Native Super Seal Scupper PlugsThe Super Seal Plug (sold in sets of two) is a multi ribbed scupper plug that creates a high pressure seal and prevents water from entering through the scupper holes. If you need to drain the hull, the easy pull handle lets you quickly remove the plugs or return them to the scupper hole. They are low profile to prevent line snags but can be modified to use a tether.
