Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness (standard 1-3/4" or thick door configuration up to 5"), 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 at 2-3/4".
  3. Prepare door mortise pocket to accommodate case dimensions of 5-7/8" H x 7/8" D x 4-1/16" W and route faceplate opening for 8" H x 1-1/4" W dimensions.
  4. Install lock body in mortise pocket ensuring armored front self-aligns with door bevel during installation and secure with four corner case cover screws.
  5. Configure four position hub toggle design for desired operation (always locked, always unlocked, or locked by key) and verify latch reversibility if handing change is required.
  6. Test lock operation to verify proper function of privacy mechanism, latch throw (3/4"), deadbolt throw (1"), and visual lock indicators. Refer to manufacturer documentation for complete installation details and troubleshooting.

BEST 45HCALB626 – Frequently Asked Questions

1) Will the BEST 45HCA privacy mortise lock body fit a 1-3/4 inch door?
Yes. The standard 45HCA lock body configuration is built for 1-3/4 inch doors, which is the common commercial thickness. For anything thicker, BEST builds a thick door configuration good up to 5 inches, but you have to specify the actual door thickness when you order. The mortise pocket needs to take a case of 5-7/8 H x 7/8 D x 4-1/16 W inches, with an 8 x 1-1/4 inch faceplate cutout, and the backset is 2-3/4 inches.
2) What do I have to specify when ordering a BEST 45HCA mortise lock body?
Four things get picked at order time on the 45HCA. Handing is required: right hand, left hand, right hand reverse bevel, or left hand reverse bevel. Finish is required, from fifteen choices. Then two yes/no adds: security head screws, and a 7/8 inch lip-to-center strike instead of the standard one. If the door is thicker than 1-3/4 inches you also state the thickness so the thick door configuration is built.
3) Do I need a cylinder or a core for a BEST 45HCA privacy lock?
No key cylinder is used to operate it. The 45HCA is a privacy function lock, non-keyed, so it locks from the inside with the thumbturn or button trim rather than by key. The body does carry the BEST SFIC prep and ships less core, so if your spec calls for an emergency release core in the outside trim you can still populate that prep with a BEST small format interchangeable core.
4) Is the BEST 45HCA lock body handed, and can I change the handing in the field?
It ships handed, but you are not stuck with it. The latch reverses by rotating 180 degrees without opening the case, and the auxiliary bolt is stainless and non-handed. So a job where the door swing turns out opposite to the takeoff does not need a new lock body, just a field reversal. Still order the handing you expect, since the trim and strike side of the job follow it.
5) Will the BEST 45HCA latch into the strike that is already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, both solid stainless, on a 2-3/4 inch backset. If your existing frame is prepped for an ANSI mortise strike at that backset, the geometry lines up. Where the frame or the door has a deep rabbet, order the 7/8 inch lip-to-center strike option instead of the standard lip so the latch is not overhung.
6) Does the BEST 45HCA come with levers, trim, or a faceplate?
It is the lock body only. Levers or knobs, roses or escutcheons, and the thumbturn side of the privacy trim are ordered separately in the matching 45H trim, and so is the strike package. The faceplate spec for the mortise pocket is 8 x 1-1/4 x 1/16 inches stainless, brass, or bronze, and the lock face self adjusts to the door bevel as you install it.
7) Does the BEST 45H mortise lock meet ANSI Grade 1 security, or only Grade 1 strength?
The 45H Series is rated ANSI A156.13, Series 1000, Grade 1 for operation and strength, with a Grade 2 security rating. To reach Grade 1 security you either use a drill resistant core (1CD, 1CDP, 1CDF, or 1CDX) with escutcheon trims, or a 1EK7K4 high security cylinder with sectional trims. If your spec calls for Grade 1 across all three categories out of the box, the 47H Series carries Grade 1 operational, strength, and security.
8) Should I use a mortise privacy lock or a cylindrical one for restrooms and patient rooms?
A mortise privacy body like the 45HCA puts a 1 inch deadbolt plus a 3/4 inch latch inside a steel case pocketed into the door, and carries an ANSI A156.13 Series 1000 Grade 1 operation and strength rating. That is the choice for high traffic commercial restrooms, patient rooms, and dorm baths where a cylindrical bored lock gets beaten up. It also means the door has to be mortised, not just bored, so on an existing bored opening you are looking at a door change or a mortised replacement door.
9) What finish should I order to match the rest of my building's hardware?
Fifteen finishes are built: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed satin bronze, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, 690 statuary dark bronze, plus 626AM and 630AM. Match the BHMA number on the existing hardware, not the name. Note that 613 is meant to wear to an antique look over time, so it will not stay uniform against newer doors.
10) What are the 626AM and 630AM antimicrobial options on BEST mortise locks?
Those are 626 satin chrome and 630 satin stainless with the BEST UltraShield antimicrobial coating, which inhibits growth of bacteria and other microbes on the hardware surface. BEST recommends them where cleanliness drives the spec: hospitals and healthcare, elderly care, education, transportation, food service, and hospitality. Everything else about the lock body is unchanged, so you can run AM finishes on patient room and restroom doors and standard 626 or 630 elsewhere in the same building.
11) Does the BEST 45HCA mortise lock meet accessibility requirements for lever operation?
The design and operation of the BEST mortise lock meets the intent of ANSI A117.1 section 404.2.6, which is the door hardware operation provision. Pair it with lever trim rather than knob trim to keep the opening compliant, and note the trim carries a lever return spring to guard against lever droop over time.
12) Is the BEST 45HCA an electrified lock body?
No, it is a purely mechanical privacy mortise body with no electrical option. There are no wires to pull, no power transfer hinge, and no fail safe or fail secure behavior to specify. If the opening needs access control or remote release, this is the wrong body and you want an electrified mortise lock instead.
13) How durable is the BEST 45HCA lock case for high traffic openings?
Case, cover, and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion resistance. The armored front wraps both latch and deadbolt for lateral strength, four case cover screws land at each corner, and the armored front interlocks with the cover at the latch. The hub runs on roller bearings, and the stainless latch is oil impregnated and shaped for more strike contact. That is the construction behind the Grade 1 operation and strength rating.
14) Can you tell from outside the door whether a BEST privacy mortise lock is locked?
The locking toggle gives clear indication of locked and unlocked states, and an optional visual indicator showing padlock icons is available. On restroom and patient room doors that is what staff and maintenance look at before knocking, so specify the indicator option if occupancy needs to read at a glance.
