STI-3150-ES Weather Stopper Ii Surface Mount Exit Device

Product Description

The SAFETY TECHNOLOGY INTL INC STI-3150-ES is a surface mount protective cover designed for exit devices and push buttons in commercial and institutional applications. Known as the Weather Stopper II, this cover shields exit hardware from moisture, dust, and environmental exposure that can cause premature wear or false activation. It is typically installed by licensed electricians or door hardware specialists as part of an access control or emergency egress system. The cover mounts directly over existing surface-mounted exit devices, providing a physical barrier without interfering with normal operation of the hardware it protects.

The STI-3150-ES is suited for environments where exit devices and push buttons are exposed to weather, humidity, or heavy-traffic conditions. Typical applications include exterior doors in commercial buildings, industrial facilities, schools, and healthcare settings where code-compliant emergency egress hardware must be protected from the elements. It is sold as a single unit and fits into the exit devices and push buttons product category.
