BEST 45H7IND3J626 – Frequently Asked Questions

1) What does the IND intruder deadbolt function on the BEST 45H mortise lock actually do?
The IND function is a double-cylinder setup: key operates the deadbolt from either side of the door. That means someone inside a classroom or office can throw the 1 inch stainless deadbolt with a key without stepping into the corridor, and it can also be keyed from outside. Because both sides are keyed rather than thumbturn, egress codes for the opening need to be checked against your local requirement before you specify it.
2) Does the BEST 45H come with a core, or do I need to order cylinders separately?
It ships with SFIC prep and no core. You supply the small format interchangeable core, which is what most facilities running a BEST keyway want, since it lets you key the lock into an existing system on site. The IND function is double keyed, so plan on two cores per lock. A security screw keeps the cylinder from being removed until the core is pulled first.
3) Is the BEST 45H Grade 1, and does it meet Grade 1 security as shipped?
The 45H is ANSI A156.13 Series 1000, Grade 1 for operation and strength, Grade 2 for security. To reach Grade 1 security with escutcheon trim, you have to specify a drill resistant core (1CD, 1CDP, 1CDF or 1CDX). With sectional trims, the 1EK7K4 high security cylinder is what gets you there. If your spec calls for Grade 1 security across all three categories out of the box, the 47H Series is the one that carries it.
4) Which mortise locks besides the BEST 45H cover doors thicker than 2 inches?
The BEST 45H offers a thick door configuration for doors up to 5 inches when the thickness is specified at time of order, beyond the standard 1-3/4 inch build. Among the alternatives, the Hager 3810E and 3810S passage mortise locks cover 1-3/4 inch to 2-1/2 inch doors, while the Alarm Lock DL3500CR and DL2700CR electronic classroom mortise locks are limited to 1-5/8 inch to 1-7/8 inch, and most Grade 1 mechanical locksets such as the Cal-Royal NM8080 are built for 1-3/4 inch.
5) What is a comparable Grade 1 mortise lock for a classroom door if the intruder deadbolt function is more than the opening needs?
For a straightforward classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series listed for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset also listed for 1-3/4 inch doors. The BEST 45H with intruder deadbolt function is a keyed double cylinder mortise lock with a 2-3/4 inch backset, so it adds key-operated deadbolt control from both sides that a plain classroom function does not provide.
6) Is there an electronic mortise lock with a classroom intruder function instead of a keyed one?
Yes. The TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID technology, Grade 1 heavy duty, listed for 1-3/4 inch doors, and the TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID for the same door thickness. The BEST 45H intruder deadbolt lock is a non-electronic mechanical lock, so it needs no power, credentials, or head-end setup and is keyed instead.
7) If I only need a deadbolt keyed from both sides and not a full lockset, what should I order?
The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset, which matches the backset of the BEST 45H. The 45H with intruder deadbolt function is a complete lockset with lever or knob trim and a double cylinder keyed function, so it handles latching and day-to-day passage as well as the deadbolt; the 4874 is deadbolt only and would need separate trim or a latch for normal door operation.
8) Can I use an office or storeroom mortise lock in place of the BEST 45H on a commercial corridor door?
Function is the deciding factor. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, and the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset. Storeroom and office functions latch and key from the outside but do not provide the key-throwable deadbolt from either side that the 45H intruder deadbolt configuration gives, so they substitute only if the deadbolt is not required.
9) We use small format interchangeable cores throughout the building. Which of these mortise locks fits that program?
The BEST 45H is supplied with SFIC prep less core, so it drops into an existing small format interchangeable core keying program. Among the alternatives, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset is offered with an interchangeable core option. Locks such as the Corbin Russwin ML2003 Grade 1 classroom mortise lockset are keyed cylinder locksets in the ML2000 Series and would be keyed to their own system.
10) What mortise lock works for a behavioral health or ligature-resistant opening rather than the 45H with lever trim?
For those openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, 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 conventional lever and knob trim styles such as curved with return, gull wing, and round knob, which are not ligature-resistant profiles.
11) Will a Marks USA 21AC or 22AC ornamental iron mortise lock work in the same door as the BEST 45H?
No. The Marks USA 21AC and 22AC entrance double cylinder ornamental iron mortise locks are listed for 1 inch thick doors, which suits narrow ornamental iron stiles. The BEST 45H standard configuration is designed for 1-3/4 inch doors with a thick door configuration available up to 5 inches, so the two are not interchangeable even though both are double cylinder mortise locks.
12) What should I use for an aluminum storefront or narrow stile door rather than the BEST 45H?
The BEST 45H is a heavy duty mortise lock for commercial wood and hollow metal doors at 1-3/4 inch standard thickness. For narrow stile and glass door work, the Kaba Ilco BR Series is a glass door bottom rail lock, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches, and the Dormakaba E-Plex E2066 is an electronic pushbutton keyless mortise lock in a wide stile configuration.
13) Do I have to order the BEST 45H handed?
No. The latch is reversible and rotates 180 degrees to change hand without opening the lock case, and both the cylinder retainer and the auxiliary bolt are non-handed. That makes it a practical stock item for a property manager keeping spares for a building with mixed openings.
14) Which escutcheon trim style should I order on the BEST 45H?
Three escutcheon options: J is wrought, M is forged, and N is forged with a concealed cylinder. N hides the cylinder behind the plate, which is the one people pick when they want the keyway less obvious on a corridor or public-side door. Lever choices run across seven styles including solid tube with and without return, curved with and without return, contour with angle return, gull wing, and a round knob.
15) Is there a BEST 45H finish suitable for a hospital or school where surfaces get wiped constantly?
Two antimicrobial options: 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. Fourteen finishes in total, from 605 bright brass through 690 dark bronze, so you can match the rest of the building on non-critical openings and run AM only where it matters.
16) How does the BEST 45H IND compare to an electronic classroom intruder lock like the TownSteel FME-4000?
Both address the same problem, locking down an opening from inside. The 45H IND is purely mechanical with no electronics, so there are no batteries, no credentials and nothing to fail when power drops, but it needs a key in hand to throw the deadbolt. The TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID, Grade 1 heavy duty, for 1-3/4 inch doors, which gives you credential management and audit at the cost of a power source. If your district wants no-key lockdown, look electronic; if you want zero maintenance, stay with the 45H.
17) What is a mechanical alternative to the BEST 45H if I do not need the intruder deadbolt?
If the opening only needs storeroom or classroom keying, other Grade 1 mortise locks cover it without the double cylinder. The Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, also 1-3/4 inch. Both skip the second keyed cylinder the 45H IND carries.
18) Will the BEST 45H meet accessibility requirements 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. Lever styles with a return (solid tube with return, curved with return, contour with angle return) are the usual pick where the spec calls for a returned lever; the round knob option would not suit an accessible opening.
19) What is a simpler mortise lock for a door that does not need to be keyed at all?
For non-keyed openings, the Schlage PM010 is a Grade 1 passage latch mortise lock 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 passage mortise lock with escutcheon trim and a 2-3/4 inch backset. The BEST 45H intruder deadbolt version is keyed, so if there is no security requirement on the opening a passage function avoids cylinders and keying altogether.
20) I need a dormitory or corridor function with a deadbolt. What compares to the 45H intruder deadbolt?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt. The BEST 45H intruder deadbolt version is a double cylinder keyed lock offered with escutcheon trim in wrought, forged, and forged concealed cylinder styles, so the difference is single versus double cylinder deadbolt control and rose versus escutcheon trim.
21) Is there an access-controlled mortise lock I can tie into a card or mobile credential system instead of the mechanical 45H?
Several. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating, and the Dormakaba E5086 is a Grade 1 pushbutton/card back-to-back mortise lock. The BEST 45H is a mechanical, non-electronic lock, so it requires no reader, batteries, or credential management.
22) For a healthcare corridor where cleanability matters, does the 45H or one of the alternatives make more sense?
The BEST 45H is offered in 626AM satin chrome antimicrobial and 630AM satin stainless steel antimicrobial finishes with the UltraShield coating, which inhibits growth of bacteria and other microbes on the hardware surface. If the opening needs hands-free operation instead, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel that is ADA compliant.
23) Is there an electrified mortise lock that matches the 45H for access control retrofit on the same opening?
The Command Access ML190 Series is a heavy duty motorized mortise lock with field selectable electrified locked or unlocked operation on 24VDC in storeroom function, and the Schlage L9092EU electrified mortise lock is a heavy duty corridor function lock for 1-3/4 inch doors, keyed outside, with request to exit and 12/24VDC operation. The BEST 45H is a mechanical lock with no electrical connection, so an electrified option requires power transfer hinges or a similar raceway to the door.
24) For classroom security with a visual indicator, how does the Marks LA318GJ compare to the BEST 45H intruder deadbolt?
The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors, supplied with an ANSI strike and a steel escutcheon measuring 8-1/2 inches H x 2-3/4 inches W x 7/16 inch. The BEST 45H intruder deadbolt lock is a Grade 1 operation and strength double cylinder lock with an 8 inch H x 1-1/4 inch W x 1/16 inch T faceplate, offered with wrought, forged, and forged concealed cylinder escutcheon trims.
25) Would a cylindrical lock do the same job as the 45H mortise lock?
Only where the door is prepped for it. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors and mounts in a bored prep. The BEST 45H is a mortise lock requiring a mortise pocket in the door edge and an 8 inch H x 1-1/4 inch W faceplate, so moving between the two means re-prepping the door.
26) I only need a deadbolt, not a full mortise lockset. Is the BEST 45H IND overkill?
Probably. The 45H IND is a complete mortise lock body with latch, deadbolt and escutcheon lever trim. If the door already has a separate latch or panic device and you just want a keyed bolt, a straight mortise deadbolt such as the Sargent 4874 double cylinder with a 2-3/4 inch backset does the job with far less door prep.
27) Is the BEST 45H built for high-traffic commercial openings or light residential use?
Commercial, heavy duty. The case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating, the latch is solid one-piece stainless with a hub on roller bearings, and the case is closed with four corner screws plus an interlocking design. The armored front wraps both latch and deadbolt for lateral strength. It is not a residential-grade part and it is not priced or prepped like one.
28) Is a Schlage L0170 half dummy trim an alternative to the 45H?
Only for an inactive leaf. The Schlage L0170 is a Grade 1 heavy duty non-keyed half dummy mortise lever trim for 1-3/4 inch doors, and the Emtek 3104 Hamilton and 3106 Manhattan are dummy mortise entrance locksets - none of them latch or lock. The BEST 45H is a keyed working mortise lock with a double cylinder function.
