STI borrowed from nature’s master builder, the spider, to create a web of protection from vandalism and accidental damage with these UL Listed smoke detector guards. They are constructed of 9-gauge steel wire with corrosion resistant polyester coating or 9-gauge stainless steel wire. Together, they cover virtually every smoke detector model available today.
