STI STI-9740 Exit Sign Damage Stopper Lock Strike
Overview
The STI STI-9740 is a protective strike assembly designed to shield exit sign hardware from accidental or intentional damage in commercial buildings, institutional facilities, and access control environments. Exit signs are frequent vandalism targets; this accessory deploys a welded gauge-9 steel wire frame with a corrosion-resistant polyester coating to prevent breakage and costly sign replacement cycles. Install it wherever exit signage faces risk—warehouse corridors, retail back-of-house areas, schools, or any space where sign integrity is a liability concern.
Compatibility
The STI-9740 is engineered as a universal protective cover for standard exit sign hardware and integrates with typical commercial door strike installations. It is compatible with electromagnetic and mechanical lock strike assemblies commonly deployed in access control systems. The frame measures 13.5 inches long × 10.5 inches wide × 2.75 inches deep, accommodating a broad range of exit sign models currently in service. Installation uses supplied anchors and fasteners; optional tamper-resistant screws and a matching drill bit are available separately for enhanced anti-vandalism protection.
Installation Notes
Installation is straightforward—mount using supplied anchors and standard fasteners into the door frame or wall surface surrounding the exit sign. The protective frame allows tool-free bulb access for maintenance and replacement without full removal. Note: the wire mesh construction may reduce light output; verify compliance with NFPA 101 emergency lighting requirements for your jurisdiction after installation. If deploying tamper-resistant hardware, use the optional matching drill bit to prevent removal by unauthorized personnel.
