STI KIT-71101A-Y Yellow Back Box & Spacer Kit
Overview
The KIT-71101A-Y is a yellow back box and spacer assembly for STI stopper station installations. This kit provides structural mounting and spacing hardware needed when installing stopper stations on walls in surface or semi-flush configurations. The yellow color matches STI stopper station housings and helps maintain visual consistency across emergency communication deployments. Use this kit when your mounting surface requires standoff spacing or when you need a finished back box enclosure behind the stopper station.
Compatibility
This kit is designed for STI stopper station systems, including the Stopper II and Weather Stopper II product families. Verify your specific stopper station model against mounting documentation before ordering — different STI stopper models (such as the STI-1100, STI-1130, STI-1200, STI-1230, STI-1250, and STI-3150) may have different back box requirements.
Installation Notes
Position the back box frame centrally over the wall mounting surface. Mark the four fixing hole locations using the frame as a template. Drill mounting holes using a 7mm masonry drill bit. Secure the frame to the wall with the provided wall fixings. For surface installations, use the included spacer inserts to blank off unused cable entry holes and maintain proper spacing between the back box and wall surface. A weather gasket is included for outdoor installations or environments exposed to moisture — position the gasket over the device before securing the frame. Select the appropriate cable gasket for your wiring system before final assembly.
