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 the 2-3/4" backset configuration.
  3. Prepare door mortise pocket to accommodate the 5-7/8" H x 7/8" D x 4-1/16" W case dimensions and route for the 8" H x 1-1/4" W faceplate.
  4. Install the lockbody into the mortise pocket and secure with appropriate fasteners per manufacturer torque specifications.
  5. Configure the four-position hub toggle settings and locking toggle positions for the desired entrance function operation.

BEST 45HCABW626 – Frequently Asked Questions

1) Does the BEST 45HCA mortise lock come with a cylinder or core?
No core is included. The 45HCA lock body is prepped for a BEST small format interchangeable core (SFIC) and ships less core, so you supply the 6- or 7-pin SFIC in your facility's keyway and keying. It is a single cylinder keyed function, meaning key access from the outside only. If you are standardizing a building on one key system, this lets you pin the cores yourself and keep the lock bodies keyway-neutral.
2) Do I have to order the BEST 45HCA mortise lock handed, or can I change it in the field?
Handing is a required selection when ordering (RH, LH, RHRB, or LHRB), but the latch itself is reversible in the field. The latchbolt rotates 180 degrees without opening the case, so if the opening turns out opposite to what the drawing said, you correct it at the door instead of returning the lock. That also means a property manager can stock fewer spare bodies across a mixed set of openings.
3) What door prep and thickness does the BEST 45HCA mortise lock body need?
Standard configuration is built for a 1-3/4 inch door, which is the usual commercial thickness. The mortise pocket has to take a case measuring 5-7/8 H x 7/8 D x 4-1/16 W, with the edge routed for an 8 x 1-1/4 x 1/16 inch faceplate, and the cross-bore centers set to a 2-3/4 inch backset. For anything thicker, BEST builds a thick-door configuration up to 5 inches, but the thickness has to be called out on the order.
4) Will the 45HCA latch and deadbolt work with the strike already in my frame?
The latchbolt throws 3/4 inch and the deadbolt throws a full 1 inch, so the frame has to be pocketed deep enough behind the strike for a 1 inch bolt, not just a latch cutout. The faceplate self-adjusts to the door bevel during installation, which helps alignment, but a frame prepped only for a cylindrical latch will not accept this. If your frame lip sits proud, the 7/8 inch lip-to-center strike is an order option.
5) What does the entrance/office function actually do on the BEST 45HCA?
Entrance function on the 45HCA: the key retracts the latch from outside and the inside lever always retracts it for free egress. A four-position hub toggle in the case sets whether each hub is always locked, always unlocked, or locked by key, so you can leave a suite door unlocked through business hours and secure it after. The separate 1 inch deadbolt is thrown by key or inside turn.
6) Is the BEST 45HCA Grade 1, and does it meet Grade 1 security?
The 45H Series meets ANSI A156.13, Series 1000, Grade 1 for Operation and Strength, and Grade 2 for Security as standard. 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 your spec demands Grade 1 security out of the box, the 47H Series carries Grade 1 for Operational, Strength and Security. The design also meets the intent of ANSI A117.1 section 404.2.6.
7) Do I need to order levers or trim separately with the 45HCA?
Yes. The 45HCA is a lock body only. Levers or knobs, roses or escutcheons, the SFIC core, and the strike package are all ordered on top of it. Trim choice also affects the security rating path, since escutcheon trims pair with drill resistant cores and sectional trims with the high security cylinder. Budget the full assembly, not just the case, when you are pricing an opening.
8) Which finish should I pick for a hospital or clinic door?
For healthcare, elderly care, food service and similar high-cleanliness work, BEST offers two UltraShield antimicrobial finishes: 626AM satin chrome and 630AM satin stainless. The coating inhibits bacterial and microbial growth on the hardware surface. Beyond those, the 45HCA comes in 605, 606, 611, 612, 613, 618, 619, 622, 625, 626, 629, 630 and 690. Note 613 oil-rubbed bronze is meant to wear to an antique look, so it is a poor choice where you need every door to match years from now; 690 stays dark brown.
9) Is a mortise lock like the 45HCA worth it over a cylindrical lockset?
On a high-traffic commercial opening, yes, provided the door is prepped for a mortise pocket. A mortise body like the 45HCA puts the latch and a 1 inch deadbolt in one case with an armored front wrapping both for lateral strength, uses a roller bearing hub for cycle life, and carries Grade 1 operation and strength. A cylindrical lock is cheaper to prep but gives you no integral deadbolt. The catch is retrofit: a door bored for a cylindrical lock cannot take this without a new mortise pocket, so on existing wood or hollow metal doors confirm the pocket first.
10) What are the security head screws on the 45HCA order form for?
They are a required yes/no selection when ordering the 45HCA. Choosing yes gets tamper resistant fasteners instead of standard heads, which is what you want on detention-adjacent, school corridor, or public restroom openings where someone can reach the exposed screw heads. On a private office suite it is usually unnecessary.
11) How durable is the case on the BEST 45HCA, and will it corrode in a damp stairwell?
The case, cover and armored front are 0.095 inch cold rolled steel, and the steel is zinc dichromate plated for corrosion protection. Latchbolt and auxiliary bolt are stainless, with the latch oil-impregnated for anti-friction operation; the auxiliary bolt is non-handed. It is classed as heavy duty commercial hardware, which is the level you want on exterior-adjacent and high-cycle interior openings.
