Durable PC Construction Crafted from quality PC plastic, this thermostat lock box offers strength and impact resistance to safeguard your thermostat from physical damage. Its large, clear cover delivers longterm durability, UV protection, and antiyellowing properties, maintaining visibility of thermostat settings over time. Built to last, it ensures reliable protection in both residential and commercial environments. Secure Ventilation Design Engineered with proper airflow openings, this guard prevents false temperature readings and maintains consistent thermostat performance. A secure lock mechanism with two keys protects against tampering, unauthorized adjustments, and accidental damage. The cover features a thickness of 1 mm (0.04 in) — thicker than standard models — delivering enhanced protection and stability. Once locked, the upper cover stays firmly fixed to the base, minimizing shake, shift, and unintended openings. Universal Fit This lock box is compatible with most thermostats measuring up to 5 in height x 7 in width x 2.3 in depth or smaller, and can be installed in a variety of settings including homes, apartments, schools, offices, hotels, churches, restaurants, factories, industrial spaces, and rental properties. Wherever installed, it guarantees dependable security and protection. Easy Installation Can be mounted directly onto the wall without removing your thermostat. Installation requires simple hole placement around the existing unit. The design supports both horizontal and vertical mounting options, making it adaptable to different thermostat shapes and layouts. Practical Applications In rental properties, prevent unauthorized changes to heating or cooling settings while ensuring tenants can still view the display. In offices or schools, maintain consistent climate control and prevent tampering that could disrupt productivity or comfort. In public spaces such as hotels, churches, or restaurants, protect thermostats from accidental damage while keeping usage simple for authorized personnel.
