Frequently Asked Questions
What is a deadlatch?
A deadlatch is a mechanical locking device that uses a spring-loaded latch which automatically locks when the door closes. At National Lock Supply, we offer Grade 1 deadlatches designed for aluminum storefront doors and commercial entrances.
How does a deadlatch differ from a deadbolt?
Unlike a deadbolt, which requires manual locking, a deadlatch relocks automatically after the door closes. This makes it more convenient for high-traffic entry doors.
What door prep is required?
Deadlatches are designed for narrow stile aluminum storefront doors, typically accepting mortise or rim cylinders for key control.
What functions are available?
Common functions include nightlatch, storeroom, and entry. These determine whether the outside handle is free, locked, or requires a key.
What grades are offered?
Commercial deadlatches are usually ANSI/BHMA Grade 1, tested for heavy-duty use.
Are deadlatches ADA compliant?
Yes, when paired with lever or paddle trims that allow operation without tight grasping.
Where are deadlatches commonly used?
They are standard in storefront doors, retail entrances, and service doors where automatic relocking is required.
What finishes are available?
Deadlatches are offered in Satin Aluminum, Dark Bronze, Satin Chrome, and Black to match storefront hardware.
Can deadlatches be keyed alike with other locks?
Yes. They accept mortise cylinders, rim cylinders, or interchangeable cores, allowing integration into master key systems.
