Protect critical fire and access-control devices from vandalism, accidental damage and harsh environments with the Safety Technology International STI-13520FR protective cover. This Universal Stopper cover combines durable polycarbonate construction with a self-contained 105 dB audible alarm and NEMA Type 3RX/IP56 weatherproofing to keep pull stations, keypads and emergency buttons secure indoors and outdoors. The low-profile, ADA-compliant design measures under 4 inches deep and includes an enclosed back box and open mounting plate for fast, universal installation on most dual-action pull stations. UV-stabilized material and gaskets guard against dust, water and UV degradation while the high-strength continuous hinge resists repeated use.
