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 proper backset and faceplate positioning.
  3. Prepare door mortise pocket and drill required holes for cylinder, trim mounting, and through-bolts per manufacturer specifications.
  4. Install case assembly into mortise pocket and secure with provided fasteners, ensuring armored front self-aligns with door bevel during installation.
  5. Install cylinder, trim components, and strike assembly according to manufacturer torque specifications and alignment requirements.
  6. Test device operation to verify proper latch and deadbolt function, lever return, and locking mechanisms. Make final adjustments as needed and refer to manufacturer documentation for complete installation details.

BEST 45H7H15H626 – Frequently Asked Questions

1) Will the BEST 45H mortise lock fit a 2-1/4 inch thick door?
Yes, but you have to order it that way. The standard 45H configuration is built for 1-3/4 inch doors. A thick door configuration covers doors up to 5 inches thick, and the thickness has to be specified at time of order - it isn't a field adjustment. Backset is 2-3/4 inches either way.
2) Does the BEST 45H mortise lock come with a core, or do I need to order one separately?
It ships prepped for a small format interchangeable core, less core. You supply the SFIC core keyed to your system. That's an advantage on a hotel or multi-tenant property since you can pin and swap cores in-house without pulling the lock. Note that a drill resistant core (1CD, 1CDP, 1CDF, or 1CDX) is required with escutcheon trims to reach Grade 1 Security; with sectional trims it's the 1EK7K4 high security cylinder.
3) Is the BEST 45H mortise lock ANSI Grade 1?
The 45H carries ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, with Grade 2 Security as furnished. To get Grade 1 Security you add a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or the 1EK7K4 high security cylinder with sectional trim. If the spec on your drawing calls out Grade 1 across all three categories with no cylinder qualifier, the 47H Series is the one that carries Grade 1 Operational, Strength and Security outright.
4) Will a BEST 45H mortise lock match the other mortise locks already in my building?
If the existing doors are ANSI mortise prepped at a 2-3/4 inch backset for 1-3/4 inch doors, the 45H goes into the same pocket. Where it differs from most brands is the cylinder: it's prepped for BEST small format interchangeable core, so it standardizes with the rest of a BEST keyed system. Locks with fixed mortise cylinders, like a Corbin Russwin ML2000 or a Hager 3800, use a different cylinder format even though the case prep is comparable.
5) Will the BEST 45H latch into my existing ANSI strike?
The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, both solid stainless, and the latch is oil-impregnated for anti-friction operation with roughly 50 percent more contact surface against the strike than a conventional latch. Those throws are standard for an ANSI mortise strike, so an existing ANSI-prepped frame normally takes it. Confirm the strike lip projection clears your frame stop.
6) What is the closest classroom function mortise lock to the BEST 45H?
For a classroom opening, mechanical Grade 1 mortise options include the Corbin Russwin ML2003 classroom lockset from the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors. The Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an ANSI strike and a steel escutcheon measuring 8-1/2 inch H x 2-3/4 inch W x 7/16 inch, which adds a visual locked/unlocked indicator the 45H hotel function does not provide.
7) Is there an electronic or credential-based alternative to the BEST 45H mortise lock for hotel rooms?
The BEST 45H is a mechanical, non-electronic keyed mortise lock. If the property is moving to credentials, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access rated BHMA Grade 2, and the Dormakaba E-Plex E5086 is a Grade 1 back-to-back electronic pushbutton and card mortise lock. The Accentra nexTouch NTM623-NR is a Grade 1 mortise lock with a capacitive touchscreen keypad, no deadbolt, and cylinder override. Choosing electronic changes the door prep and adds power or battery considerations that a mechanical 45H does not require.
8) What is a comparable Grade 1 mortise lock to the BEST 45H if I need a dormitory or corridor function instead of hotel function?
The BEST 45H hotel function lock is a keyed, single-cylinder mortise lock with a 2-3/4 inch backset and rose trim. If the opening calls for a corridor or dormitory function instead, the Sargent 7925 is a Grade 1 heavy duty mortise lock with corridor/dormitory function, rose trim, and a single cylinder deadbolt. Both are rose-trim mortise locks with a deadbolt in the case; the difference is how the outside lever and deadbolt interact, so confirm the function the door schedule specifies before ordering.
9) I need a storeroom function mortise lock, not hotel function. What else should I look at?
The BEST 45H in hotel function is keyed and single cylinder, which is not a storeroom lock. For a storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The NM8080's IC option is worth noting if you are already keying to a small format interchangeable core system, which is what the 45H is prepped for.
10) My door does not need a key at all. What non-keyed mortise lock replaces the BEST 45H?
The 45H hotel function is keyed with a single cylinder, so it is the wrong part for a passage or privacy opening. For passage, the Falcon MA101 is a Grade 1 heavy duty fire rated mortise passage lock with field reversible operation, the Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. For privacy, the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt. The Hager 3810S matches the 45H on both backset and rose trim.
11) The prep in my door is a 2-1/2 inch backset. Will the BEST 45H fit, and what else should I use?
No. The BEST 45H mortise case is built to a 2-3/4 inch backset, so it will not land on a pocket cut for 2-1/2 inch. Baldwin's 6300 series mortise bodies use a 2-1/2 inch backset: the 6301 entry/apartment is offered knob by knob and as the 6301LS lever by lever for doors 1-3/4 inch and over, and the 6310 entry/storeroom is offered knob by knob and as the 6310190RRLS right hand reverse lever by lever for doors 1-3/8 inch and over. Verify the pocket depth and door thickness against the body you pick.
12) What is the difference between the BEST 45H and an anti-ligature mortise lockset for a behavioral health unit?
The 45H is a heavy duty commercial mortise lock with lever and knob trim options including solid tube, curved, gull wing, and round knob styles, none of which are ligature resistant. For behavioral health, TownSteel offers the MRX-A-01 Grade 1 heavy duty passage mortise lockset with satin stainless ligature resistant arch trim and the MRX-L-01 Grade 1 heavy duty anti-ligature lever mortise lockset, both for 1-3/4 inch doors. Marks USA's 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant, ADA compliant, and satin stainless steel. These are passage functions, so they do not key like the 45H.
13) Can I use a Schlage PC10 in place of the BEST 45H?
No. The BEST 45H is a mortise lock, meaning the case drops into a rectangular pocket routed into the door edge. The Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors, which uses a bored cross-hole prep instead. The two preps are not interchangeable without replacing the door or fitting a conversion plate. If you want a mortise-prep passage lock from Schlage, the PM010 Grade 1 non-keyed passage latch mortise lock is the mortise counterpart.
14) Does the BEST 45H work on an access control system, or do I need a different mortise lock?
The 45H is a mechanical lock with no electronic option, so it will not tie into an access control head end on its own. For electrified mortise, the Command Access ML190 is a heavy duty motorized mortise lock with field selectable electrically locked or electrically unlocked operation on 24VDC in a storeroom function, and the Schlage L9092EU with 03A trim is a heavy duty corridor function electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, at 12/24VDC for 1-3/4 inch doors. For wireless rather than wired, the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating.
15) For a school that wants intruder or lockdown capability, is the BEST 45H the right lock?
The 45H is a mechanical hotel function lock, which locks the outside lever by key and is not a lockdown product. For classroom lockdown, the TownSteel FME-2000 is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, and the FME-4000 is a Grade 1 heavy duty electronic intruder classroom mortise lockset with RFID for the same door thickness. Purely mechanical alternatives in classroom function include the Cal-Royal NM8070 and the Corbin Russwin ML2003, both Grade 1 for 1-3/4 inch doors.
16) Do I have to specify handing when ordering a BEST 45H mortise lock?
The latchbolt is reversible 180 degrees without opening the case, the auxiliary bolt is non-handed, and the cylinder retainer is non-handed as well. So a handing change in the field is a quick job rather than a lock swap. The lock face also self-adjusts to the door bevel during installation.
17) Which finish should I pick for a hospital or care facility?
For healthcare, elderly care, food service and similar clean-critical areas, BEST offers two UltraShield antimicrobial coated finishes: 626AM satin chrome and 630AM satin stainless. The coating inhibits bacterial and microbial growth on the hardware surface. Twelve standard finishes are also available, from 605 bright brass through 690 statuary dark bronze, including 613 oil-rubbed bronze (which is meant to wear to an antique look) and 622 matte black.
18) What trim and lever options do I choose from on the BEST 45H rose trim lock?
Three rose styles: H is a 2-3/4 inch flat rose, R is a 2-3/4 inch concave rose, and S is a 3-1/2 inch flat rose. Lever choices are 12 solid tube with no return, 3 solid tube with return, contour with angle return, curved with return, curved without return, and gull wing. A 4 round knob is also offered. Levers with a return are the usual pick where ADA-style trim is specified.
19) I need privacy or classroom function, not hotel. What else is out there in a Grade 1 mortise?
Hotel function is specific to guest room use, so for other openings look at the Cal-Royal NM8440 Grade 1 privacy mortise lockset with deadbolt, the Cal-Royal NM8070 Grade 1 classroom lockset, or the NM8080 storeroom lockset with interchangeable core option, all listed for 1-3/4 inch doors. The Sargent 7925 covers corridor and dormitory function with rose trim and a single cylinder deadbolt. The 45H family itself is offered in other function codes as well.
20) 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 covers door opening hardware operation. Pair it with one of the lever trims rather than the 4 round knob if accessibility is the concern.
21) I only need a deadbolt on the door, not a full lockset. What replaces the BEST 45H?
The BEST 45H combines a 3/4 inch throw stainless latchbolt with a 1 inch throw deadbolt in one case, so it is more lock than a deadbolt-only opening needs. For deadbolt only, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, matching the 45H backset, and the Kaba Ilco 185 Series is a non-handed mortise deadbolt. The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and privacy keypad for doors 1-5/8 inch to 1-7/8 inch if you want keyless.
22) Is the Emtek 3102 Memphis a substitute for the BEST 45H mortise lock?
No. The Emtek 3102 Memphis is a dummy mortise entrance lockset, as are the Emtek 3104 Hamilton, 3106 Manhattan, and 3019 Brisbane. Dummy trim has no latch and no locking mechanism; it is surface-applied for an inactive leaf. The BEST 45H is a keyed, single-cylinder working mortise lock with a stainless latchbolt and deadbolt. If you need non-operating trim on a mortise-style door, the Schlage L0170 is a Grade 1 heavy duty mortise half dummy trim for 1-3/4 inch doors.
23) My doors are 1-5/8 to 1-7/8 inch thick. Is the BEST 45H right, or should I look elsewhere?
The standard BEST 45H configuration is built for 1-3/4 inch doors, with a thick door configuration available up to 5 inch when thickness is specified at order. A 1-5/8 inch door falls outside the standard build. Alarm Lock's Trilogy line is specified for 1-5/8 inch to 1-7/8 inch doors, including the DL2700CR weatherproof Grade 1 classroom mortise lock and the DL3500CR Grade 1 classroom mortise lock with 300 user codes. Those are electronic keypad locks rather than mechanical, so confirm the function and credential type suit the opening.
24) What is the difference between the BEST 45H with rose trim and a mortise lock with escutcheon trim?
The 45H comes with rose trim in three styles: H rose 2-3/4 inch flat, R rose 2-3/4 inch concave, and S rose 3-1/2 inch flat, each covering a small round area around the lever. Escutcheon trim is a tall plate spanning lever and cylinder. Hager offers the same function both ways in the 3800 Series, with the 3810S passage using rose and the 3810E passage using escutcheon, both at a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors; the 3850E office lock also uses escutcheon. Escutcheon is often chosen to cover previous prep marks on a retrofit.
25) I need an office or entrance function mortise lock rather than the BEST 45H hotel function. What should I order?
The Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. The Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, at a 2-3/4 inch backset for 1-3/4 inch to 2-1/2 inch doors, which suits an office that needs push-button style control without a key. Note the 45H is keyed with a single cylinder, so if key control matters the NM8050 is the closer match in intent.
26) Can a Sargent 130KB thumbturn be used with the BEST 45H?
The Sargent 130KB is a standard duty mortise thumbturn for the 8200 Series, and the Sargent 130W is a standard duty mortise thumbturn with round backplate for the 7800 Series. Those are trim components matched to Sargent lock bodies, not to the BEST 45H. The 45H is a complete heavy duty mortise lock supplied with its own rose trim and a small format interchangeable core prep less core, so specify BEST trim and core to match the case.
27) Which mortise lock should I pick for a healthcare corridor where surface cleanliness matters?
The BEST 45H is offered in 626AM satin chrome and 630AM satin stainless with UltraShield antimicrobial protected coating, alongside standard finishes from bright brass through matte black. If the opening instead needs a hands-free push/pull, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel that is ADA compliant, and the TownSteel MRX-A-01 is a Grade 1 heavy duty passage mortise lockset in satin stainless for 1-3/4 inch doors. Both of those are passage, so they give up the keying the 45H provides.
28) How durable is the BEST 45H for a high traffic opening?
Built heavy: 0.095 inch cold rolled steel case, cover and armored front, zinc dichromate plated against corrosion, four corner case cover screws, and an interlocking armored front and cover for lateral strength. The hub runs on roller bearings, which cuts wear and reduces strike wear over the life of the lock. It's a commercial-duty lock, rated heavy duty.
