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 dimensions, and handing requirements.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces for proper mortise preparation.
  3. Prepare door mortise cavity according to case dimensions: 5-7/8" H x 7/8" D x 4-1/16" W, ensuring proper clearance for armored front installation.
  4. Install lock body in mortise cavity and secure with appropriate fasteners, allowing armored front to self-align with door bevel during installation.
  5. Configure four position hub toggle settings to determine locked/unlocked operation for each hub based on application requirements and desired handing.
  6. Test latch and deadbolt operation to verify proper function, smooth operation of roller bearing hub mechanism, and proper lever return to horizontal position. Refer to manufacturer documentation for complete installation details and troubleshooting.

BEST 45HCABA626 – Frequently Asked Questions

1) Does the BEST 45HCA mortise lock come with a cylinder or core?
No core is included. The 45HCA entrance lock body is prepped for a BEST small format interchangeable core and ships less core, so you order the SFIC core separately and key it into your existing system. It is a single cylinder keyed function, meaning key operation on one side only.
2) Is the BEST 45HCA lock body handed, or can I change the hand in the field?
Handing is field reversible. The latch rotates 180 degrees without opening the case, and the four position hub toggle lets you set which hub is locked or unlocked. You still pick a hand when ordering (RH, LH, RHRB or LHRB) so the lock arrives configured for the opening, but a wrong call on the drawing is fixable at the door rather than a return.
3) Will the BEST 45HCA mortise lock fit a door thicker than 1-3/4 inches?
Standard configuration is built for 1-3/4 inch doors, which covers most commercial openings. For anything thicker, BEST builds a thick door configuration up to 5 inches, and you have to specify the actual door thickness when you place the order. It is not something you adapt after the fact.
4) Will the 45HCA latch into a strike already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws a full 1 inch, both solid stainless steel, on a 2-3/4 inch backset. If your existing frame is prepped for a standard ANSI mortise strike at that backset, the geometry lines up. A 7/8 inch lip to center strike is available as an order option when the frame or stop condition calls for a longer lip.
5) Does the BEST 45HCA include levers, roses or escutcheon trim?
No. This is the lock body only, field reversible, entrance function. Levers or knobs, roses or escutcheons, and the SFIC core are all ordered separately. Worth knowing on install: the lever return spring sits in the trim, not the case, which is what keeps levers from drooping over time.
6) Is the BEST 45HCA Grade 1, and what does it take to get Grade 1 security?
The 45H Series is rated to ANSI A156.13, Series 1000, Grade 1 Operation and Strength, with Grade 2 Security as supplied. To reach Grade 1 Security you have to add a drill resistant core (1CD, 1CDP, 1CDF or 1CDX) with escutcheon trim, or a 1EK7K4 high security cylinder with sectional trim. If the spec on your drawing says Grade 1 security outright, the 47H Series is the one that meets operational, strength and security at Grade 1 without that condition.
7) What does entrance function mean on a BEST 45H mortise lock?
Entrance/office function: the outside lever is locked or unlocked by key, and the inside lever always retracts the latch for free egress. It also carries a 1 inch throw deadbolt for when the space is secured. That combination is what offices, suite doors and tenant entries typically get specified with, rather than a storeroom function where the outside lever stays locked at all times.
8) Which finish should I order for a hospital or school door?
BEST offers two antimicrobial options on the 45HCA: 626AM satin chrome and 630AM satin stainless, both with the UltraShield coating that inhibits bacterial growth on the hardware surface. Those are the ones specified for healthcare, elderly care, education, food service and hospitality. The other thirteen finishes run from 605 bright brass through 630 satin stainless and 690 dark bronze.
9) What do I have to specify when ordering a BEST 45HCA lock body?
Four things beyond finish: handing (RH, LH, RHRB or LHRB), whether you want security head screws, whether you need the 7/8 inch lip to center strike, and the door thickness if it is anything other than the standard 1-3/4 inches. Finish is chosen from fifteen options. The SFIC core and the trim are separate line items.
10) Is the BEST 45HCA an electrified lock?
No, it is purely mechanical. There is no solenoid, no monitoring and no wiring in the 45HCA entrance body, so it needs no power transfer hinge or raceway in the door. If the opening has to fail safe or fail secure on an access control system, this is not the body for it.
11) Will a BEST 45HCA hold up on a high traffic commercial entrance?
It is built for it. Case, cover and armored front are 0.095 inch cold rolled steel with zinc dichromate plating for corrosion protection, four case screws at the corners, and an interlocking armored front and cover at the latch. The hub runs on roller bearings, and the one-piece stainless anti-friction latch gives 50 percent more contact surface with the strike. Rated heavy duty and intended for commercial use, not residential.
12) Does the BEST 45HCA 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, the provision covering door hardware operation. Note that the actual operable part is the trim, which is ordered separately, so the lever style you pair with the body is part of meeting that on the finished opening.
13) Do the 613 and 690 finishes on BEST mortise locks stay looking the same?
Neither is a static finish. 613 oxidized satin bronze is oil rubbed and is meant to wear over time into an antique appearance, so doors in different traffic will age differently. 690 dark bronze holds a dark brown appearance as it ages. If you are matching a fleet of existing openings and want them to stay uniform, a plated finish like 626 satin chrome or 630 satin stainless is the steadier choice.
