Sti STI-9105 Safety Technology International -9105 Thermostat Protector with Key Lock

The STI STI-9105 Thermostat Protector with Key Lock from Safety Technology International is a physical security enclosure designed to shield wall-mounted thermostats and energy sensors from unauthorized adjustment, deliberate tampering, and accidental damage in commercial and institutional environments. Molded from clear polycarbonate, the cover maintains full visibility of the thermostat's display and controls while physically blocking access to dials, levers, and other adjustable elements. A keyed lock assembly ensures that only authorized personnel—facility managers, HVAC technicians, or building operators—can open the cover and make legitimate setting changes. The design is well suited for high-traffic areas such as offices, schools, healthcare facilities, hotels, and multi-tenant buildings where comfort control abuse or energy waste is a concern. Ventilation openings integrated into the frame allow unrestricted airflow to the thermostat or energy sensor, preserving accurate temperature sensing without compromise. Included spacers accommodate surface-mounted thermostat configurations, making the unit broadly adaptable across common installation types. Installation is straightforward and requires minimal time, reducing labor burden for professional installers and maintenance teams.

Key features & benefits

• Tamper-Resistant Enclosure — An inner wall structure physically prevents contact with thermostat dials and levers, deterring unauthorized occupant adjustments and protecting settings established by facility management.
• Keyed Lock Assembly — A lock-and-key mechanism ensures only credentialed personnel can open the cover, providing a controlled access layer that supports building energy management and security protocols.
• Clear Polycarbonate Construction — The molded polycarbonate cover provides high-impact resistance while maintaining complete visibility of the thermostat beneath, allowing status checks without requiring the cover to be opened.
• Unrestricted Airflow Design — Frame perforations allow air to circulate freely around the thermostat or energy sensor, ensuring that the protective cover does not interfere with accurate ambient temperature readings.
• Surface-Mount Compatibility — Included clear spacers extend the cover's compatibility to surface-mounted thermostat installations, giving installers flexibility across varied wall and junction-box configurations.
• Quick Professional Installation — The straightforward mounting design minimizes installation time, making the unit practical for large-scale deployments across multi-room or multi-floor commercial projects.
• Broad Application Suitability — Appropriate for offices, schools, hotels, healthcare facilities, and other commercial or institutional settings where thermostat security and energy control compliance are priorities.
