STI KIT-71101A-E Orange Back Box & Spacer Kit
Overview
The KIT-71101A-E is a back box and spacer accessory kit designed to support STI Stopper Station lock/strike installations. This kit provides the structural mounting platform and spacing components required when integrating electric strike hardware into door frame and wall configurations. The orange-finished back box handles cable entry management and hardware alignment for 9VDC strike systems, making it essential when retrofitting existing installations or deploying new access control infrastructure where surface-mount clearance or wall prep demands dedicated backing infrastructure.
Compatibility
This kit is compatible with 9VDC lock/strike systems within the STI Stopper Station product family. The back box and spacer are engineered to work with proper Stopper Station strike assemblies. Verify your specific strike model against STI's current compatibility matrix before ordering, as back box selection depends on the exact strike form factor and the installation surface (drywall, masonry, or metal stud). If you are integrating this kit into a larger access control system, confirm that your strike voltage matches the 9VDC requirement.
Installation Notes
Installation requires a 7mm masonry drill bit for mounting hole preparation. Position the back box frame centrally over the device to be protected, mark the four fixing hole positions, drill using the 7mm bit, and secure using the wall fixings provided. For surface installations, use the spacer inserts to blank off unused cable entry holes and to accommodate the wiring system in use. Cable gaskets must be selected and installed to match your specific wiring configuration. Ensure the orange back box is positioned before strike assembly to simplify wire routing and gasket placement.
