STI-7521OB Protective Cabinet with Open Backbox and Thumb Lock, Clear Polycarbonate

Protect critical fire, security and surveillance devices from vandalism and accidental damage while keeping them fully visible for monitoring and inspection. The Safety Technology International STI-7521OB protective cabinet is a durable cabinet/enclosure designed with a clear polycarbonate cover and an open backbox so you can easily mount it over previously installed pull stations, sensors or control panels. At 10.88" H x 8.88" W x 3.7" D and constructed from impact-resistant PC material, it balances low-profile mounting with rugged protection.

An exterior thumb lock provides quick authorized access and the additional eyelet accepts a secondary lock or tamper-evident seal for elevated security needs. UL and cUL approvals mean the enclosure meets industry safety standards, and the included gasket and mounting hardware speed installation in corridors, lobbies, and equipment rooms. Ideal for facilities managers, integrators, and security teams needing reliable device protection without obscuring visibility, the STI-7521OB helps maintain uninterrupted monitoring and compliance.
