Original Severne part for sails - for compatibility with booms fitted with an adjustable outhaul system. Simple yet high quality and well-engineered product made from premium nylon and marine-grade stainless steel.
Easy to fit (through the clew cringle/eyelet) and remove with 2 x Severne Hex4 Key/Tools or 2 x 4mm allen keys or one of each. Does not damage the sail. Should be able to be used on other brands of windsurf sail.
