Small Thermostat Protector

The Safety Technology International STI-9102 is a clear polycarbonate cover designed to shield indoor thermostats from vandalism and accidental damage. It mounts flush to the wall and operates reliably across a temperature range of -40 to 250 degrees Fahrenheit. Mounting hardware is included for immediate installation.

Facilities managers protecting climate controls

This protector suits schools, offices and public buildings where exposed thermostats risk tampering or impact. It is not intended for outdoor mounting or for devices that exceed the four-inch width and height footprint. Buyers needing a larger enclosure or a keyed lock mechanism should consider other options.

Included mounting hardware

The supplied fasteners allow direct flush mounting without sourcing separate screws or anchors. This reduces installation time and ensures the cover sits securely against the wall surface. No additional tools or accessories are required beyond standard household implements.

Questions about this item

What thermostat size fits the STI-9102 protector?

The STI-9102 is designed for small thermostats and measures 4 in wide by 4 in high with a 1 3/8 in depth, so verify your thermostat fits within those dimensions.

Will the polycarbonate cover withstand the same temperature range as my existing thermostat wiring?

The protector operates from -40 to 250 degrees F, matching or exceeding typical residential thermostat wiring ratings, so it will not degrade under normal HVAC conditions.

How can I confirm the cover is properly secured after flush mounting?

After installing the included mounting hardware, the clear polycarbonate cover should sit flat against the wall with no gaps, and the thermostat display remains fully visible through the cover.
