STI STI-9105, Thermostat Protector with Key Lock, Flush Mount, Clear

Secure critical temperature controls without compromising performance or aesthetics. The Safety Technology International STI-9105 Thermostat Protector is a lockable protective cover designed to prevent tampering, vandalism and accidental adjustments to thermostats and energy sensors. Molded from clear, heavy-duty polycarbonate (PC), the flush/wall-mount enclosure maintains visibility of controls while a built-in interior barrier blocks access to dials and levers. Strategically placed ventilation holes allow free airflow for accurate monitoring and uninterrupted HVAC operation, and the unit’s compact footprint (approximately 5.5" W x 5" H x 3" D) fits most standard devices. Supplied with a key lock and full fixing kit, the STI-9105 retrofits quickly to reduce installation time and service disruption. Ideal for schools, healthcare facilities, multi-tenant buildings and other spaces requiring robust security and reliable climate control, this Protective Cover helps protect your investment and maintain environmental stability.
