BEST 45H7TD3J626VIB – Frequently Asked Questions

1) What does dormitory function actually do on a BEST 45H mortise lock?
Dormitory function on the 45H means the outside lever is locked or unlocked by key, and the deadbolt is thrown from inside by turn while the inside lever always retracts both bolts for free egress. It is the pattern used for student housing, patient rooms, hotel guest rooms and multi-tenant apartments, where the occupant controls the deadbolt but staff keys the lever. It is a single cylinder keyed lock, so there is one key side.
2) What does the double visual indicator on the BEST 45H show?
Two indicators, one on each side of the door, showing the same thing: an open padlock icon when the lock is unlocked, and a closed padlock icon painted red when it is locked. On a dorm or patient room that means staff in the corridor can read the door status without trying the lever, and the occupant can confirm the deadbolt is thrown before walking away. The icons are graphic, not text, so no language issue in a mixed-occupancy building.
3) Does the BEST 45H mortise lock come with a core, and what cylinder does it take?
The 45H ships with an SFIC housing prepped less core, so a BEST small format interchangeable core is ordered separately and keyed to your system. A cylinder security screw keeps the cylinder from being pulled without first removing the core, and solid machined cylinder rings with a wavy washer resist wrenching. Worth knowing for spec: with escutcheon trim the lock hits ANSI A156.13 Grade 2 Security as supplied, and a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) is what raises it to Grade 1 Security.
4) Will the BEST 45H latch into the strike that is already in my frame?
The latchbolt is solid one-piece stainless with a 3/4 inch throw and the deadbolt throws 1 inch, so the frame needs a strike prepped for both a latch and a deadbolt at a 2-3/4 inch backset mortise layout. The latch is engineered with 50 percent more surface contact with the strike than a conventional one, so an existing strike lip that is worn or shallow is the thing to check. If the frame currently carries a latch-only mortise strike, it needs to be replaced with a full mortise strike package.
5) I need an indicator mortise lock for classrooms, not dorm rooms. Is the BEST 45H dormitory the right one?
No. Dormitory function locks and unlocks the outside lever by key with an occupant-controlled deadbolt, which is not classroom security behavior. For a classroom security indicator lockset, the Marks USA LA318GJ is the one to look at: Grade 1, classroom security indicator function, ANSI strike, steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches, for 1-3/4 inch doors. If you want the same indicator idea in a plain classroom mortise lock without indication, the Corbin Russwin ML2003 and Cal-Royal NM8070 are both Grade 1 classroom mortise locksets for 1-3/4 inch doors.
6) I am standardizing apartment and dorm doors on one lock across a portfolio. What do I have to specify on each BEST 45H order?
Four things per opening: handing (left, right, left hand reverse or right hand reverse), finish from the fourteen offered, lever or knob style, and trim style (H rose, R rose or J wrought escutcheon). If any door is thicker than 1-3/4 inches, the thickness has to be stated so the thick door configuration ships instead of the standard one, which covers up to 5 inches. Cores are separate, since the lock arrives with an SFIC housing less core. Backset is fixed at 2-3/4 inches on every one, so the door prep is the same across the building.
7) What is the closest cross-brand equivalent to a BEST 45H dormitory function mortise lock?
The Sargent 7925 is the nearest peer: a 7900 Series heavy duty Grade 1 mortise lock with corridor/dormitory function, rose trim, and a single cylinder deadbolt. The BEST 45H is likewise a heavy duty commercial mortise lock with dormitory function, on a 2-3/4 inch backset, and it carries a double visual indicator that shows a padlock icon open when unlocked and a red padlock icon closed when locked. If the opening needs the occupant to see lock status at a glance, that indicator is the difference between the two; if it does not, the 7925 covers the same corridor/dormitory operation.
8) What do I use instead of a BEST 45H if the dorm rooms are moving to card or code access?
Several electrified mortise options cover that. The Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back to back configuration. The Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile enabled deadbolt with LED, Greenwich trim, right hand, with a 3 hour fire rating. The Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. The BEST 45H is a non-electronic mechanical lock prepped for a small format interchangeable core less core, so switching to any of these changes the credential system and, on the wireless units, adds a power and network path to plan for.
9) Is a Baldwin 6301 or 6310 mortise lock body a drop-in for a BEST 45H?
No. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies are built on a 2-1/2 inch backset, offered knob by knob or lever by lever, while the BEST 45H uses a 2-3/4 inch backset. That quarter inch moves the cylinder and knob or lever centerline relative to the door edge, so the existing mortise pocket and face prep will not line up without rework. If the door is already prepped for the 45H's 2-3/4 inch backset, stay with a 2-3/4 inch backset lock.
10) Behavioral health rooms need anti-ligature trim. Is there an alternative to the BEST 45H lever and escutcheon trim?
Yes. 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 satin stainless ligature resistant arch trim version of the same passage lockset. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel, ligature resistant and ADA compliant. The BEST 45H is offered with H rose, R rose, and J wrought escutcheon trim and lever styles including curved with return, contour with angle return, gull wing, and a round knob, which are conventional trims rather than ligature resistant ones. Note the TownSteel and Marks options listed here are passage function, so a keyed opening still needs the 45H or another keyed lock.
11) The dorm doors are thicker than 1-3/4 inches. Which mortise locks can handle that?
The BEST 45H standard configuration is built for 1-3/4 inch doors, with a thick door configuration available for doors up to 5 inches when the thickness is specified at time of order. Among the peers, the Hager 3810E and 3810S passage mortise locks are listed for doors 1-3/4 to 2-1/2 inches, and the Baldwin 6310 entry/storeroom body is listed for 1-3/8 inch and over. Several others, including the Cal-Royal NM8070 classroom and Corbin Russwin ML2003 classroom locksets, are listed at 1-3/4 inch. For a heavy thick-door opening that still needs to be keyed, the 45H thick door configuration reaches further than the others.
12) What faceplate size does the BEST 45H mortise lock use and does it need beveling for my door edge?
The faceplate measures 8 x 1-1/4 x 1/16 inches, available in stainless steel, brass or bronze material. No beveling work is needed: the armored front self-aligns with the door bevel as the lock is installed, and the trim is self-aligning as well. If you are replacing another mortise lock, that 8 by 1-1/4 inch footprint is what has to match the existing edge cutout.
13) Which trim and lever do I pick for a BEST 45H, and does it matter for the security grade?
Three trim styles are offered, H rose, R rose and J wrought escutcheon, with seven lever and knob options: 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 choice does affect security: with escutcheon trim, Grade 1 Security requires a drill resistant core (1CD, 1CDP, 1CDF or 1CDX), while sectional trims need the 1EK7K4 high security cylinder to reach it. Pick the trim style first if you are matching other openings in the building, then the lever.
14) Is there an antimicrobial finish option for a BEST 45H going into a hospital or care facility?
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 calls those out for hospital and healthcare, elderly care, education, transportation, food service and hospitality work. Standard finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed bronze, 618 bright nickel, 619 satin nickel, 622 flat black, 625 bright chrome, 626 satin chrome, 630 satin stainless and 690 dark bronze. Note that 613 is meant to wear to an antique appearance over time, so it is not a match for openings that have to stay uniform.
15) Is the BEST 45H mortise lock electronic or does it need wiring?
Purely mechanical, no power and no wiring. It is a keyed mortise lock with a hub-driven lever and a thumbturn deadbolt, so it keeps working through a power outage with no fail-safe or fail-secure decision to make. If the opening actually needs access control, the electrified mortise options include the Command Access ML190 Series motorized lock with field selectable EL/EU operation on 24VDC, and the Schlage L9092EU with keyed outside lever and request-to-exit on 12/24VDC for 1-3/4 inch doors.
16) How durable is the BEST 45H lock case for a high traffic dorm or apartment corridor?
Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance, and the hub runs on a roller bearing mechanism for wear resistance across cycles. The latch is solid one-piece stainless, oil impregnated for anti-friction operation, with a precision curve for cycle life. The whole thing is certified to ANSI A156.13 Series 1000 Grade 1 Operation and Strength, which is the top commercial durability tier for a mortise lock.
17) 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, which is the door hardware operation clause. Lever styles that support that include 3 and 12 solid tube, 14 curved with return, 15 contour with angle return, 16 curved without return and 17 gull wing. The 4 round knob is also offered, and a round knob is generally not the choice where accessible operation is required.
18) Do I need to order the BEST 45H by hand, and are there non-handed mortise locks if I am not sure of the swing?
The 45H is ordered by door hand in left hand, right hand, left hand reverse, or right hand reverse, though its latch is reversible and rotates 180 degrees without opening the case and the cylinder retainer is non-handed. If the swing is genuinely unknown at order time, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation, and the Kaba Ilco 185 Series mortise lock is supplied with no handing. Note that both of those are passage and deadbolt functions rather than a keyed dormitory lock, so they are alternatives for the opening, not for the 45H's function.
19) Can a Cal-Royal NM8080 or NM8050 replace a BEST 45H dormitory mortise lock?
Not on a like-for-like basis. The Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option, and the NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch; both are listed for 1-3/4 inch doors. The BEST 45H is dormitory function with a double visual indicator, so it locks and shows status differently at the door. Where the opening only needs an always-locked storeroom outside lever, the NM8080 is the closer fit; where it needs the dormitory sequence and a visible locked/unlocked icon, the 45H is what the spec calls for.
20) What is a simpler mortise lock than the BEST 45H when the opening does not need to be keyed?
For a non-keyed opening, the Hager 3810S is a Grade 1 passage mortise lock with rose trim on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches, and the 3810E is the same passage lock with escutcheon trim. Schlage PM010 is another Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. The BEST 45H is keyed, single cylinder, and prepped for a small format interchangeable core less core, so it carries key control and indicator hardware a passage opening has no use for. Both Hager options share the 45H's 2-3/4 inch backset, so the door mortise and strike location match.
21) Our patient rooms and restrooms need occupied status at the door. Is the BEST 45H the right lock, or is there a privacy alternative?
They are different jobs. The BEST 45H is dormitory function, keyed single cylinder with a double visual indicator reading locked or unlocked, and it is offered in 626AM satin chrome and 630AM satin stainless antimicrobial finishes for healthcare and elderly care use. For a true privacy opening, 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 on a 2-3/4 inch backset for doors 1-3/4 to 2 inches. Use the privacy locks on bath and exam doors and the 45H where the room is keyed and the occupant needs to see whether it is secured.
22) What looks like a substitute for the BEST 45H mortise lock but will not actually operate a door?
Watch for dummy and trim-only items. The Schlage L0170 is a Grade 1 half dummy trim, non-keyed, for 1-3/4 inch doors; the Emtek 3102 Memphis, 3104 Hamilton, and 3106 Manhattan are dummy mortise entrance locksets; and the Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices. Also in that group are the Sargent 130KB and 130W mortise thumbturns, which are trim components rather than lock bodies. The BEST 45H is a complete keyed mortise lock with a 3/4 inch throw stainless latchbolt and a 1 inch throw stainless deadbolt, so none of those pieces will latch or secure the opening on their own.
23) Can I just add a mortise deadbolt instead of specifying a BEST 45H dormitory lock?
A deadbolt alone changes what the door does. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. Neither carries a latch or lever, so the door has no latching or free egress hardware of its own. The BEST 45H combines a keyed single cylinder dormitory lock with a 3/4 inch throw latchbolt and a 1 inch throw deadbolt in one case, on the same 2-3/4 inch backset as the Sargent 4874, and adds the visual indicator. Specify the deadbolt only where separate lever or push-pull hardware is already handling the latch.
24) Which mortise locks besides the BEST 45H work with an interchangeable core keying system?
The BEST 45H ships with a small format interchangeable core prep, less core, so the core drops into an existing SFIC master key system. Among comparable mortise locks, the Cal-Royal NM8080 heavy duty Grade 1 storeroom lockset is offered with an interchangeable core option, and the Accentra NTM623-NR nexTouch mortise lock includes a cylinder override that accepts a keyed cylinder alongside its touchscreen keypad. For a facility standardizing on one key system across dorm, storeroom, and keypad openings, those are the peers to line up against the 45H.
25) What is the difference between the BEST 45H and an electrified mortise lock like the Command Access ML190 or Schlage L9092EU for access control tie-in?
The Command Access ML190 Series is a heavy duty motorized mortise lock with field selectable electrically locked or electrically unlocked operation on 24VDC, in storeroom function. The Schlage 03A electric lock/unlock outside lever mortise lock is heavy duty corridor function, keyed outside, with request to exit and 12/24VDC operation, for 1-3/4 inch doors. Both need power run to the door and coordination with an access control panel. The BEST 45H is a mechanical, non-electronic dormitory lock with a double visual indicator, so it secures and reports status at the door itself with no wiring, transfer hinge, or panel input.
