BEST 45H0N3H626 – Frequently Asked Questions

1) What does passage function mean on this 45H series mortise lock?
Passage function means the lock is non-keyed and allows free movement through the door from both sides. The lever operates the latch mechanism without any locking capability. Ideal for interior doors where privacy or security is not required.
2) What door thickness does this heavy duty mortise lock accommodate?
Standard mortise locks typically fit 1-3/4" doors. Check the manufacturer template for exact specifications and backset requirements. Verify your door thickness and mortise pocket dimensions before installation.
3) How do I determine proper handing for this mortise lock?
Stand on the side where the door swings away from you. If hinges are on your right, order right hand. If hinges are on your left, order left hand. Most mortise locks are field reversible for both handing and backset.
4) What finishes are available for the 45H series rose trim?
Common finishes include satin chrome, polished brass, oil rubbed bronze, and satin stainless steel. Verify available finishes with the specific model number as options may vary by manufacturer and trim style.
5) What grade rating does this heavy duty mortise lock meet?
Heavy duty mortise locks typically meet ANSI Grade 1 or Grade 2 standards for commercial use. Grade 1 offers highest durability for high-traffic applications. Confirm the specific grade rating with the manufacturer specifications.
6) Does this lock meet ADA accessibility requirements?
Mortise locks with lever handles typically meet ADA requirements when properly installed. Lever must operate with 5 pounds of force or less and be mounted between 34" and 48" from floor. Verify compliance with local accessibility codes.
7) What components are included with the complete lock set?
Complete sets typically include mortise lock body, rose trim plates, levers, strike plate, and mounting hardware. Installation template and instructions should be included. Verify all components are present before beginning installation.
8) What tools are needed for mortise lock installation?
Basic installation requires drill, hole saw, chisel set, screwdrivers, and measuring tools. A mortise jig can ensure precise pocket cutting. Follow manufacturer template exactly for proper alignment and operation.
9) How do I adjust the latch if the door doesn't close properly?
Check strike plate alignment first. Latch may need slight adjustment up, down, or in/out. Some mortise locks have adjustable latch bolts. Ensure door is properly hung and strike plate is positioned correctly.
10) Are there keyed versions available in the 45H series?
Yes, 45H series typically offers multiple functions including entrance, privacy, classroom, and storeroom. Browse our door hardware section for keyed options and different function types.
11) What is the standard backset measurement for this lock?

12) Can this mortise lock be used on fire rated doors?
Fire rated applications require locks with proper fire rating certification. Check for UL fire rating marking on the lock body. Consult fire door manufacturer requirements and local fire codes for approved hardware.
