Thermostat Protector Dome Shape


Once you set your circular-type thermostat and install this super tough cover, there are no more worries about tampering, vandalism or accidental damage. It is molded from clear, thick polycarbonate material and is installed with tamperproof screws for added protection.

As all STI protective covers, the Tamper Stopper Thermostat Cover carries a three year guarantee against breakage in normal use. It is UV-stabilized and slots around the circumference allow air to circulate freely for proper operation of the thermostat. Installation is quick and easy. The cover is shipped complete with tamperproof spanner screws, anchors and a spanner bit. STI also offers Thermostat Protectors for vertical-type thermostats, mini-thermostats and energy sensors.
