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), stile width, and handing as applicable to this mortise lock.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces for proper mortise preparation.
  3. Prepare door and frame by drilling required holes and routing mortise cavity as specified in manufacturer instructions for 2-3/4" backset configuration.
  4. Install all mounting hardware and secure the lock case to door mortise per manufacturer torque specifications, ensuring armored front self-aligns with door bevel.

BEST 45H7C3J625VIN – Frequently Asked Questions

1) Do I have to order the BEST 45H handed, or can it be reversed in the field?
Door hand is a required selection (left hand, right hand, left hand reverse, right hand reverse), but the lock body itself is non-handed: the latch rotates 180 degrees to change handing without opening the case, and there is a four-position hub toggle. The auxiliary bolt is non-handed as well. So a mis-ordered hand is recoverable on site.
2) What does the C public entrance function on this BEST mortise lock actually do?
Public entrance is a keyed single-cylinder function, and on this version a visual indicator on the outside shows status: an open padlock icon when unlocked, a closed padlock icon painted red when locked. Staff can see from the corridor whether the opening is secured without trying the lever. That is why it gets specified on lobby, retail, and multi-tenant entries.
3) Does the BEST 45H come with a cylinder or core?
No. It ships with SFIC prep less core, meaning the housing is there for a small format interchangeable core but the core is not included. Order the core separately in your keyway and keying. A cylinder security screw keeps the cylinder from being removed until the core is pulled first.
4) Will the 45H latch into the strike that's already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, both solid stainless. Those are standard throws for a commercial mortise lock, so an existing ANSI mortise strike with the right lip projection will normally catch. The one-piece anti-friction latch has about 50 percent more surface contact with the strike than the older design, and the armored front self-aligns to the door bevel during installation.
5) Is this BEST mortise lock Grade 1, and what do I need to add to hit Grade 1 security?
The 45H Series is rated ANSI A156.13, Series 1000, Grade 1 Operation and Strength, with Grade 2 Security as supplied. To reach Grade 1 Security you need a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. The 47H Series is Grade 1 for operation, strength and security out of the box if you don't want to specify a special core.
6) If the opening needs a storeroom function instead of public entrance, what mortise lock should I use?
For a storeroom opening, the Accentra 8805FL from the 8800 Series is a Grade 1 storeroom mortise lock supplied 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 BEST 45H C is a public entrance function lock with a visual keyed indicator, so it is the wrong function where the outside lever must stay locked at all times.
7) Can I use the BEST 45H public entrance lock on a classroom door, or is there a better mortise lock for that?
For classroom openings, use a classroom function mortise lock. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors in the ML2000 Series, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors. The BEST 45H C is a public entrance function lock, which retracts the latch from the outside lever when unlocked rather than holding a classroom key-outside arrangement.
8) Will a Baldwin 6301 or 6310 mortise lock body drop into the same door prep as the 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 built on a 2-3/4 inch backset, so the cylinder and hub centers do not line up with a 45H mortise pocket. The Baldwin bodies are offered in knob by knob and lever by lever arrangements for doors 1-3/4 inch and over on the 6301 and 1-3/8 inch and over on the 6310.
9) What trim and lever choices do I have to specify when ordering the BEST 45H?
Three decisions besides finish and hand. Trim style: H rose, R rose, or J wrought escutcheon. Lever or knob design: 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, or 4 round knob. Note that the drill-resistant-core route to Grade 1 security applies to escutcheon trim, while sectional (rose) trim uses the high security cylinder instead.
10) Which finish should I pick for a hospital or clinic corridor?
BEST offers two UltraShield antimicrobial finishes on the 45H: 626AM satin chrome and 630AM satin stainless steel. The coating inhibits growth of bacteria and other microbes on the hardware surface, and BEST recommends it for healthcare, elderly care, education, transportation, food service and hospitality. If antimicrobial isn't a requirement, plain 626 and 630 are the same appearance, and the full range runs 605, 606, 611, 612, 613, 618, 619, 622, 625, 626, 629, 630 and 690.
11) I have a mix of storeroom and classroom doors. Can I stay with mortise locks across the whole building?
Yes, and the 45H family is built for exactly that kind of standardization. The C public entrance function covers lobby and tenant entries. For storeroom and classroom openings ZenSupply also carries Grade 1 mortise locks in those functions from other lines, such as the Cal-Royal NM8080 storeroom and NM8070 classroom (both 1-3/4 inch doors), the Corbin Russwin ML2003 classroom, and the Accentra 8805FL storeroom. Keeping the same SFIC keyway across them is what makes a master key system practical.
12) If I want keypad or credential access on the same mortise prep instead of a keyed BEST 45H, what are the options?
Several electronic mortise locks cover that. The Schlage CO-100-MS standalone electronic mortise lock is Grade 1 heavy duty with a keypad reader for 1-3/4 inch doors, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID, and the Dormakaba E-Plex 5086 is a Grade 1 back to back pushbutton and card mortise lock. The BEST 45H C is a non-electronic mechanical lock, so choose it when the opening is managed by keys and a visible locked/unlocked indicator rather than by credentials.
13) What is a lower-cost keyed mortise lock alternative to the BEST 45H if I do not need the indicator or small format interchangeable core?
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 it covers a similar keyed entrance role without indicator hardware. The BEST 45H C is supplied with an SFIC housing less core, so it is the one to keep if the building is already keyed to a small format interchangeable core system.
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 has no cylinder and no locking function at all. The BEST 45H C is a keyed single cylinder mortise lock with a visual keyed indicator. Use the PM010 only where the door never needs to lock; it will not stand in for a keyed public entrance opening.
15) For a behavioral health or ligature-resistant opening, is the BEST 45H appropriate or should I look at something else?
Look at a ligature-resistant trim instead. The TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel and the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset, both passage function for 1-3/4 inch doors. The BEST 45H C uses conventional lever and knob trim in styles such as curved with return, gull wing and round knob, which is not a ligature resistant profile.
16) I need a privacy mortise lock for a restroom, not a public entrance lock. What takes the place of the BEST 45H there?
Use a privacy function mortise lock. 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 thick, matching the 2-3/4 inch backset of the BEST 45H, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. The 45H C is a keyed public entrance lock and is not intended for restroom privacy duty.
17) What mortise lock should I use for a dormitory corridor door instead of the BEST 45H public entrance function?
The Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, which is the usual choice for corridor and dormitory openings. The BEST 45H C is also heavy duty and single cylinder keyed, but its public entrance function and visual keyed indicator suit lobby and shared entry doors rather than dormitory exit arrangements.
18) Is a Sargent 4874 mortise deadbolt an alternative to the BEST 45H mortise lock?
No, they do different jobs. The Sargent 4874 in the 4870 Series is a double cylinder mortise deadbolt with a 2-3/4 inch backset, so it provides a bolt only with no latch or lever trim. The BEST 45H C is a single cylinder keyed mortise lockset with lever or knob trim, a 3/4 inch stainless latchbolt and a 1 inch deadbolt throw in one case, on the same 2-3/4 inch backset.
19) Is the BEST 45H tough enough for a high-traffic public entrance?
It is a heavy duty commercial mortise lock. Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance, the case is held with four corner screws interlocking with the armored front, and the hub runs on a roller bearing. The latch is oil-impregnated stainless with a precision curve for cycle life. Not a residential-duty product.
20) Does the BEST 45H meet accessibility requirements for lever operation?
BEST states the design and operation of the mortise lock meets the intent of ANSI A117.1 section 404.2.6. Pair that with one of the lever designs rather than the 4 round knob if the opening is on an accessible route.
21) Is a strike included with the BEST 45H mortise lock, or do I order it separately?
Strike is specified as part of a strike package rather than assumed with the lock body, so confirm which strike you need for your frame condition when you order. BEST publishes the complete strike package specifications in the 40H Series mortise lock catalog and covers frame fitment in the 45H/47H installation instructions.
