STI 13420NW Universal Stopper Dome Cover, Enclosed Back Box and Sealed Mounting Plate, Label Hood with Horn, White

Protect critical security devices from vandalism, accidental damage and the elements with the Safety Technology International STI 13420NW Universal Stopper dome protective cover. Designed for fire and access-control environments, this security cover shields pull stations, keypads, intercoms and emergency buttons while allowing legitimate use. A built-in 105 dB horn sounds when the dome is lifted, alerting staff and deterring misuse so monitoring teams can respond before an incident escalates. Constructed from UV-stabilized polycarbonate with an enclosed back box, sealed mounting plate and NEMA Type 3RX rating, the cover stands up to outdoor exposure and severe indoor conditions. The ADA-compliant profile and high-strength continuous hinge provide reliable, long-lasting protection without blocking access. Compact dimensions (5.95" H x 4" W x 2.18" D) fit most standard pull stations and outlets, and the unit carries a 3-year limited warranty for added assurance. Ideal for schools, hospitals, retail and municipal buildings where security, surveillance and monitoring are critical—specify the STI 13420NW to reduce false alarms and protect life-safety devices.
