STI KIT-71101A-B Stopper Station Blue Back Box & Spacer Kit
Overview
The KIT-71101A-B is a blue back box and spacer assembly designed for surface-mounted Stopper Station installation on access control doors. This kit provides the structural frame, weather gasket, and cable entry management needed when mounting reader hardware directly to a door frame without a recessed enclosure. The 9VDC operating voltage aligns with standard STI Stopper Station push-button and reader power architectures, making this suitable for both interior controlled-access doors and weather-exposed exterior installations where a protective enclosure is required.
Compatibility
This kit is compatible with STI Stopper Station hardware, including the Stopper and Stopper II protective cover series. Verify the specific Stopper Station model (e.g., STI-1100, STI-1130, STI-1200, STI-1230, STI-1250, STI-3150) against your door frame dimensions and mounting method before ordering. The kit accommodates standard 7mm masonry drill holes for wall or door frame mounting and includes gaskets and cable entry inserts sized for typical access control wiring (RJ-45, twisted-pair, or coaxial runs).
Installation Notes
Mounting requires a 7mm masonry drill bit to secure the frame to the door frame or wall surface. Position the back box frame centrally over the protected device, mark and drill the four fixing holes, then secure with the provided wall fixings. Install the weather gasket between the frame and device to seal against moisture and dust ingress. For exterior installations or where cable entries are unused, install the spacer inserts to blank off unused holes—this prevents water pooling and debris accumulation around the cabling and frame seal. No power supply is integrated; the 9VDC rating refers to the Stopper Station device being protected, not the kit itself.
