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. This Universal Stopper is a clear, waterproof Type 3RX cover with a yellow horn housing, alarm, enclosed back box and open mounting plate. Cover is designed to comply with ADA and is less than 4 inches in depth. Other mounting options include a surface or flush mount cover. The cover is also available without a horn housing or message hood. Universal Stopper has the same footprint as the Mini Stopper®, but has a larger interior and can accommodate most dual action pull stations.
