High Heel plug, Low friction Delrin, for racing mast
Optiparts owns several moulds for producing custom end fittings.
All boom end fittings are made of high quality glass fibre filled nylon.
Unlike inboard boom-end fittings from other manufacturers ours have a firm
grip around the mast.This ensures that mast and boom turn together.
When retrofitting an old mast with a high heel plug first make sure the total
mast length will not exceed 2350 mm.
Diameters given are outside tube diameters.
