Description

STI STI-9602 Steel Web Stopper Low Profile Surface Mount

Overview

The STI-9602 is a surface-mounted steel web stopper designed to protect smoke detectors and access control hardware from vandalism, accidental impact, and abuse in controlled environments. Built from 9-gauge steel with a patented octagonal web-like design, this low-profile guard delivers impact-resistant protection without requiring permanent modifications to mounting surfaces. Deploy this where smoke detector protection is critical — facilities prone to intentional or unintentional strikes, high-traffic areas, or institutional settings where hardware durability directly affects code compliance and system reliability.

Compatibility

The STI-9602 is designed with universal fit — the octagonal web structure accommodates nearly all smoke detector models currently installed across commercial and institutional buildings. Surface mounting allows retrofit installation on existing detector housings without modification. Suitable for integration into access control system architectures where detector tampering poses a risk to fire safety integrity and system credibility.

Installation Notes

Surface mount installation is quick and simple — no specialized tools or torque specifications required. The design permits straightforward removal during routine detector maintenance, avoiding costly downtime for service calls. Operating temperature range spans -40°F to 212°F (-40°C to 100°C), suitable for controlled indoor environments including mechanical rooms, warehouses, and climate-controlled facilities. Not rated for outdoor exposure. Stainless steel (304 medical grade) variants available for hygienic or corrosion-sensitive environments such as food production, healthcare, or chemical storage areas. Standard steel models feature a corrosion-resistant linear low-density polyethylene (LLDPE) coating for durability in dry indoor settings.
