STI KIT-102722-E 5/8" Spacer for Stopper® Stations

Overview

The KIT-102722-E is a 5/8" spacer kit engineered for STI Stopper® Station electric strike assemblies. This accessory solves a common installation problem: maintaining consistent air gap between the strike mechanism and the door frame during mounting. Without proper spacing, strike engagement suffers and door closure becomes unreliable. The spacer ensures frame-to-strike dimensional accuracy, critical for 9VDC Stopper® systems operating in commercial and institutional access control deployments.

Compatibility

The KIT-102722-E is designed for STI Stopper® Station strike assemblies and Stopper II variants. Install it during new door frame preparation or retrofit applications where legacy frame conditions have shifted. The spacer maintains alignment across standard commercial door thicknesses and frame profiles common in office buildings, schools, hospitals, and secure facilities.

Installation Notes

Position the spacer between the strike mechanism and door frame face before final fastening. Use the 7mm masonry drill holes specified in STI installation documentation to secure the frame assembly with provided wall fixings. For surface-mounted Stopper II configurations, insert the spacer gasket first, then layer the frame and fasteners to create a weathertight seal. If cable entry holes remain unused, apply the blank-off inserts to prevent water ingress and dust accumulation — important for outdoor or high-moisture environments.
