"Levitons full line of Raintight and Weather Resistant Covers are ruggedly constructed to seal out moisture, dust, debris and insects, while providing easy access to receptacles. Industrial Grade covers are designed for rugged conditions. Their sturdy, gasketed covers mount vertically or horizontally. Leviton makes two innovative Raintight While-in-Use Covers: telescoping and metal. Designed for decks, patios, porches and similar locations, theyre more than a match for the vagaries of weather. The telescoping cover sports a low-profile when in the contracted position, while the metal cover features a self-closing lid made of powder-coated cast zinc. Leviton Weather Resistant Covers let homeowners use power tools, trimmers, sprinkler systems and pumps with confidence and safety. Theyre also ideal for outdoor security, landscape, accent and holiday lighting."
