STI borrowed from nature’s master builder, the spider, to create a web of protection from vandalism and accidental damage with these UL Listed wire 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.

Testimonials

"

When something works and does the job, I believe in telling somebody about it. Well, the STI Stopper II works! In fact, we have them over every one of our manual pull stations in every one of our 17 resident halls and in every other building on campus. In fact, we now have over a thousand Stopper IIs protecting us from false fire alarms. I’ve been here at Bryant University for 17 years now and they were here when I arrived. From what I’ve been told, we have been using STI Stopper IIs for more than 25 years. We know a great product when it can take the punishment and still provide the necessary protection.

A couple of years ago, our smoke detectors were getting beat up pretty bad. So on the basis of our success with STI Stopper IIs, we started installing STI Steel Web Stoppers over all our smoke detectors. No more problem!

Thanks, STI!
