STI STI-4130 Break Glass Stopper Large with Spacer

STI STI-4130 Break Glass Stopper Large with Spacer

Overview

The STI-4130 is a large-format break glass stopper assembly with integrated spacer, designed to trigger emergency access control and door release functions in life safety applications. This accessory provides a mechanical emergency egress solution where personnel need rapid, fail-safe activation of exit doors or fire alarm integration points without power or network dependency. The spacer component maintains proper clearance and structural alignment with compatible STI strike mechanisms and access control frames.

Compatibility

The STI-4130 integrates with STI emergency keybox and door release systems. Verify compatibility with your specific STI access control hardware before ordering — compatibility extends to STI-series door strikes and emergency egress hardware in the same product family. Contact the manufacturer or a system integrator for confirmation on your exact installation.

Installation Notes

The assembly ships with a complete fixing kit for mounting to standard door frames and strike hardware. Installation requires basic hand tools and straightforward mechanical fastening — no special electrical configuration needed for the stopper itself. Ensure proper spacer alignment with the strike mechanism to guarantee reliable glass-break activation of the connected door release. Verify clearance between the glass and frame edges before final installation to prevent binding or malfunction during emergency use.
