40H Series – Features
1. Solid one-piece stainless steel anti-friction latch provides 50% more surfacecontact 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.

5. Roller bearing hub mechanism provides smooth, wear resistant operation.
6. Locking toggle includes clear indication of “locked” and “unlocked” states. 7. 40H case, cover, and armored front manufactured from 0.095” cold rolled steel for strength and durability.

10. 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.
11. Self-aligning trim mechanism for fast, easy, and accurate installation.
12. Curved lip strike and strike box assembly provides an aesthetic, non-handed solution to complement field reversible case.
13. Solid machined cylinder rings with wavy washer provides resistance to wrenching of cylinder. Cylinder security screw prevents removal of cylinder without first removing interchangeable core.
