This indoor/outdoor polycarbonate cover helps protect devices such as dual action pull stations, keypads for entry systems, intercom stations, emergency buttons, electrical light switches, duplex plugs, etc. The strong, durable construction takes the toughest knocks while it guards against accidental or intentional physical damage.
The STI-13020CG is a clear, flush mount cover with a green horn housing, alarm and custom label. Cover is designed to comply with ADA and is less than 4 inches in depth. Universal Stopper has the same footprint as the Mini Stopper®, but has a larger interior and can accommodate most dual action pull stations.
