STI STI-9601 Steel Web Stopper Low Profile Flush Mount
Overview
The STI-9601 is a protective steel web stopper designed to shield smoke detectors from vandalism, accidental impact, and misuse in high-traffic or institutional environments. The patented octagonal web design uses 9-gauge steel or medical-grade 304 stainless steel to create a barrier that is difficult to break while allowing unobstructed detector function. This low-profile flush mount fits nearly all smoke detector models on the market, making it a universal retrofit solution where detector protection is a priority.
Compatibility
The STI-9601 accommodates virtually all standard smoke detector models and mounting configurations due to its universal fit design. It is suitable for deployment in controlled indoor environments including institutional facilities, correctional settings, healthcare environments, and commercial buildings where detector damage or tampering is a documented risk. The guard does not interfere with detector sensitivity or alarm function when properly installed.
Installation Notes
Installation is quick and straightforward—the design allows simple removal for routine detector maintenance without tools or fastener adjustments. The low-profile flush mount configuration sits close to the ceiling or wall surface, minimizing protrusion that could invite contact or debris buildup. The guard is rated for controlled environments only, with an operating temperature range of -40°F to 212°F (-40°C to 100°C). Stainless steel models are recommended for hygienic or corrosive environments; standard steel models feature a corrosion-resistant linear low-density polyethylene (LLDPE) coating suitable for most indoor applications. The product carries a three-year manufacturer warranty against breakage under normal use.
