This is the length of stainless steel studding, stainless steel insert and retaining nut that we use at the bottom of our fins when the ballast is to be removable. The stainless steel insert is bonded into a round keyhole in the fin and prevents the studding from pulling out. The retaining nut fits into a counterbored hole in the underside of the ballast. It is better that the counterbored hole has the brass seat, item INS-seat, fitted to resist wear.

740 mm length x 150 mm chord at top x 75 mm chord at bottom, with lower 220 mm parallel, fitted with internal structure, surface is slightly irregular due to post curing of the whole fin after bonding, leading and trailing edges require finishing

740 mm lang Profiltiefe oben 150 mm, 75mm  unten, die unteren 220 mm sind parallel. Die Oberfläche ist leicht unregelmäßig durch Nachhärtung der ganzen Flosse nach der Verklebung von Vorder-und Hinterkante. Eine Endbehandlung der Oberfläche ist noch erforderlich.
