 heavy duty mortise from another brand, the Sargent 7925 is the closest straight swap, a dormitory exit function mortise lock with rose trim and single cylinder deadbolt. If the indicator is the point rather than dormitory function, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and steel escutcheon. If you want credential or keypad access on the same opening, look at electronic mortise locks such as the TownSteel FME-2000 or the Schlage CO-100. The 45H itself is mechanical, not electronic.
10) What should I specify instead of the 45H for a restroom or patient bathroom door?
Use a privacy function mortise lock. The Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with 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. The BEST 45H is a keyed single cylinder dormitory function lock, which is a different operation: it is keyed from the outside rather than thumbturn-only privacy.
11) Can I use a Sargent 4874 or a Sargent 130KB in place of the BEST 45H?
No. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset and no latch or lever operation, and the Sargent 130KB is a standard duty mortise thumbturn from the 8200 Series, which is trim only. The BEST 45H is a complete heavy duty mortise lockset with a latch, deadbolt, lever or knob trim, and a double visual indicator on a 2-3/4 inch backset. The backset matches on the 4874, but neither part provides latching lever operation.
12) Is an electronic mortise lock an alternative to the 45H indicator lock for student housing?
It can be, if you want credential-based access instead of mechanical keys. The TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors, and the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 to 1-7/8 inches. The BEST 45H is not electronic; it is a mechanical keyed lock with SFIC housing and a double visual indicator, so it needs no power, batteries, or programming.
13) Which mortise lock should I look at if the door needs access control release rather than key-only operation?
For an electrified mortise body, 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, keyed outside, with request to exit, at 12 or 24VDC for 1-3/4 inch doors. The BEST 45H is a mechanical lock with no electrical option, so an opening tied to a card reader or a fire alarm release needs one of the electrified bodies instead.
14) Which finish should I pick for a hospital or care facility?
BEST offers two antimicrobial options on the 45H: 626AM satin chrome and 630AM satin stainless, both with the UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it for healthcare, elderly care, education, transportation, food service and hospitality. The standard range runs 605, 606, 611, 612, 613, 618, 619, 622, 625, 626, 629, 630 and 690, with 613 intended to wear to an antique look over time.
15) How durable is the BEST 45H case for a high traffic dorm or school corridor?
The case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance, held by four case cover screws at the corners with an interlocking armored front and cover at the latch. The latch is solid one piece stainless with roughly 50 percent more surface contact at the strike and an oil impregnated anti-friction action, and the hub runs on roller bearings. That is heavy duty construction, and it is graded Grade 1 for Operation and Strength under ANSI A156.13 Series 1000.
16) What do I use on the non-locking doors in the same corridor so the trim matches the 45H?
Non-keyed mortise locks in the same duty class are the usual companion. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Hager 3810E and 3810S are Grade 1 passage mortise locks with a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches, offered with escutcheon and with rose respectively. The BEST 45H is the keyed dormitory member of that set and is available in H rose, R rose, or J wrought escutcheon trim.
17) Are the Emtek mortise entrance locksets an alternative to the BEST 45H?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are all dummy function, meaning fixed trim with no latching or keyed operation. The BEST 45H is a keyed single cylinder heavy duty mortise lock for commercial use with a dormitory function and SFIC housing. Use the Emtek pieces only on an inactive leaf or a false door.
