The Sparcraft snap shackle was the first load-releasing shackle.
Its battle-tested design is built better and has become more reliable than ever before.

Investment cast in 17-4 PH stainless steel, these shackles are held to the highest aerospace standards. From alloys to heat treatment to tensile testing and processing, these products travel down the same production line as the highest quality components for military and aerospace applications. These shackles are still the standard whether racing in the America's Cup, around the world, around the buoys, or cruising up and down the coast.

SWL = safe working load. BL = breaking load
