Replacement drain plug for Prijon kayaks (imported from Germany). This is a completely unique drain plug, but reported to be same as those in Eskimo brand kayaks. NO BASE. The Prijon drain plug fits into a 3 screw base plate with a key-hole like shape opening, the round portion of the hole is approximately .75 inch diameter. Simply insert this plug into the base plate and turn closed. There is a tiny hole on the plug grip that can be used to tie the plug with a cord, as an retainer.
