Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness (standard 1-3/4" or up to 5" thick door configuration), mortise pocket dimensions, and handing requirements.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces for the 8" H x 1-1/4" W faceplate.
  3. Prepare door mortise pocket and frame strike pocket according to specifications, ensuring proper clearance for the 1" throw deadbolt and 3/4" throw latchbolt.
  4. Install lock case into mortise pocket and secure with provided screws, allowing the armored front to self-align with door bevel during installation.
  5. Configure the four position hub toggle to determine locked/unlocked operation for each hub based on application requirements and install escutcheon trim with self-aligning mechanism.
  6. Test lock operation including visual indicator function, latch and deadbolt throw, and lever return to horizontal position. Refer to manufacturer documentation for complete installation details and troubleshooting.

BEST 45H7TD3J626VIN – Frequently Asked Questions

1) Do I have to order the BEST 45H handed, or can it be reversed in the field?
The lock body is non-handed. The latch reverses by rotating 180 degrees and you do not have to open the case to do it, and the hub uses a four position toggle so each side can be set locked or unlocked to suit the application. Hand still gets specified on the order (left, right, left hand reverse, right hand reverse) because the trim and lever orientation follow the door, but the case itself is not a handing mistake you can't undo on site.
2) What does dormitory function TD mean on a mortise lock, and is it the right function for a dorm or apartment corridor door?
Dormitory function means the outside lever is locked or unlocked by key, and turning the inside lever retracts both the latch and the deadbolt for free egress. That is the function for a student room, an apartment corridor door, or a guest room: occupant secures the door from inside with the thumbturn or key, staff gets in with a key, and nobody is ever trapped behind the deadbolt. If instead you want the outside lever permanently locked with key-only entry and no deadbolt in play, storeroom is the function to spec, not dormitory.
3) Does the BEST 45H come with a cylinder, or do I have to supply my own core?
It ships with SFIC housing, less core. No core is included, so you supply a small format interchangeable core in your keyway to bring it into an existing master key system. That is what most institutions want, since you can pin and swap cores in house without pulling the lock. It is single cylinder, so one keyed side.
4) What ANSI grade is the BEST 45H mortise lock, and how do I get it to Grade 1 security?
The 45H is ANSI A156.13, Series 1000, Grade 1 for operation and strength, Grade 2 for security. To reach Grade 1 security you have to change the core: with escutcheon trim, use a drill resistant core (1CD, 1CDP, 1CDF or 1CDX); with sectional trim, use the 1EK7K4 high security cylinder. If your spec sheet says Grade 1 security across the board, that core selection is not optional. The design also meets the intent of ANSI A117.1 section 404.2.6.
5) What do I need to specify when ordering a BEST 45H mortise lock?
Five things decide the part: function (TD is dormitory), door hand (left, right, left hand reverse or right hand reverse), trim style (H rose, R rose, or J wrought escutcheon), lever or knob style, and finish. Lever choices run 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, and 4 round knob. If the door is thicker than 1-3/4 inches, that thickness gets called out too, and you order the core separately.
6) What is the closest equivalent to a BEST 45H dormitory mortise lock from another manufacturer?
The Sargent 7925 is the nearest peer: a 7900 Series heavy duty Grade 1 mortise lock in corridor/dormitory function with rose trim and a single cylinder deadbolt. Both are heavy duty Grade 1 mortise locks that give a dormitory-style opening a keyed outside lever plus a deadbolt. The BEST 45H carries a visual keyed indicator that shows a padlock icon open for unlocked and closed with red paint for locked, and it ships with SFIC prep less core so it drops into an existing small format interchangeable core master key system. The Sargent 7925 is specified with rose trim, while the 45H can be ordered with H rose, R rose, or J wrought escutcheon.
7) What mortise lock should I use if the room needs classroom function instead of dormitory?
For a classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. The BEST 45H covered here is built for dormitory function, where the outside lever is locked or unlocked by key and the deadbolt is thrown from the inside. Classroom function instead keys the outside lever from the corridor side without a deadbolt, which is what most school and campus code reviews call for on a teaching space.
8) What is the electronic equivalent if I want to manage dorm room access by credential instead of key?
Several mortise locks in the same door prep carry credentials instead of a key. The Schlage Electronics 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, and carries a 3 hour fire rating. The Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card back to back mortise lock, and the Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad and cylinder override. The BEST 45H is a mechanical lock with no electronics, using SFIC prep less core for key control, and its visual indicator shows status at the door rather than reporting it to a system.
9) Is a Baldwin 6301 or 6310 mortise lock body a drop-in replacement for a BEST 45H?
Not in the same prep. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies are built to a 2-1/2 inch backset, available knob by knob or lever by lever, with the 6301 for doors 1-3/4 inch and over and the 6310 for doors 1-3/8 inch and over. The BEST 45H uses a 2-3/4 inch backset, so the lever or knob centerline sits a quarter inch further from the door edge and the existing mortise pocket and trim holes will not line up. Confirm the backset on the door before ordering either one.
10) What mortise lock fits a door thinner than 1-3/4 inch or an aluminum storefront?
The BEST 45H standard configuration is built for 1-3/4 inch doors, with a thick door configuration available up to 5 inches when specified at order. For thinner or narrower openings, the Marks USA 21AC and 22AC ornamental iron mortise locks are entrance double cylinder locks with round knob built for 1 inch doors. On aluminum storefront, the Dormakaba E-Plex 2066 is a wide stile electronic pushbutton keyless mortise lock and the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad made for Adams Rite deadlatches. Measure the door thickness and stile width before choosing, because a 1-3/4 inch mortise case will not go into a 1 inch iron door.
11) What mortise lock should I specify if the opening needs to be released from an access control panel?
For an electrified opening, the Command Access ML190 is a heavy duty motorized mortise lock in storeroom function with field selectable electrically locked or electrically unlocked operation on 24VDC, and the Schlage 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 electronics; it holds its dormitory function through the four position hub toggle and the key, and cannot be released remotely.
12) How does the visual indicator on the BEST 45H show whether the door is locked?
The indicator uses a padlock icon: open padlock for unlocked, closed padlock with red paint for locked. It reads off the key side, so an RA or a nurse walking a corridor can see the status of a room without touching the lever or fumbling a key. That is the whole reason to pay for the indicator version over a plain 45H dormitory lock.
13) Which BEST 45H finish should I pick to match the other doors in my building?
Fourteen finishes are offered, so matching an existing opening is usually possible: 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, 630 satin stainless, 690 dark bronze, plus 626AM and 630AM antimicrobial versions. Two behave differently over time and you should know that before standardizing a corridor: 613 is meant to wear to an antique look, and 690 stays a dark brown. 626 and 630 are the usual institutional picks.
14) Is a mortise lock like the BEST 45H the right choice, or should I use a cylindrical lock?
A mortise lock needs a pocket cut into the edge of the door, which means a heavier prep than a cylindrical lock's two bored holes, but you get a 1 inch deadbolt and a 3/4 inch latchbolt in one case and far higher cycle life. Go mortise when the door is already prepped for it, when you need a deadbolt integrated with the latch as dormitory function requires, or on high traffic institutional openings. If the door has a standard bored prep and you just need a keyed or passage lever, a cylindrical unit like the Schlage PC10 is the simpler fit and does not require re-prepping the door.
15) I need a mortise lock with a status indicator but for a classroom, not a dorm room. What should I look at?
Dormitory function on the 45H locks and unlocks the outside lever by key with the deadbolt tied to inside lever egress, which is a resident room arrangement, not lockdown. For a classroom security opening with an indicator, the Marks USA LA318GJ is the Grade 1 classroom security indicator mortise lockset, for 1-3/4 inch doors, with an ANSI strike and a steel escutcheon measuring 8-1/2 x 2-3/4 x 7/16 inches. BEST also builds the 45H family in other functions, so if you want to stay on BEST SFIC cores, order the classroom function of the series rather than TD.
16) Does the BEST 45H work with a card reader or keypad access control?
No. The 45H is a mechanical lock with no electronics, so there is no reader, keypad or wiring to it. If you need credential based access on a mortise prep, look at electronic mortise locks instead: the Dormakaba LX-I-M002 Saffire is RFID with BLE mobile access, the Schlage LEMD-GRW is a Grade 1 wireless mortise lock with a 125kHz proximity reader, and the TownSteel FME-2000 is a Grade 1 RFID mortise lockset for 1-3/4 inch doors. The tradeoff is that those bring batteries, credentials and a management system into the picture, where the 45H just needs a key.
17) Do I get the strike with the BEST 45H, and what else do I need to complete the install?
Plan on three things beyond the lock case: the SFIC core in your keyway (the housing ships less core), the trim in the style and finish you want, and the strike, which BEST spec's as a separate strike package. Templates come with the lock for marking the door and frame. If the frame is already prepped for a standard ANSI mortise strike, confirm the pocket clears the 1 inch deadbolt throw before you cut anything new.
18) Should I order rose trim or escutcheon trim on the BEST 45H?
Three trim options: H rose, R rose, or J wrought escutcheon. Roses are the cleaner, smaller footprint and cover less of the door face. The escutcheon matters for one practical reason on this lock: the drill resistant core route to Grade 1 security (1CD, 1CDP, 1CDF or 1CDX) applies to escutcheon trims, while sectional trims take the 1EK7K4 high security cylinder instead. So if a security grade is written into your spec, trim choice and core choice have to be decided together, not separately.
19) What is a simpler mortise lock for a door that does not need to be keyed?
For a non-keyed opening, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating, and the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors. Hager also builds the 3810S 3800 Series Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. The BEST 45H is a keyed single cylinder lock with SFIC prep less core, so if the closet or corridor door only needs latching and no key control, a passage mortise body removes the core and the keying from the order entirely.
20) What Grade 1 mortise lock works for an office or entrance door rather than a dorm room?
For an office or entrance opening, the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E 3800 Series is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, with a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. For a straight storeroom opening where the lever is always locked, the Accentra 8805FL is an 8800 Series Grade 1 storeroom mortise lock with an Arcadia lever and the Cal-Royal NM8080 is a Grade 1 storeroom lockset with an interchangeable core option. The BEST 45H TD is dormitory function, keyed single cylinder, which puts key control and a deadbolt on a resident entry.
21) Can I use an Emtek mortise entrance lockset in place of a BEST 45H?
No. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets are all dummy function, meaning the trim is fixed and there is no working latch or lock mechanism behind it - they are used on an inactive leaf or a pull side. The BEST 45H is a keyed single cylinder dormitory function mortise lock with a 3/4 inch throw latchbolt and a 1 inch throw deadbolt. If the door must latch and lock, a dummy set will not substitute regardless of how similar the escutcheon looks.
22) Is a Sargent 4874 mortise deadbolt a substitute for a BEST 45H mortise lock?
No. The Sargent 4874 is a 4870 Series double cylinder mortise deadbolt with a 2-3/4 inch backset - it throws a bolt by key from both sides and has no latch and no lever. Likewise the Kaba Ilco 185 Series is a deadbolt function mortise lock with no handing. The BEST 45H shares the 2-3/4 inch backset but is a complete lockset: a reversible latchbolt, a deadbolt, and lever or knob trim in seven styles from solid tube to gull wing to round knob. A deadbolt body alone leaves the door with nothing to hold it closed.
23) What mortise lock should I use on a behavioral health or ligature resistant opening instead of a lever lock?
For a ligature resistant opening, TownSteel builds the MRX-A-01, a heavy duty Grade 1 satin stainless steel ligature resistant arch trim mortise lockset in passage function for 1-3/4 inch doors, and the MRX-L-01, a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel. Marks USA offers the 5PDN, a Grade 1 hospital passage mortise push/pull paddleset in the 195 Series that is ligature resistant, ADA compliant, and satin stainless steel. The BEST 45H uses conventional lever or knob trim, which is not an anti-ligature profile, though it is offered in 630AM satin stainless steel with UltraShield antimicrobial coating for clinical settings.
24) Which mortise locks are rated for a fire door if the BEST 45H is going on a rated opening?
Among comparable mortise products, the Falcon MA101 Grade 1 heavy duty passage lock carries a fire rating, the Schlage Electronics LEMD-GRW ENGAGE Series Grade 1 wireless mortise lock carries a 3 hour fire rating, and the Schlage Electronics LEBMB-ADD mobile enabled mortise lock is Grade 2 with a 3 hour fire rating. The BEST 45H meets ANSI A156.13 Series 1000 Grade 1 Operation and Strength with Grade 2 Security; Grade 1 Security requires a drill resistant core (1CD, 1CDP, 1CDF, or 1CDX) with escutcheon trims, or the 1EK7K4 high security cylinder with sectional trims. Confirm the label requirements on the opening with your AHJ.
25) Is the antimicrobial finish on the BEST 45H worth specifying for a hospital or a school?
The AM finishes, 626AM satin chrome and 630AM satin stainless, carry the UltraShield coating, which inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends it where cleanliness is a priority: hospital and healthcare, elderly care, education, transportation, food service, hospitality. It is a coating on the lever and trim, not a change to the lock mechanism, so specifying it does not alter fit or function.
26) How durable is the BEST 45H lock case for a high traffic corridor?
Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion protection. The armored front wraps the latch and deadbolt for lateral strength, the latch is solid one piece stainless steel with roughly 50 percent more surface contact with the strike, and it runs on a roller bearing mechanism. The lever return spring sits in the trim rather than the case, which is what keeps levers from drooping on doors that get used hundreds of times a day. It is rated Grade 1 for operation and strength.
27) What is a lighter duty mortise latch option for an interior door that does not need commercial grade hardware?
The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 Series with a brushed steel finish, and the Dormakaba Saffire LX-I-M002 is a BHMA Grade 2 electronic RFID mortise lockset with BLE mobile access. The BEST 45H is a heavy duty commercial lock with a case, cover, and armored front in 0.095 inch cold rolled steel, zinc dichromate plated, rated ANSI A156.13 Grade 1 for operation and strength. On a low traffic interior door where a Grade 1 mortise body is more than the opening calls for, the lighter units cover the same basic function with a smaller prep.
