STI KIT-M05603-B Replacement Lens for SA5600 Blue

Overview

The KIT-M05603-B is a replacement lens assembly in blue for the STI SA5600 electric strike system. Use this when the original lens element shows wear, discoloration, or optical damage — it restores visibility and functional aesthetics without replacing the entire strike mechanism. Designed for integrators managing field maintenance on existing SA5600 installations where the strike body remains sound but the lens requires renewal.

Compatibility

Direct replacement for STI SA5600 door strike assemblies. Operates at 9VDC, matching the SA5600 parent system voltage specification. Installation integrates into existing wiring without modification to the strike's electrical infrastructure or mounting footprint.

Installation Notes

Replacement is mechanical — no tools beyond standard hand tools are required. The lens assembly seats into the SA5600 frame and retains the factory alignment and sealing characteristics of the original. Confirm power is disconnected during replacement to prevent accidental activation. No special torque specifications or environmental restrictions apply beyond the operating range of the parent SA5600 system.
