STI STI-9742 Exit Sign Damage Stopper Wall Mount
Overview
The STI STI-9742 is a wall-mounted protective cage designed to shield exit signs from accidental impact and intentional vandalism in commercial corridors, stairwells, and emergency egress routes. Built from gauge 9 welded steel wire with a corrosion-resistant polyester coating, it serves deployments where exit sign damage translates directly to compliance risk and replacement cost. Dimensions of 13.5 inches long × 10.5 inches wide × 2.75 inches deep accommodate a broad range of standard exit sign models.
Compatibility
The STI-9742 fits standard commercial exit sign installations across most manufacturers' current form factors. It mounts directly to walls using supplied anchors and fasteners, compatible with typical drywall, concrete, and metal stud framing. No modification to the exit sign itself is required — the protector installs as a standalone cage around the sign body. Integrators deploying this alongside door strike systems or emergency access control should note that the cage does not interfere with standard electrical feeds to the sign.
Installation Notes
Installation is straightforward: mount the cage using supplied anchors and standard fasteners. Heavy-duty tamper-resistant fasteners are available separately if your environment demands anti-intrusion hardware. Because the cage partially blocks direct light output, verify that projected luminance still meets NFPA 101 exit sign brightness requirements for your jurisdiction before final acceptance — test with a light meter in the exact installation context. The cage allows easy bulb replacement by sliding it aside or removing it temporarily; plan maintenance access accordingly in high-traffic zones.
