ABSTRACT:
This invention relates to a new and useful apparatus for protecting electrical wiring devices from rain, snow and other exterior elements. The apparatus consists of a molded top cover and bottom housing coupled together by a spring-type hinge. The molded cover and housing has a slot or channel therein for receipt of a polyurethane gasket. The housing has provisions for receiving a wire channel with circuit breakers or a plurality of molded receptacles coupled to a cable. The spring hinge snaps the cover and housing together so that the polyurethane gaskets mattingly abut each other and simultaneously surround any cables passing therebetween in such a manner as to inhibit moisture or other outside elements from entering the enclosure.
