BEST Lockset - 40H Series
Mortise Locks
45H Universal Models with Latchbolt or Deadbolt, Less Core
If you want to keep your options open, this method of ordering the 40H is for you. BEST has developed three “universal” functions that can be configured to a variety of common functions, all without opening the lock case. When any of the universal functions are ordered as a complete lock, all the necessary parts (including trim) are provided to configure any of the functions in that group.
In addition to the ability to quickly change the lock handing, the universal case design of the 40H provides the ability to reconfigure a lock into many different functions easily and quickly, often by rearranging existing parts without disassembling the lock case. The efficiency of the design enables over 12 of the most commonly used lock functions to be included in just 3 case configurations.
The 40H provides the ability to postpone decisions on how the lock will be configured all the way up to the point of installation, making it one of the most flexible and user-friendly mortise locks available. This translates into value for anyone involved in the process, whether they’re an architect, specification writer, distributor, or end-user.

Features of the 45H Series Mortise Locks:
- Solid one-piece stainless steel anti-friction latch provides 50% more surface contact with strike for superior strength and security. Reversible latch rotates 180 degrees for easy handing change without opening case. Precision-engineered curve provides enhanced cycle life with reduced wear to the strike.
- Non-handed cylinder retainer and stainless steel auxiliary bolt for ease of changing hand
- Armored front completely surrounds latch and deadbolt providing increased lateral strength. Staked assembly design allows the armored front to self-align with the door bevel during installation.
- Enhanced case integrity achieved through four case cover screws (one at each corner), plus interlocking armored front and cover design at the latch
- Roller bearing hub mechanism provides smooth, wear resistant operation
- Locking toggle includes clear indication of “locked” and “unlocked” states
- 40H case, cover, and armored front manufactured from 0.095” cold rolled steel for strength and durability
- Fusible link
- Four position hub toggle design determines whether each hub is always locked, always unlocked, or locked by key for easy handing change without opening case
- Lever return spring mechanism located in trim for enhanced protection against lever droop, providing a firm, positive return of the lever to the horizontal position
- Self-aligning trim mechanism for fast, easy, and accurate installation
- Curved lip strike and strike box assembly provides an aesthetic, non-handed solution to complement field reversible case
- Solid machined cylinder rings with tension spring provide resistance to wrenching of cylinder. Cylinder security screw prevents removal of cylinder without first removing interchangeable core.
