Ultimate Protector for Your Electric Cords and Cables: Wrap our handy cover around your cord connectors to protect them from rain, snow and ice! They’re water resistant to protect against electrical shorts and blowouts! Safety first! | PROTECTIVE COVER CAN FIT UP TO 12 GAUGE CORDS - The protector encasement has a length of 8.25 inches and a diameter of 2.75 inches. The wire entry points can accommodate up to 12-gauge cords while the large plug compartment can comfortably fit average domestic electrical outlet plugs including 3-prong plugs. The opening is only 0.4-inch, ensuring that the fit will be tight no matter the size of the cord. | HEAVY-DUTY PLASTIC WITH RUBBER SEALS - Durable and watertight, these connector covers are perfect for home and shop use. The high-quality molded plastic case has rubber seals on all edges with a solid and tight seal on wire entry points. No more water entering into the cord connectors and absolutely no more accidental unplugging! | CAPSULE-SHAPED PROTECTOR WITH SECURE CLOSURE - The capsule shape is a functional design choice. It allows water to just slide down from the protector's surface, adding extra water-repelling action. Not only that, but the protector has a double closure design. Rubberized snap closure ensures a watertight fit while the overlapping cover ensures that the protector won't accidentally open. | CAUTION: Outdoor extension cord plug protectors should not be submerged in water for a prolonged period. Even the most waterproof materials are not infinitely impervious to water. This is especially true with objects that have seams.
