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), backset requirements, and handing as applicable to this mortise lockbody.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces for proper mortise preparation.
  3. Prepare door by cutting mortise pocket to accommodate the 5-7/8" H x 7/8" D x 4-1/16" W case dimensions and route faceplate area as specified.
  4. Install the lockbody into the prepared mortise and secure with appropriate fasteners per manufacturer torque specifications.
  5. Configure the four position hub toggle to determine locking operation for each hub and adjust reversible latch orientation as needed for door handing.
  6. Test lockbody operation to verify proper function of all mechanisms and make final adjustments as needed. Refer to manufacturer documentation for complete installation details and troubleshooting.

BEST 45HCAWD626 – Frequently Asked Questions

1) What does the WD deadlock function on a BEST 45HCA mortise lock actually do?
Deadlock function means there is no knob, lever or latch operation at all. It is a key-thrown deadbolt in a mortise case, double cylinder, so it is keyed from both sides and there is no thumbturn release. The bolt is stainless steel with a 1 inch throw. Use it where you want a mortise-format deadbolt on an opening, not a latching lockset. If people need to get through the door without a key, this is the wrong function.
2) Does the BEST 45HCA lockbody come with cylinders or cores?
No cores are included. The 45HCA ships as a lock body only, prepped for BEST small format interchangeable core and less core, so you supply two SFIC cores to key it (it is a double cylinder function, keyed both sides). Locksmiths pinning to an existing BEST system can drop their own cores straight in. If you need drill resistance, note that the case carries Grade 2 security as built, and Grade 1 security requires a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim.
3) Do I have to specify handing when ordering the BEST 45H mortise lock case?
Handing is a required selection: right hand, left hand, right hand reverse bevel, or left hand reverse bevel. That said, the case is field reversible. The latch rotates 180 degrees without opening the case, so a wrong-hand call is fixable on the job rather than a return. The auxiliary bolt is non-handed.
4) Will a 45HCA mortise lock work in my existing door prep and strike?
The 45HCA uses a 2-3/4 inch backset, which is the standard mortise backset, so it lines up with a mortise pocket cut for a standard commercial mortise lock. The deadbolt throws 1 inch and the latchbolt 3/4 inch, so the strike has to have the depth for a 1 inch bolt. The lock face self-adjusts to the door bevel during installation. If your opening needs it, a 7/8 inch lip to center strike can be added to the order.
5) Is the BEST 45HCA mortise lock ANSI Grade 1?
The 45H series is rated to ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, and Grade 2 for Security. The design also meets the intent of ANSI A117.1 section 404.2.6. If your spec calls for Grade 1 across the board including security, BEST's 47H series is the one rated Grade 1 for Operational, Strength and Security, or you add a drill resistant core to the 45H with escutcheon trim.
6) Which finish should I order for a hospital or clinic mortise lock?
Two antimicrobial options are offered on the 45HCA: 626AM, satin chrome with UltraShield coating, and 630AM, satin stainless with UltraShield. The coating inhibits growth of bacteria and other microbes on the hardware surface, and BEST calls it out for healthcare, elderly care, education, transportation, food service and hospitality. Everything else in the range is a standard finish, so if cleanliness is the driver, the AM suffix is the choice.
7) Is this a complete mortise lockset or just the lock case?
Lock body only. The 45HCA is the mortise case that goes in the door pocket, with the faceplate and the deadbolt mechanism. Because the function is deadlock, there is no lever or knob trim in the package, and no cores, so a full opening needs the cores and the appropriate cylinder trim or escutcheon plus a strike. Contractors bidding this should price the case, the cores and the trim separately.
8) What finishes does the BEST 45HCA mortise lockbody come in?
Fifteen in all: 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 antimicrobial. Worth knowing on a building where you are matching openings: 613 is meant to wear to an antique appearance over time, and 690 stays a dark brown. The rest are clear coated or plated and hold their look.
9) Can I get tamper resistant screws on a BEST mortise lock case?
Yes, security head screws are an ordering option on the 45HCA, selected yes or no when you place the order. On a case that already uses four cover screws at each corner with an interlocking armored front, security heads are the sensible add on high-abuse openings like schools, transit and multi-tenant corridors.
10) How durable is the BEST 45HCA case for a high traffic commercial door?
The case, cover and armored front are 0.095 inch cold rolled steel, zinc dichromate plated against corrosion, with a roller bearing hub mechanism for wear resistance. The latch is solid one-piece stainless, oil impregnated, and BEST claims 50 percent more surface contact with the strike than a conventional latch. It is classed heavy duty and commercial, not residential, and it is a purely mechanical lock with no electronics in it.
