A first of its kind, the patented Skimmer PlugTM is superior to any other skimmer closure or winterizing device on the market, being more affordable, as well as much easier to use. The Skimmer PlugTM fits all OEM skimmers without the need to replace the original skimmer faceplate. With no installation or tools required, the Skimmer PlugTM securely fits into the skimmer opening using our exclusive RovasealTM thermo insulated expanding layer to plug and grip the faceplate, creating a 100% air/water-tight seal. Ice is no match for the Skimmer Plugs rigid outer plate, providing a durable and secure layer of protection through the winter.
