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 alignment.
  3. Prepare door mortise pocket and drill required holes per manufacturer specifications, ensuring proper clearance for case dimensions and armored front assembly.
  4. Install mortise case into door pocket and secure with provided screws, allowing armored front to self-align with door bevel during installation.
  5. Configure four-position hub toggle to determine locked/unlocked operation for each hub and install trim components with self-aligning mechanism for accurate positioning.
  6. Test lock operation including latch and deadbolt function, visual indicator operation, and lever return spring mechanism to verify proper alignment and smooth operation throughout full range of motion.

BEST 45H7T3J626VIN – Frequently Asked Questions

1) What does dormitory function mean on a mortise lock, and is it the right function for a student housing door?
Dormitory function on the 45H means the outside lever is locked or unlocked by key, and the deadbolt is thrown from the inside. It suits student housing, hotel guest rooms, patient rooms, and multi-tenant residential where the occupant needs to secure the room from inside while staff retain key access. If you want a door that stays locked outside at all times and only the key retracts the latch, that is storeroom function, not dormitory.
2) Do I have to specify handing when ordering the BEST 45H mortise lock?
Yes. Hand is a required selection - left hand, right hand, left hand reverse, or right hand reverse. The latchbolt itself is reversible without opening the case, but the trim and indicator orientation follow the hand you order, so pick it off the actual door swing rather than assuming.
3) Does the BEST 45H come with a core, or do I need to order cylinders separately?
It ships as an SFIC housing less core. The small format interchangeable core has to be ordered separately and keyed to your system, which is the normal arrangement for a facility running a BEST SFIC master key system - you drop your own cores in and control the keying. Single cylinder, keyed outside.
4) Is the BEST 45H Grade 1, and what do I need to hit Grade 1 security?
The 45H meets ANSI A156.13 Series 1000, Grade 1 for Operation and Strength, but Grade 2 for Security as standard. To reach Grade 1 Security you need 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 says Grade 1 security across the board without those cores, look at the 47H series instead, which carries Grade 1 for operation, strength and security.
5) What is the closest dormitory function mortise lock to the BEST 45H if I need a different brand?
The Sargent 7925 is the nearest peer. It is a Grade 1 heavy duty mortise lock with a dormitory exit function, rose trim, and a single cylinder deadbolt, from the 7900 Series. The BEST 45H is also a heavy duty dormitory function mortise lock with a 2-3/4 inch backset and a single cylinder keyed function, and it adds a visual keyed indicator showing an open padlock icon for unlocked and a closed red padlock icon for locked. The 45H is ordered with SFIC prep less core, so it takes a small format interchangeable core; the Sargent 7925 is a conventional 7900 Series lock. Choose based on whether your keying program is SFIC and whether you need the indicator.
6) Is the Accentra 8805FL a drop-in replacement for a BEST 45H dormitory lock?
Not function for function. The Accentra 8805FL is a Grade 1 storeroom function mortise lock from the 8800 Series with an Arcadia lever, meaning the outside lever stays locked at all times and a key retracts the latch. The BEST 45H covered here is a dormitory function lock with a visual keyed indicator, where the outside lever can be left locked or unlocked and the indicator reports which state it is in. If you want an always-secure entry with no occupant control, the 8805FL fits; if occupants need to set and read the lock status, stay with the 45H dormitory function.
7) Will a Baldwin 6301 mortise lock body fit a door prepped for the BEST 45H?
No. The Baldwin 6301 entry/apartment mortise lock body is a 2-1/2 inch backset lock, offered knob by knob or as the 6301LS lever by lever, for doors 1-3/4 inches and over. The BEST 45H uses a 2-3/4 inch backset, so the cylinder and hub centerlines sit a quarter inch further from the door edge and the trim holes will not line up with a 45H preparation. Match backset to the existing pocket before ordering either one.
8) What is the point of the visual indicator on the BEST 45H, and what does it actually show?
The indicator shows a padlock icon: open for unlocked, closed and painted red for locked. On a dorm or patient room door it lets the occupant confirm status without testing the lever, and lets staff read the door from the corridor. That is the whole reason to pay for the indicator version over a plain 45H dormitory lock.
9) Which antimicrobial finishes does BEST offer on the 45H for a hospital or care facility?
Two: 626AM, satin chrome with UltraShield antimicrobial coating, and 630AM, satin stainless with the same coating. The coating inhibits bacterial growth on the hardware surface. BEST calls these out for hospital and elderly care, but also education, transportation, food service and hospitality - anywhere cleanliness is being audited. Everything else runs through the standard range, 605 bright brass through 690 statuary dark bronze.
10) What trim and lever choices do I have to pick on the BEST 45H, and does the trim affect anything besides looks?
Trim comes as H rose, R rose, or J wrought escutcheon, with seven lever and knob styles: 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, and 4 round knob. Trim style is not purely cosmetic here - the Grade 1 security upgrade path differs, with drill resistant cores called for on escutcheon trims and the high security cylinder on sectional trims.
11) If I do not need the indicator, what else could I use for a dormitory or corridor mortise lock?
The Sargent 7925 is the closest equivalent without a visual indicator - a Grade 1 heavy duty corridor/dormitory function mortise lock with rose trim and a single cylinder deadbolt. If the requirement is really classroom security with an indicator, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset for 1-3/4 inch doors with an ANSI strike and steel escutcheon. Neither is a BEST SFIC housing, so if you are standardized on BEST cores across the building, staying with the 45H keeps your keying intact.
12) Is the BEST 45H an electronic or access control lock?
No, it is a purely mechanical mortise lock - key and lever, no wiring, no credentials. If the project calls for card or keypad access in a mortise pocket, look at the Schlage CO-100 standalone electronic mortise lock, the TownSteel FME-2000 with RFID, or the Command Access ML190 motorized mortise lock running on 24VDC. Those change the door prep and the power requirement, so they are a different conversation than dropping in a 45H.
13) What is a simpler mortise lock for the interior doors of the same building, where I do not need keying or an indicator?
For non-keyed interior openings, the Hager 3810S is a Grade 1 passage mortise lock with a 2-3/4 inch backset and rose trim for doors 1-3/4 to 2-1/2 inches thick, and the 3810E is the same passage lock with escutcheon trim. For bath and bedroom doors, 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. All three share the 2-3/4 inch backset used on the BEST 45H, so the mortise pocket and backset dimension carry across the building while only the keyed dormitory openings take the 45H.
14) We want credentialed access on dorm doors instead of keys. What replaces the BEST 45H?
The BEST 45H is a mechanical, non-electronic mortise lock, so an access control retrofit means a different lockset. The Dormakaba E-Plex E5086 is a Grade 1 back to back pushbutton and card mortise lock with entry/egress function. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors. All change the cylinder and credential plan, so the SFIC core program the 45H is prepped for will no longer apply at those openings.
15) What mortise lock should I use for office and storeroom doors if I want to keep an interchangeable core program?
The Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option, and the NM8050 is the matching Grade 1 office/entrance lockset with auxiliary deadlatch for 1-3/4 inch doors. The BEST 45H ships with SFIC prep less core, so cores can be swapped without pulling the lock. Deciding between them usually comes down to whether the whole facility is already keyed to one small format core system and whether you need the visual indicator the 45H carries.
16) For a patient room or behavioral health door, is the BEST 45H the right mortise lock?
It depends on whether ligature resistance is required. The BEST 45H is offered in 626AM satin chrome and 630AM satin stainless with UltraShield antimicrobial coating, which suits healthcare cleanliness requirements, and it is a keyed dormitory function lock. Where the opening needs anti-ligature trim, 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, the MRX-A-01 is the same passage lockset with arch trim, and the Marks USA 5PDN is a Grade 1 ligature resistant hospital passage push/pull paddleset that is ADA compliant in satin stainless. Those three are passage function, so they do not key.
17) I only need to add a deadbolt to an existing door, not a full dormitory lockset. What instead of the BEST 45H?
The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, which matches the backset dimension used by the BEST 45H. The Kaba Ilco 185 Series mortise lock is also a deadbolt function unit, supplied with no handing in a single pack. The 45H is a full dormitory function lockset with latch and lever or knob trim, so a standalone deadbolt is the simpler choice when the door already has a working latch.
18) Does the door need to be handed when I order the BEST 45H, and how does that compare to other mortise locks?
Yes, the BEST 45H is ordered by hand, with left hand, right hand, left hand reverse, and right hand reverse choices, although its stainless steel latchbolt is reversible without opening the case and the auxiliary bolt is non-handed. For comparison, the Kaba Ilco 185 Series mortise lock is supplied with no handing, the Falcon MA101 Grade 1 heavy duty mortise passage lock is field reversible, and the Baldwin 6310190RRLS is a fixed right hand reverse lever by lever lock with a 2-1/2 inch backset. Confirm the hand at the opening before releasing any of them.
19) How durable is the BEST 45H case for a high traffic dorm corridor?
The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion. The armored front wraps both the latch and the deadbolt for lateral strength and self-aligns to the door bevel on install. Inside, a roller bearing hub runs the levers, and the one-piece stainless latch is oil impregnated for anti-friction operation with roughly 50 percent more contact surface at the strike. That is the construction that carries the Grade 1 operation and strength rating.
20) Does the BEST 45H meet accessibility requirements for lever operation?
BEST states the design and operation of its mortise lock meets the intent of ANSI A117.1 section 404.2.6. Pick one of the lever options rather than the 4 round knob if accessible operation is the requirement, since a knob needs tight grasping and twisting.
21) What do I set during install to control which side locks on the BEST 45H?
There is a four-position hub toggle inside the case that sets locked/unlocked behavior for each hub. You set it after the case is in the pocket and before the trim goes on. After that, cycle the latch, the deadbolt, the indicator, and the lever return spring through full travel before you close up - a misaligned pocket usually shows up as a lazy lever return first.
22) What classroom function mortise lock pairs with a BEST 45H dormitory lock on the same project?
The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset from the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 heavy duty classroom mortise lockset with auxiliary deadlatch, also for 1-3/4 inch doors. The BEST 45H is the dormitory function lock with a 2-3/4 inch backset. The 45H family is also produced in classroom function, which is the simplest way to keep one keyway and one trim appearance across both door types on a single job.
