BEST 45H7IND3J613VIN – Frequently Asked Questions

1) Does the BEST 45H intruder function mortise lock come with a core, or do I need to order one separately?
It ships as an SFIC prep less core, so the small format interchangeable core is ordered separately and keyed to your system. It is a single cylinder keyed lock. One thing to plan for on the security spec: 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 need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or a 1EK7K4 high security cylinder with sectional trims.
2) What does the visual indicator on the BEST 45H intruder lock actually show?
A padlock icon. Open padlock means unlocked, closed padlock with red paint means locked. On an intruder function opening that is the point of the whole assembly: a teacher can key the outside lever locked from inside the room and then confirm at a glance that it took, without opening the door or stepping into the corridor.
3) Will a BEST 45H mortise lock fit a 1-3/4 inch door, and what about thicker doors?
Standard configuration is built for 1-3/4 inch doors, which covers most commercial openings. Thick door configurations are available up to 5 inches, but the thickness has to be specified at time of order, it is not field adjustable. The lock case itself is 5-7/8 H x 7/8 D x 4-1/16 W, and the faceplate is 8 x 1-1/4 x 1/16 inches, so your mortise pocket and edge prep need to accept that.
4) Do I have to specify handing when I order the BEST 45H, and can it be changed in the field?
Handing is a required selection: 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 without opening the case, plus a four position hub toggle, so a hand change on site is straightforward.
5) Will the BEST 45H latch into the strike prep I already have at a 2-3/4 inch backset?
The 45H is a 2-3/4 inch backset mortise lock, the standard commercial backset, with a 3/4 inch latchbolt throw and a 1 inch deadbolt throw. If the existing opening is a 2-3/4 inch backset mortise pocket with an ANSI strike, the geometry lines up. The armored front is staked so it self-aligns to the door bevel during installation, which takes one variable out of a retrofit. Verify your strike box is deep enough for the 1 inch deadbolt.
6) Is there an electronic version of an intruder classroom mortise lock 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, for 1-3/4 inch doors. The BEST 45H intruder lock is mechanical rather than electronic and is keyed through an SFIC housing supplied less core, so it needs no power, wiring, or credential management. Choose the FME-4000 if you want credential-based access and the 45H if the opening is managed on a key system.
7) Would a Baldwin 6310 or Marks 21AC mortise lock drop into the same door prep as the BEST 45H?
No. The Baldwin 6310 entry/storeroom mortise lock body uses a 2-1/2 inch backset, and the Marks USA 21AC ornamental iron mortise lock is built for 1 inch thick doors. The BEST 45H uses a 2-3/4 inch backset and its standard configuration is for 1-3/4 inch doors, with a thick door configuration available up to 5 inches when specified at order. A 2-1/2 inch backset body will not line up with a 2-3/4 inch prep, so these are not interchangeable in an existing mortise pocket.
8) What trim and lever choices do I need to pick for a BEST 45H order?
Three decisions beyond finish and handing. Trim style: H rose, R rose, or J wrought escutcheon. Lever style: 12 solid tube no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, 3 solid tube with return, or 4 round knob. The trim choice also affects your security path, since drill resistant cores are the Grade 1 Security route with escutcheon trims and the 1EK7K4 cylinder is the route with sectional trims.
9) Is there an antimicrobial finish option on the BEST 45H for a hospital or school?
Two of them: 626AM satin chrome and 630AM satin stainless steel, both with the BEST UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST calls it out for healthcare, elderly care, education, transportation, food service and hospitality. If you are standardizing a facility on satin chrome or satin stainless anyway, the AM version is the same look.
10) Is the BEST 45H indicator lock electronic, and what happens in a power outage?
It is entirely mechanical, no electronics and no power. The indicator is a mechanical display driven by the lock, so it reads correctly regardless of building power. If you want an electronic intruder classroom lock instead, the TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID, Grade 1, for 1-3/4 inch doors.
11) Does 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, the accessibility standard for door hardware operation. Pair that with one of the lever styles rather than the 4 round knob if accessible operation is the goal.
12) What is the difference between the BEST 45H and the 47H series?
Security grade. The 45H carries ANSI A156.13 Series 1000 Grade 1 Operation and Strength with Grade 2 Security, and reaches Grade 1 Security only with a drill resistant core or the 1EK7K4 high security cylinder. The 47H is Grade 1 for Operational, Strength and Security outright. If your spec sheet calls for Grade 1 security with no qualifiers, the 47H is the cleaner answer.
13) If the opening does not need an indicator, what simpler Grade 1 mortise lock can I use?
For a classroom opening without status indication, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option. The BEST 45H is the choice when you specifically want the visual keyed indicator with intruder function.
14) Can I use a Schlage PM010 or L0170 in place of the BEST 45H indicator lock?
No. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the L0170 is a half dummy trim, Grade 1 non-keyed mortise lever lock. Neither one locks. The BEST 45H intruder lock is keyed, single cylinder, with a visual keyed indicator, so a passage or dummy unit is not a substitute for it on any opening that has to be secured.
15) What should I use instead of the 45H indicator mortise lock on a restroom or privacy door?
For privacy openings, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a 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 thick. Both share the 45H's mortise format, and the Hager matches its 2-3/4 inch backset. The BEST 45H intruder version is keyed with single cylinder operation, which is a different function than privacy.
16) Is there a mortise lock for a behavioral health opening where the 45H lever trim would not be accepted?
Yes. 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, and the MRX-A-01 is the ligature resistant arch trim passage version. Marks USA also offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. The BEST 45H intruder lock uses conventional lever and knob trim styles including curved, gull wing, contour and round knob, which is why it is specified on standard commercial openings rather than anti-ligature ones.
17) Which mortise lock should I pick if I want RFID credentials on a classroom door rather than keys?
The TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and 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 wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The BEST 45H intruder lock is a non-electronic mechanical lock, so it fits facilities standardizing on keys and small format interchangeable cores rather than credentials.
18) Is a Hager 3850E office mortise lock an equivalent to the BEST 45H indicator lock?
They share the mortise format and the 2-3/4 inch backset, but the functions differ. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, for doors 1-3/4 to 2-1/2 inches thick. The BEST 45H intruder version is keyed, single cylinder, with a visual keyed indicator and an SFIC housing supplied less core. If the door needs key control and a visible locked or unlocked display, the 3850E will not cover it.
19) I need to match existing hardware finishes across a building. What finishes does the BEST 45H come in?
Fourteen: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oxidized satin bronze oil rubbed, 618 bright nickel, 619 satin nickel, 622 flat black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, 630 satin stainless, 630AM satin stainless antimicrobial, and 690 dark bronze. Two behave differently over time: 613 is meant to wear to an antique appearance, and 690 stays a dark brown. If you are matching a fleet of existing doors, those two will not stay identical to a freshly installed unit.
20) Is the BEST 45H mortise lock rated for high traffic corridors and classroom doors?
It is a heavy duty commercial lock, built around a 0.095 inch cold rolled steel case, cover and armored front, zinc dichromate plated for corrosion protection, with a solid one-piece stainless steel anti-friction latchbolt. The hub runs on roller bearings and the trim carries a lever return spring to resist lever droop, which is the usual failure mode on a high cycle corridor door. Case integrity comes from four corner screws plus the interlocking armored front.
21) What mortise lock works for a dormitory or corridor door instead of the intruder indicator function?
The Sargent 7925 is a dormitory exit function mortise lock, Grade 1 heavy duty, with rose trim and a single cylinder deadbolt. The Schlage L9092EU with 03A trim is a heavy duty corridor-function mortise lock, keyed outside, with request to exit and 12/24VDC electric lock/unlock of the outside lever for 1-3/4 inch doors. The BEST 45H intruder lock is a mechanical, non-electronic lock with an SFIC housing supplied less core, so it suits corridor and dormitory openings that are not tied into an access control system.
22) I only need a deadbolt on this door, not a full indicator lockset. What are my options?
For a deadbolt-only mortise application, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, matching the 2-3/4 inch backset of the BEST 45H. The Kaba Ilco 185 Series mortise lock is also a deadbolt function unit and is supplied with no handing. The BEST 45H intruder lock is a complete keyed lockset with lever or knob trim, so it is the choice when the opening needs latching operation as well as locking.
