Adams Rite 4900-26-101-628 Heavy Duty Dead Latch

Product Description

The ADAMS RITE 4900-26-101-628 is a heavy duty dead latch designed for commercial and institutional door applications. A dead latch uses a spring-loaded plunger that automatically deadlocks the bolt when the door closes, preventing the latch from being pushed back without proper actuation. This mechanism provides a higher level of forced-entry resistance compared to a standard spring latch. It is typically installed by locksmiths, commercial door hardware technicians, or general contractors working on commercial entryways, stairwell doors, and access-controlled openings.

This dead latch is suited for commercial door assemblies where reliable, automatic locking action is required without manual deadbolt operation. Typical installations include office buildings, institutional facilities, and multi-unit residential entry doors. The heavy duty construction makes it appropriate for high-traffic openings that see frequent cycling throughout the day. Installers should verify door prep dimensions and backset requirements before ordering to confirm proper fitment.

Installation Notes

Installation of a dead latch is typically performed by a licensed locksmith or qualified door hardware technician. Before beginning, ensure the door is secured open and any existing electric strike or access control power is disconnected. Verify that the door edge prep, backset dimension, and strike plate cutout match the latch specifications before fastening. Consult local building codes and ADA requirements where applicable for commercial door hardware installations.
