So you've got smoke detectors in high-traffic areas that keep getting bumped or messed with? This STI-9609 Steel Web Stopper is exactly what you need to keep them safe without blocking their function. It's UL listed and built from heavy-duty 9-gauge steel wire with this corrosion-resistant polyester coating that stands up to pretty much anything.
