Break Glass Stopper®

Description

Accepted by many fire marshals, these versions of the world famous STI Stopper II® are designed for areas where a ”break glass” cover is specified, such as unsupervised areas. Each device consists of a red polycarbonate cover, mounting frame, a pane of single-strength clear glass (easily replaced when broken), a glass-breaking bar, screws and anchors for installation. Gaskets are also available to improve weather resistance.
