Sta-Plug Emergency Plug.

Sta-Plug® is Forespar's 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
