40mm carbo block w/ shackle

The Harken 40mm Carbo Air Block and trigger snap assembly is custom made for McLaughlin Optimists. The block and shackle are permanently swaged together for a simple design. This new trigger snap is the smallest on the market and the block uses a unique center hole as the bail, allowing the total length to be less than 4 inches. This small size reduces the chance of being hit in the head by the block as you tack. Totally stainless even down to the spring. The trigger snap shackle easily attaches to boom bridal ring with one hand as opposed to most that require both hands free. As always Harken unconditionally guarantees their blocks.
