Universal Stopper Cover protection

The STI-13210NR is a polycarbonate protective cover designed to shield dual-action pull stations, emergency buttons, light switches, keypads and intercom stations from vandalism and accidental damage. It mounts directly on a flat surface and meets ADA compliance, UL and cUL listings for indoor and outdoor use.

IP56 rating and temperature range

The cover carries an IP56 rating, meaning it resists dust ingress and strong water jets in exposed locations. It operates continuously from minus 40 degrees up to 250 degrees Fahrenheit, so it remains functional in extreme cold and high-heat environments. The polycarbonate shell provides impact resistance without obscuring the protected device.

Mounting hardware included

The package supplies the fixings needed for surface installation, removing the need to source separate screws or anchors. No additional software, wiring adapters or configuration tools are bundled — the accessory is purely mechanical and ready to fit on receipt.
