Bow norman pin. Fits all Classic Boston Whaler boats from 9 - 17ft. Will also fit other boats. This is the "cleat" that is found in the bow fin area of most classic Boston Whalers. Made from high quality mirror polished 316 Stainless steel with a removable 2.5" threaded stud.  Each side of the pin is also 2.5". Some earlier model boats may have had pins with rounded ends.  These pins have hexagon ends.

Note:  Both sides of the pin completely unthread off of the stud.  Loosen both sides prior to installation so enough thread is exposed to reach through the fin.
