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, surface mount cover with a red horn housing, alarm, fire label and red conduit spacer. Cover is designed to comply with ADA and is less than 4 inches in depth. Other mounting options include a flush mount cover or a waterproof Type 4X enclosed back box (Type rating pending). 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.
