Run wires around your house and yard like a pro. Don't let snow, rain, or even the water sprinkler stop you! These outdoor cord protectors are made of heavy-duty molded plastic with rubber linings that lock moisture out. The capsule shape itself helps repel water away from the protector, ensuring that water won't build up on the surface. Aside from the rubberized snap closure, these cord plug protectors also have an overlapping cover that can serve several purposes. The most obvious purpose is as a secure cover that will prevent the protector from accidentally opening. Operate cordless power tools around your shop or yard without the fear of accidentally yanking the plug out of the connector. A not so obvious purpose of overlapping cover is for child and pet-proofing extension cord connectors.
