STI 13320NR Universal Stopper with Horn Enclosed Flush Back Box, No Label Included, Red

Protect critical access control and emergency devices with the Safety Technology International STI 13320NR protective cover — engineered to prevent accidental or malicious damage while allowing immediate, legitimate activation. This Universal Stopper security cover is molded from UV‑stabilized polycarbonate (PC) for reliable indoor/outdoor durability and long-term color retention. The enclosed flush back box design — available with a horn option — secures pull stations, keypads, intercoms and emergency buttons and simplifies wiring and installation. At a maximum protrusion of 4 inches and with low-profile or dome styles, the STI-13320NR minimizes tampering without restricting operation, supporting fire alarm, access control and monitoring workflows. Its red, high-visibility finish helps first responders and personnel quickly locate emergency controls, and the “no label included” configuration makes it easy to apply custom signage that matches your site’s surveillance and monitoring standards. Ideal for commercial buildings, schools and industrial sites that require robust vandal and environmental protection.
