A small solution to a big problem. If you have outdoor pumps, fountains, or yard lights, the chances are, when it rains, your yard goes dark. That's because water seeps into the connection, causing a short that trips the GFCI outlet's protection switch. With Rain Block extension cord weatherproof gaskets, it can rain, it can pour and your yard will stay beautiful. Connect them to yard lights, Christmas lights, pumps, generators and more. The soft rubber compound keeps the rain and water out of your electrical cord and extension cord connections to keep the power flowing.
