STI STI-4130EM Break Glass Stopper Large with Spacer Emergency

Overview

The STI-4130EM is a mechanical break glass stopper designed to provide manual emergency access override when electrical systems fail or power is unavailable. The large format with integrated spacer fits standard commercial door frame geometries and installs into access control systems requiring mechanical backup activation. Deploy this where code-compliant emergency egress must function independently of electronic locks or system power—data centers, secure facilities, and commercial buildings with mandatory failsafe requirements.

Compatibility

The STI-4130EM integrates into access control architectures requiring mechanical actuation for emergency door release. It pairs with standard door strike assemblies and frame preparations typical of commercial access control installations. Verify frame width and strike type against your existing door hardware before ordering—the spacer design accommodates common frame geometries, but site-specific measurement is required.

Installation Notes

Comes complete with fixing kit for straightforward mounting. Installation follows standard door frame preparation procedures for mechanical strike and stopper assemblies. Ensure the door frame width matches the spacer dimension to avoid binding or misalignment. No electrical connection required—manual activation is purely mechanical, making it independent of power or network status.
