BEST 45H7R3J626VIN – Frequently Asked Questions

1) Does the BEST 45H classroom lock come with a core, or do I need to buy one separately?
It ships as an SFIC housing less core, so the cylinder core is a separate purchase. You add a BEST small format interchangeable core in your own keyway and keying scheme. That's the point of the SFIC prep, you can key it into an existing BEST system and swap cores later without pulling the lock. One note on the rating: to reach Grade 1 Security you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trims, or the 1EK7K4 high security cylinder with sectional trims.
2) What does the visual indicator on the BEST 45H show, and can you read it from across a classroom?
The indicator uses a padlock icon: open padlock means unlocked, closed padlock with red paint means locked. A teacher keying the outside lever to lockdown can glance at the indicator and confirm the door is secure without opening it and testing the lever. That's the whole reason to spec an indicator lock over a plain classroom function.
3) Do I have to specify handing when ordering a BEST 45H mortise lock?
Handing is a required selection: left hand, right hand, left hand reverse or right hand reverse. That said, the lock case itself is non-handed, the latch reverses by rotating 180 degrees without opening the case, and a four position hub toggle sets the locked/unlocked behavior of each hub. So a field change is straightforward if the opening turns out opposite to what was surveyed.
4) What grade is the BEST 45H mortise lock certified to?
ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, Grade 2 for Security as furnished. Security climbs to Grade 1 when paired with a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) behind escutcheon trim, or the 1EK7K4 high security cylinder with sectional trim. The design also meets the intent of ANSI A117.1 section 404.2.6. If your spec demands Grade 1 across the board including security, the 47H series carries Grade 1 operational, strength and security outright.
5) What else could I use if I want a classroom indicator mortise lock but not from BEST?
The closest cross-brand match is the Marks USA LA318GJ classroom security indicator mortise lockset, Grade 1, for 1-3/4 inch doors, supplied with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches. If you only need standard classroom function without the visual indicator, the Cal-Royal NM8070 and the Corbin Russwin ML2003 are both Grade 1 classroom mortise locksets for 1-3/4 inch doors. The BEST 45H is the one to pick when you are keying into an existing BEST SFIC system, since it comes prepped less core.
6) I need a classroom mortise lock with a keypad instead of a key. What should I use in place of the BEST 45H?
For keypad access, the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 electronic mortise lock with classroom function and weatherproof design for 1-5/8 to 1-7/8 inch doors, and the DL3500CR adds 300 user codes on the same classroom function and door range. The BEST 45H is a non-electronic mechanical lock, so switching to either of these changes the opening from a keyed cylinder to code-based credential management.
7) Can I use a Baldwin 6310 mortise lock body in a door prepped for the BEST 45H?
Check the backset first. The Baldwin 6310 entry/storeroom mortise lock body uses a 2-1/2 inch backset for doors 1-3/8 inch and over, while the BEST 45H uses a 2-3/4 inch backset. That difference moves the cylinder and lever centerline relative to the door edge, so the two are not drop-in interchangeable in the same door prep. The Baldwin 6310 is also an entry/storeroom function rather than classroom.
8) Which trim and lever choices do I need to pick for a BEST 45H, and does the trim style affect the security rating?
Three trim styles: H rose, R rose, and J wrought escutcheon. Seven lever/knob designs: 12 solid tube 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 round knob. Trim style does bear on security, escutcheon trims take the drill resistant core route to Grade 1 security while sectional trims need the 1EK7K4 high security cylinder. All lever trims include a lever return spring in the trim to resist lever droop.
9) Is there an antimicrobial finish option on the BEST 45H for a hospital or school?
Yes, two: 626AM satin chrome and 630AM satin stainless, both with the BEST UltraShield coating that inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it where cleanliness is a priority, so healthcare, elderly care, education, transportation, food service and hospitality. The other twelve finishes run from 605 bright brass through 690 statuary dark bronze. Worth knowing before you standardize a building: 613 oxidized satin bronze is meant to wear to an antique look over time, so it won't stay uniform across a fleet of doors.
10) Does the BEST 45H need power or wiring run to the door?
No. The 45H is a mechanical, non-electronic mortise lock, keyed single cylinder. Nothing to wire, nothing to battery, and it keeps working in a power failure. If your project actually wants credential-based classroom lockdown, the electronic route in this category includes the TownSteel FME-2000 and FME-4000 Grade 1 classroom mortise locksets with RFID, and the Alarm Lock DL3500CR Trilogy Grade 1 classroom keypad lock for 1-5/8 to 1-7/8 inch doors. Note that thickness range, it is narrower than the mechanical 45H window.
11) What exactly does the classroom function do on the BEST 45H, and does the deadbolt throw with the lever?
Classroom function on the 45H: the outside lever is locked and unlocked by key, the inside lever always retracts the latch for free egress. The latchbolt throws 3/4 inch and there is a separate stainless deadbolt with a 1 inch throw. The four position hub toggle is what you set at install to establish which hub is locked and which is free. Combined with the visual indicator, staff can key the outside to locked and read the closed red padlock to confirm it took.
12) What classroom mortise lock should I specify if the school wants credential badges rather than mechanical 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 FME-4000 Series is an electronic intruder classroom mortise lockset with RFID, also heavy duty Grade 1 for 1-3/4 inch doors. Both cover the same classroom function as the BEST 45H but read a card credential, where the 45H is a mechanical keyed lock built for an SFIC core.
13) The door is a storeroom, not a classroom. What takes the place of the BEST 45H there?
For storeroom function in the same mortise format, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. The BEST 45H is built specifically on classroom function, where the outside lever is locked and unlocked by key rather than held permanently locked.
14) Is the Schlage PM010 a substitute for the BEST 45H mortise lock?
No. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, so it latches the door but has no locking or key function at all. The BEST 45H is a keyed single cylinder classroom lock with a visual keyed indicator. If you need a passage opening on the same run of doors, the PM010 or the Hager 3810S Grade 1 passage mortise lock with rose and 2-3/4 inch backset are the right parts; neither replaces a keyed classroom lock.
15) What mortise lock should I use for a restroom or bedroom door instead of the BEST 45H classroom lock?
Privacy function is the correct choice there. 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. Both lock from inside the room without a key, while the BEST 45H is a keyed classroom lock intended for an opening controlled from the corridor side.
16) What is the difference between the BEST 45H and an access-control mortise lock like the Schlage LEMD or Dormakaba Saffire?
The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader, mobile enabled deadbolt with LED and Greenwich trim, rated for 3 hour fire doors; the Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Both are credential-managed openings tied to a system. The BEST 45H is a non-electronic mechanical classroom lock with a visual keyed indicator that operates entirely from the cylinder, with no power, reader, or software behind it.
17) I need the classroom door to be electrically locked and unlocked from the security panel. Is there a mortise lock for that?
Yes, but not in the BEST 45H family, which is a mechanical non-electronic lock. The Command Access ML190 Series is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function, 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 12/24VDC for 1-3/4 inch doors. Both require power to the opening and a wire transfer hinge or loop that the 45H does not.
18) For a dormitory corridor door, should I use the BEST 45H classroom lock or something else?
The Sargent 7925 is a heavy duty Grade 1 dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, which suits a corridor or dormitory opening where the occupant throws a deadbolt from inside. The BEST 45H is classroom function, where the outside lever is locked and unlocked by key from the corridor and the visual indicator shows locked or unlocked status.
19) We need a behavioral health classroom door. Is the BEST 45H the right lock, or is there an anti-ligature option?
For anti-ligature openings, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, and the MRX-A-01 is the same passage function with ligature resistant arch trim in satin stainless steel. The BEST 45H uses conventional lever trim in styles such as curved with return and gull wing, which is not a ligature resistant profile, and it is keyed classroom function rather than passage.
20) How durable is the BEST 45H case for a high traffic school corridor?
Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance. The armored front wraps both the latch and the deadbolt for lateral strength and is a staked assembly that self-aligns during install. Case integrity comes from four corner screws plus the interlocking armored front. The latch itself is solid one-piece stainless with 50 percent more surface contact with the strike, oil impregnated for anti-friction operation, and the hub runs on roller bearings. It is classed heavy duty and commercial.
21) Will an Emtek Memphis or Hamilton mortise lockset work as a replacement for the BEST 45H?
No. The Emtek 3102 Memphis and 3104 Hamilton mortise entrance locksets are dummy function, meaning they mount as fixed trim with no latch operation and no keying. The BEST 45H is a keyed single cylinder classroom mortise lock with a 2-3/4 inch backset. Dummy trim like the Emtek 3106 Manhattan or 3019 Brisbane is used on inactive leaves and closet faces, not on a classroom opening.
