BEST 45H7AB3M626 – Frequently Asked Questions

1) What is the function of this AB Office deadbolt mortise lock?
This is a deadbolt function mortise lock. The deadbolt extends when the thumbturn is rotated from inside or when locked with key from outside. No lever handle operation affects the deadbolt. Ideal for office perimeter doors requiring secure locking.
2) What door thickness does this 45H series lock accommodate?
Standard mortise locks typically fit 1-3/4" thick doors. Verify your specific door thickness and weight capacity with the manufacturer template. Heavy duty construction suggests it can handle substantial door weights.
3) How do I determine the correct handing for installation?
Stand on the push side of the door. If hinges are on your right, it's right hand. If hinges are on your left, it's left hand. Most mortise locks are field reversible, but verify handing requirements during ordering.
4) What finishes are available for this escutcheon trim?
Commercial mortise locks typically offer finishes like satin chrome, bright brass, oil rubbed bronze, and satin stainless steel. Check product specifications for exact finish options and matching strike plates.

Heavy duty mortise locks are typically Grade 1 or Grade 2 ANSI/BHMA rated. Grade 1 offers highest security and durability for high-traffic commercial applications. Verify specific grade rating for code compliance.
6) Does this lock meet commercial building code requirements?
Mortise locks generally comply with commercial codes when properly specified. Verify fire rating requirements, ADA compliance, and local code specifications with your authority having jurisdiction before installation.
7) What parts are included with this single keyed mortise lock?
Typically includes lock body, escutcheon trim, thumbturn, cylinder, strike plate, and mounting hardware. Single keyed means one cylinder operates from outside. Verify complete parts list and any additional accessories needed.
8) What mortise pocket dimensions are required for installation?
Standard mortise locks require specific pocket dimensions for the lock body. Use the manufacturer's template for exact measurements. Typical pocket depth is around 1" but verify dimensions before cutting door.
9) How do I maintain this mortise lock for optimal performance?
Lubricate moving parts periodically with graphite or appropriate lock lubricant. Check screws for tightness. Clean escutcheon with appropriate cleaner for the finish. Avoid petroleum-based lubricants that attract dirt.
10) Are there other functions available in the 45H series?
Commercial mortise lock series typically offer multiple functions like entrance, privacy, passage, and classroom functions. Check our door locks section for related AB Office models and function variations.
11) Can this lock handle high-traffic commercial applications?
Heavy duty construction indicates suitability for commercial use. Mortise locks generally offer superior durability compared to cylindrical locks. Verify cycle rating and grade specification for your specific traffic requirements.
