40H Series
Heavy Duty Mortise Locks

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.
2. Non-handed cylinder retainer.
3. Armored front completely surrounds latch and deadbolt providing increased lateral strength. Staked assembly design allows the armored front to selfalign with the door bevel during installation.
4. Enhanced case integrity achieved through four case cover screws (one at each corner), plus interlocking armored front and cover design at the latch.
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.
8. Fusible link.
9. 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.
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.

BEST 45H7A3J618 – Frequently Asked Questions

1) What is the 45H Series A Office Function mortise lock designed for?
The 45H Series A Office Function lock provides single-keyed access with heavy-duty mortise construction. It's designed for commercial office doors where exterior key control and interior privacy override are required.
2) What door thickness and backset does this mortise lock accommodate?
Standard mortise locks typically fit 1-3/4" doors with 2-3/4" backset. Verify your door preparation matches the manufacturer's template before installation. Check door weight capacity requirements for proper operation.
3) How do I determine the correct handing for this mortise lock?
Stand on the side where the door swings away from you. If hinges are on the right, it's right-handed. If hinges are on the left, it's left-handed. Order the corresponding hand configuration.
4) What escutcheon trim options are available with this lock?
The lock includes office function escutcheon trim as specified. Trim styles may include lever handles or knobs depending on the configuration. Verify trim compatibility with your door preparation.
5) What grade rating does this heavy-duty mortise lock meet?
Heavy-duty mortise locks typically meet Grade 1 or Grade 2 ANSI/BHMA standards. Check the specific grade rating on the product specifications for cycle count and security requirements.
6) Does this lock meet fire door and accessibility code requirements?
Verify fire rating compatibility if installing on fire-rated doors. Check that operating force and hardware height meet ADA accessibility requirements. Consult local building codes for specific applications.
7) What components are included with the complete lock set?
Complete sets typically include the mortise lock body, escutcheon trim, strike plate, and mounting hardware. Keys are usually included with keyed functions. Verify all components before installation.
8) What door preparation is required for installation?
Mortise locks require a rectangular pocket mortised into the door edge and holes drilled for the cylinder and trim. Use the manufacturer's template for precise measurements and hole locations.
9) How do I maintain and adjust this mortise lock?
Lubricate moving parts with graphite or appropriate lock lubricant. Adjust latch and deadbolt projection as needed. Check strike alignment periodically. Avoid over-tightening trim screws which can bind operation.
10) What other 45H Series functions are available?
The 45H Series typically offers multiple functions including classroom, storeroom, entrance, and privacy configurations. Browse our door locks section for related functions and compatible hardware.
11) Can this lock be installed in exterior door applications?
Office function locks can be used on exterior doors where key access from outside and privacy override from inside are needed. Ensure proper weather sealing and verify finish durability for exterior exposure.
12) What should I check if the lock operates stiffly or binds?
Check door alignment and strike plate positioning. Verify the mortise pocket isn't too tight. Lubricate the lock mechanism. Ensure trim isn't over-tightened. Door sagging can cause binding issues.
