STI KIT-102722-W 5/8" Spacer for Stopper® Stations
Overview
The KIT-102722-W is a 5/8" spacer engineered for STI Stopper® station installations. This accessory maintains the precise gap between a door frame and strike mechanism that keeps the Stopper® functioning reliably in high-traffic access control environments. If your Stopper® station strike sits flush or misaligned with the door frame, the mechanism won't release cleanly — this spacer corrects that. It's factory-matched to work with 9VDC Stopper® systems and integrates into the existing mounting footprint without modification.
Compatibility
Designed for STI Stopper® and Stopper® II station families operating at 9VDC. Confirm your specific Stopper® model (e.g., STI-1200, STI-1230, STI-1100, STI-1130 for standard Stopper II, or STI-1250, STI-3150 for Weather Stopper II variants) before ordering, as frame geometry varies between product lines. The spacer adapts to surface-mount and recessed installations provided the mounting surface and strike depth allow the added 5/8" clearance.
Installation Notes
Position the spacer between the frame and strike according to your Stopper® installation instructions. The 7mm masonry drill holes referenced in Stopper® II documentation remain the same; the spacer fits within the existing fastener pattern. No additional wiring or power draw — the spacer is a passive mechanical component. For Weather Stopper II deployments, confirm that gasket and cable entry clearances remain adequate with the spacer installed.
