BEST 45H7T3M611VIT – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a door thicker than 1-3/4 inches?
Standard 45H lock configuration is built for 1-3/4 inch doors. For anything thicker, BEST offers a thick door configuration covering doors up to 5 inches, and you have to state the actual door thickness when you place the order. It is not a field adjustment, so measure the leaf before ordering.
2) What does dormitory function mean on the BEST 45H, and where is it used?
Dormitory function means the door secures from the inside by thumbturn while still being key-operated from the corridor side. The 45H is a single-cylinder keyed lock, so one key cylinder on the outside plus the inside thumbturn. It is the usual choice for student housing, patient rooms, hotel guest rooms and multi-tenant apartments where the occupant wants to lock themselves in without a key.
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 latch is reversible and rotates 180 degrees, so handing can be changed in the field without opening the case, and the cylinder retainer is non-handed. The auxiliary bolt is non-handed as well.
4) Does the BEST 45H come with a cylinder core?
No core is included. The 45H ships with SFIC prep less core, so you supply and install your own BEST-format small format interchangeable core to key it into your existing system. Plan on ordering cores separately.
5) What ANSI grade is the BEST 45H mortise lock?
ANSI A156.13, Series 1000, Grade 1 Operation and Strength, Grade 2 Security. 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. The design also meets the intent of ANSI A117.1 section 404.2.6.
6) What is the closest equivalent to the BEST 45H dormitory mortise lock from another manufacturer?
The Sargent 7925 is the nearest peer: a heavy duty Grade 1 mortise lock with a corridor/dormitory function, rose trim, and a single cylinder deadbolt. The BEST 45H dormitory lock is also a heavy duty commercial mortise lock with a single cylinder keyed function, and it adds a visual thumbturn indicator plus a choice of H rose, R rose, J wrought escutcheon, or M forged escutcheon trim. If the opening needs the occupied/vacant status read at the door, the 45H carries the indicator; if plain rose-trim dormitory hardware is all the spec calls for, the 7925 covers it.
7) Will a Baldwin 6301 or 6310 mortise lock body drop into the same prep as a BEST 45H?
No. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies use a 2-1/2 inch backset, while the BEST 45H is a 2-3/4 inch backset lock. The cross-bore and mortise pocket locations differ, so the door has to be prepped for whichever one you choose. The Baldwin bodies are offered knob by knob and lever by lever, including the 6310190RRLS right hand reverse lever version, for doors 1-3/8 inch and over in the 6310 and 1-3/4 inch and over in the 6301.
8) For a behavioral health room, can I use the 45H indicator lock or do I need anti-ligature trim?
The BEST 45H dormitory lock uses conventional lever styles including curved, gull wing, and round knob, which present a catch point. For ligature-resistant openings, TownSteel offers the MRX-L-01 Grade 1 heavy duty anti-ligature lever mortise lockset and the MRX-A-01 with satin stainless ligature resistant arch trim, both passage function for 1-3/4 inch doors, and Marks USA lists the 5PDN Grade 1 hospital passage push/pull paddleset that is ligature resistant and ADA compliant. Those are passage function, so they do not provide the keyed control or status indication the 45H gives.
9) What does the visual indicator on the 45H thumbturn actually show?
The indicator reads as a padlock icon: open padlock when the door is unlocked, closed padlock painted red when it is locked. That gives housing or facility staff a status read from the corridor without trying the lever. Both single-indicator (T) and double-indicator (TD) escutcheon versions are built in this dormitory function.
10) Which trim and lever choices do I need to pick for a 45H order?
Three choices beyond finish and handing. Trim style: H rose, R rose, J wrought escutcheon or M forged escutcheon. Lever style: 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, or 4 round knob. Note the security tie-in: escutcheon trims take drill resistant cores for Grade 1 security, sectional trims take the 1EK7K4 cylinder.
11) Is there an antimicrobial version of the BEST 45H for healthcare doors?
Two finishes carry the BEST UltraShield antimicrobial coating: 626AM satin chrome and 630AM satin stainless. The coating inhibits growth of bacteria and other microbes on the hardware surface, and BEST recommends it for hospital, elderly care, education, transportation, food service and hospitality openings.
12) How does the BEST 45H compare to a Sargent 7925 dormitory mortise lock?
Both are Grade 1 heavy duty dormitory mortise locks. The Sargent 7925 is a 7900 Series corridor/dormitory lock with rose trim and a single cylinder deadbolt. The BEST 45H differs in that it adds a visual thumbturn indicator showing locked or unlocked status, and it comes prepped for a small format interchangeable core with no core supplied, which matters if you are keying into an existing BEST SFIC system.
13) Can I get the BEST 45H with electronic access control?
No, the 45H is a mechanical mortise lock with no electronic option. If the opening needs credential or keypad access in a mortise prep, the TownSteel FME-2000 Series is a Grade 1 heavy duty RFID mortise lockset for 1-3/4 inch doors, and the Schlage CO-100 is a Grade 1 standalone electronic mortise lock with a keypad reader for 1-3/4 inch doors.
14) The opening does not need to be keyed at all. What mortise lock should I order instead of the 45H?
The BEST 45H dormitory lock is keyed and takes an SFIC housing less core, so it only makes sense where credentials are issued. For a non-keyed opening, the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock that is field reversible and fire rated. Hager also lists the 3810S passage mortise lock with rose and a 2-3/4 inch backset, which matches the 45H backset if you are keeping the same door prep across a run of doors.
15) Is a Sargent 130KB or 130W thumbturn a substitute for the 45H visual thumbturn indicator?
No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 series and the 130W is a standard duty mortise thumbturn with a round backplate in the 7800 series - both are trim pieces, not locks. The BEST 45H dormitory lock is a complete heavy duty mortise lock body with lever or knob trim and an SFIC cylinder prep, where the thumbturn also displays locked and unlocked status. Order a 130KB or 130W only to replace a thumbturn on Sargent hardware already in the door.
16) We want keypad or credential access on the dorm doors instead of mechanical keys. What mortise locks cover that?
The BEST 45H is a non-electronic mechanical mortise lock. For credential-based access in the same mortise prep, the Alarm Lock DL3500CR is a Grade 1 electronic Trilogy mortise lock with 300 user codes and classroom function for 1-5/8 to 1-7/8 inch doors, the Dormakaba E-Plex 5086 is a Grade 1 electronic pushbutton and card mortise lock in a back-to-back configuration, and the Schlage CO-100-MS-40-KP is a Grade 1 standalone electronic mortise lock with a keypad reader and privacy function for 1-3/4 inch doors. Note the Alarm Lock door thickness range is narrower than the 1-3/4 inch standard the 45H is built around.
17) For a bathroom or bedroom door in the same building, is there a simpler mortise lock than the 45H dormitory?
Yes. The Cal-Royal NM8440 is a 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 1-3/4 to 2 inch doors. Both are privacy/bed/bath function with no cylinder, whereas the BEST 45H dormitory lock is keyed with an SFIC prep and carries the visual indicator on the thumbturn. The Hager 3840S shares the 45H 2-3/4 inch backset if you want one door prep across both lock types.
18) What is the difference between ordering a BEST 45H dormitory lock and a storeroom function mortise lock like the Accentra 8805FL?
The Accentra 8805FL is a Grade 1 storeroom function mortise lock in the 8800 series with an Arcadia lever; storeroom keeps the outside lever locked at all times and releases only by key. Cal-Royal's NM8080 is another Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. The BEST 45H dormitory lock instead lets the occupant secure the door from inside with the thumbturn, and the indicator shows whether it is locked. Choose storeroom for closets and mechanical rooms, dormitory for occupied rooms.
19) We need the dorm doors electrically controlled from an access panel. What replaces the mechanical 45H?
The Command Access ML190 series is a heavy-duty motorized mortise lock with field selectable fail-safe or fail-secure operation on 24VDC, storeroom function. Schlage's L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, running on 12 or 24VDC for 1-3/4 inch doors. The BEST 45H is a mechanical lock with no electrical option, so an electrified body is required for panel control.
20) Which mortise locks besides the BEST 45H are made for an SFIC or interchangeable core keying system?
The BEST 45H ships with an SFIC housing less core, so you supply the core from your existing system. Among comparable heavy duty mortise locksets, the Cal-Royal NM8080 Grade 1 storeroom lock is offered with an interchangeable core option for 1-3/4 inch doors. If you are standardizing a building on one core format, those two keep the dormitory and storeroom openings on the same cylinder program.
21) What finishes can I get to match the rest of the doors in my building?
Fourteen options on the 45H: 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 and 630AM antimicrobial, 630 satin stainless, 690 dark bronze. Two age on purpose: 613 wears to an antique look, and 690 stays a dark brown over time.
22) Is a Sargent 4874 mortise deadbolt an alternative to the 45H dormitory lock?
Only if the opening already has a separate latch. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 series - deadbolt only, keyed both sides, no lever and no latchbolt. The BEST 45H dormitory lock is a single cylinder keyed mortise lock with lever or knob trim and an indicating thumbturn, so it handles latching and locking in one body. The Kaba Ilco 185 series is another deadbolt-function mortise lock rather than a lockset.
23) What is the Corbin Russwin ML2003 compared to the BEST 45H dormitory lock?
The Corbin Russwin ML2003 is a Grade 1 classroom function mortise lockset in the ML2000 series for 1-3/4 inch doors. Classroom function locks and unlocks the outside lever by key from the corridor side. The BEST 45H dormitory lock instead locks from the inside thumbturn and reports its state on the visual indicator, which is what student housing and patient rooms generally call for.
