PROFESSIONAL-GRADE tHERMOSTAT GUARD
Stop tampering, reduce energy waste, and lock in your settings with A COMBINATION LOCK OR KEY!
Trusted by facilities & property managers nationwide


Thermostat tampering isn't just an annoyance—it's a direct hit to your bottom line. Every unauthorized adjustment forces your system to work harder, accelerating wear and multiplying your utility expenses.
Offices become battlegrounds of hot and cold, causing systems to run constantly to compensate for manual overrides.
Unrestricted access allows guests and tenants to push HVAC units past their limits, risking premature equipment failure.
A single degree of unnecessary cooling or heating compounds rapidly, turning minor adjustments into major monthly financial drains.

Built to accommodate virtually all commercial and residential thermostats, the LockBoxPro backplate mounts securely to drywall, plaster, or electrical boxes without requiring specialized adapters or custom drilling.
Constructed from industrial-grade clear polycarbonate, the outer casing is engineered to withstand high-traffic environments, accidental impacts, and intentional tampering attempts without failing.
