Industrial STI-3150 Stopper Series II

Industrial STI-3150 Stopper II Weather Stopper is a protective overcover designed for Stopper II and Weather Stopper pull stations, engineered for indoor and outdoor use to guard the activation point from weather, physical damage, and tampering while helping prevent false alarms. Crafted with a clear polycarbonate cover and a gasketed spacer, the unit is UL/cUL listed and rated IP54, delivering a weather‑resistant seal (NEMA 3R equivalent) when mounted on a smooth surface. The enclosure measures 7 inches high by 5 inches wide by 5.2 inches deep and is intended to fit over most manual pull stations, with STI-3150 variants including models without horn with spacer and fire label (and other label configurations) depending on the specific model. This Stopper II cover is designed to extend the life and reliability of weather‑exposed signaling devices by providing robust protection without obstructing the activation area.
