STI borrowed from nature's master builder the spider, to create a web of protection from vandalism and accidental damage. This unit is constructed of 9-gauge steel wire with corrosion resistant polyester coating. Cover is for surface mounted smoke detectors.
As all STI protective covers, this Steel Web Stopper is backed by a three year guarantee against breakage in normal use. Installation and servicing are easy. Highly recommended for areas where abuse to smoke detectors is severe.
