Save weight, windage and money! If you sail a dinghy or sportsboat you can save up to 90% of the weight of a through deck block on your jib halyard, topping lift or other lines going through spars or decks. Smaller holes in spars, no corrosion from stainless steel in aluminium or carbon.
Choose the aluminium Exit Ring for aluminium spars and the titanium one for fixing to carbon. The Exit Ring is like a low friction ring that can be fixed into spars or decks. If the line running through it is only adjusted a little on the water or does not have much load when hoisting then the Exit Ring is perfect.
