Sta-Plug Emergency Plug Sta-Plug™ is Forespar’s new form fitting emergency plug.  A soft cone shaped design allows it to easily fill the irregular shapes of hull impact breaches, as well as any round hole leak from a hose or through-hull.  Unique edge gripping riblets help hold the plug in a hole, keeping water out.  The riblets help Sta-Plug™ conform to the shape of the hole, sealing a leak near the edge where a tight fit is crucial, and holding the plug more securely in place. Different by design, Sta-Plug’s™ shape includes a series of concentrically larger riblets stepped along the length of the cone.  These riblets offer two big advantages over traditional straight edged emergency plugs: * They help Sta-Plug™ conform to the hole near the edge where a tight fit is most crucial * They help hold it more securely in place * Twist and compress by hand to insert into hole * Expands after insertion to hold in place Intended for temporary emergency use with continuous monitoring only, it gives the skipper greater peace-of-mind to allow them to focus on getting the boat to safety. Made from high density foam, Sta-Plug™ will remain soft and ready to go for years and will not mold or swell up like conventional wood plugs. * Can be cut with a knife to use in irregular shaped holes, or torn by hand near the riblets to make smaller diameter plugs for smaller holes   * Tearing at the 8th riblet creates a plug with a 2” diameter base * Made from high density foam that is not susceptible to mold or swelling * Bright orange color allows it to be quickly located in an emergency * Dimensions: 9” High x 5” Diameter at base * Made right here in the USA * Not for Fuel Leaks
