This tough, locking, cover helps stop vandalism, damage and tampering of mini thermostat or energy sensor.

Molded of clear, 1/8″ thick, heavy-duty polycarbonate material, this protective cover is recommended for areas where abuse is a problem. This may include vandalism, accidental damage or costly, annoying tampering by employees and others. Especially useful where thermostats are located in public areas, the device is easy to install. Holes in the frame allow air to circulate freely for proper operation of protected thermostats or energy sensors. An inner wall on the frame prevents tampering with dials and levers.

Backed by a three year guarantee.

As all STI polycarbonate covers, this super tough unit is backed by a three year guarantee against breakage and damage in normal use. For added protection against abuse, it comes complete with a lock and key assembly. The Thermostat Protector is shipped complete with all mounting hardware.
