BEST 45H7IND15H626 – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a door thicker than 1-3/4 inches?
The standard 45H lock configuration is built for 1-3/4 inch doors. BEST does offer a thick door configuration for doors up to 5 inches, but the thickness has to be specified at time of order, so it is not something you can adapt after the fact. For anything over 1-3/4 inches, order the thick door build.
2) What does the IND intruder deadbolt function on a BEST 45H actually do?
It is a double keyed lock: key cylinders on both sides operate the deadbolt, so a teacher or occupant can throw the 1 inch stainless deadbolt from inside the room with a key without stepping into the corridor. The 45H carries a 3/4 inch stainless latchbolt alongside it, and both are shrouded by the armored front.
3) Does the BEST 45H mortise lock come handed, or can I change the hand on site?
Non-handed. The latch is reversible and rotates 180 degrees for a handing change without opening the case, and the auxiliary bolt is non-handed as well. One lock covers all four hands, so you can stock a single part number across a building.
4) Does the BEST 45H ship with cylinders or cores?
It comes prepped for a small format interchangeable core and is supplied less core, so you supply cores keyed to your existing BEST system. A cylinder security screw keeps the cylinder from being removed until the core is pulled, and solid machined cylinder rings with a wavy washer resist wrenching.
5) What ANSI grade does the BEST 45H mortise lock meet, and how do I get Grade 1 security?
The 45H meets ANSI A156.13 Series 1000, Grade 1 Operation and Strength, Grade 2 Security. To reach Grade 1 Security you must use a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or a 1EK7K4 high security cylinder with sectional trims. If Grade 1 security is written into the spec with no core substitution allowed, the 47H Series is Grade 1 for operation, strength and security as built. The 45H design also meets the intent of ANSI A117.1 section 404.2.6.
6) Is there an electronic mortise lock with an intruder classroom function equivalent to the BEST 45H IND?
The BEST 45H is a mechanical lock with no electronics. If the job calls for credential control on the same opening, the TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID technology, Grade 1 heavy duty 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. Both change the lock from key-only operation to credential-based access, so power, credential enrollment, and access control coordination become part of the job.
7) What is a comparable Grade 1 mortise lock if the opening needs a storeroom function instead of an intruder deadbolt?
The BEST 45H with intruder deadbolt function is double keyed and drives a 1 inch stainless deadbolt from either side, which is a classroom-security style arrangement rather than a storeroom one. If the door simply needs to stay locked outside with free egress and no deadbolt, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, which suits shops already keying to a small format core like the 45H's SFIC prep less core.
8) Do the Marks USA 21AC and 22AC double cylinder mortise locks substitute for the BEST 45H double keyed lock?
They share the double cylinder idea but not the application. The BEST 45H is a commercial heavy duty Grade 1 mortise lock built on a 0.095 inch cold rolled steel case for 1-3/4 inch doors, with a thick door configuration available up to 5 inches. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, listed for 1 inch door thickness, which is storefront and iron gate territory rather than a standard commercial wood or hollow metal door. Confirm the door thickness before treating either as an alternative.
9) For a behavioral health or patient room door, is the BEST 45H the right mortise lock?
The BEST 45H is a commercial heavy duty mortise lock offered with knob and lever trims including gull wing, curved, and contour styles, plus antimicrobial 626AM and 630AM finishes intended for healthcare and elderly care. It is not an anti-ligature design. Where ligature resistance is the governing requirement, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel, the MRX-A-01 is a ligature resistant arch trim version, 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.
10) Which mortise lock should I specify instead of the BEST 45H if the opening has to be electrically controlled from an access control panel?
The BEST 45H is mechanical only. For a hardwired electrified mortise lock, the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors. The Command Access ML190 Series is a heavy duty motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC and a storeroom function, which is useful when the fail state is not settled at the time of order.
11) What do I have to specify when ordering a BEST 45H with rose trim?
Four things: finish, lever or knob style, rose style, and door thickness if it is over 1-3/4 inches. Rose choices are H (2-3/4 inch flat), R (2-3/4 inch concave) and S (3-1/2 inch flat). Lever and knob options include 12 solid tube without return, 3 solid tube with return, 4 round knob, contour with angle return, curved with and without return, and gull wing. Cores are ordered separately.
12) Which BEST 45H finish should a hospital or school specify?
For high-touch openings BEST offers two UltraShield antimicrobial finishes, 626AM satin chrome and 630AM satin stainless, which inhibit bacterial and microbial growth on the hardware surface. BEST recommends them for healthcare, elderly care, education, transportation, food service and hospitality. If antimicrobial is not a requirement, the standard 626 and 630 are the usual institutional picks out of the fourteen finishes offered.
13) What is the difference between rose trim and escutcheon trim on a BEST 45H, and does it affect security?
Rose trim is a compact round plate at the lever or knob; escutcheon is a full plate. The difference matters for the security rating: to hit Grade 1 Security you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, while sectional trims require the 1EK7K4 high security cylinder. Rose options are the 2-3/4 inch flat, 2-3/4 inch concave, and 3-1/2 inch flat.
14) I only need a deadbolt on the door, not a full lockset. What is the alternative to the BEST 45H?
The 45H intruder deadbolt version is a complete mortise lockset with lever or knob trim plus a 1 inch stainless deadbolt on a 2-3/4 inch backset. If the opening needs deadbolting only, with no latch or handle, the Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series on the same 2-3/4 inch backset, so the mortise pocket and key control logic stay familiar. The Kaba Ilco 185 Series mortise lock is also a deadbolt function offered with no handing.
15) What is a simpler mortise lock if the door does not need to be keyed at all?
The BEST 45H intruder deadbolt version is a keyed lock with a double cylinder function, so both sides take a core. For a non-keyed opening in the same mortise pocket family, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, the Hager 3810S is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset matching the 45H, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. For a bed and bath opening, the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset.
16) What is the closest alternative to the BEST 45H for a dormitory or corridor door that needs a deadbolt thrown from inside only?
The BEST 45H intruder deadbolt function is double keyed, meaning a key is required on both sides to operate the deadbolt. If the opening instead needs a single cylinder deadbolt with a dormitory exit arrangement, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt in the 7900 Series, and it matches the 45H's rose trim approach rather than an escutcheon.
17) Can I use an Alarm Lock Trilogy DL2700CR or DL3500CR in place of the BEST 45H on the same door?
Only if the door is within their thickness range. The BEST 45H is built for 1-3/4 inch doors as standard with a thick door configuration available up to 5 inches. The Alarm Lock DL2700CR and DL3500CR are Grade 1 electronic classroom function mortise locks rated for doors 1-5/8 inch to 1-7/8 inch, so anything thicker is out. They also replace mechanical key-only control with keypad codes, and the DL3500CR holds 300 user codes. For a keypad deadbolt rather than a lockset, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad over the same 1-5/8 to 1-7/8 inch range.
18) Is an Emtek Brisbane or Memphis mortise entrance set an alternative to the BEST 45H?
No, they serve different purposes. The BEST 45H is a keyed commercial Grade 1 mortise lock with a working latch and 1 inch deadbolt. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are dummy function, meaning they are inoperable trim with no latching or locking mechanism. They are used on inactive leaves and pull doors, not on an opening that has to secure. The Schlage L0170 is another dummy option, a Grade 1 half dummy trim for 1-3/4 inch doors.
19) What is the difference between choosing the BEST 45H and a Cal-Royal NM8050 office/entrance mortise lockset?
Both are Grade 1 heavy duty mortise locksets for 1-3/4 inch doors. The BEST 45H in the intruder deadbolt version is double keyed with a 1 inch stainless deadbolt and comes prepped for a small format interchangeable core less core, with rose trim in 2-3/4 inch flat, 2-3/4 inch concave, or 3-1/2 inch flat. The Cal-Royal NM8050 is an office/entrance function Grade 1 mortise lockset with an auxiliary deadlatch, which controls the latch rather than throwing a separate deadbolt. Choose on function: deadbolting from both sides versus a lockable office latch.
20) If I want keyless entry with a card or mobile credential rather than the BEST 45H keyed mortise lock, what are the options?
The BEST 45H is keyed with a small format interchangeable core prep and no electronics. For credential based mortise options, 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, mobile enabled deadbolt with LED, Greenwich trim, right hand, with a 3 hour fire rating; and the Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. Note the LEMD-GRW is handed right, unlike the reversible 45H latch.
21) Is the 613 oil rubbed bronze on a BEST mortise lock going to stay the same color?
No. The 613 oxidized satin bronze oil rubbed finish is made to wear over time and take on an antique appearance, so openings installed at different dates will not match. If you want a dark finish that holds its look, 690 dark bronze coated stays a dark brown appearance over time.
22) How durable is the BEST 45H case for a high-traffic corridor?
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 hub runs on a roller bearing mechanism, and the one-piece stainless anti-friction latch gives 50 percent more surface contact with the strike. It is classed heavy duty and commercial.
