Description
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
• This product should only be used for its intended purpose in sailboat applications
17-4 PH: Info and Care
17 equals Chromium content and 4 equals Nickel Content. PH stands for precipitation hardening. This grade is known for strength and heat tolerance, NOT corrosion resistance. Though it has some corrosion resistance properties it will require routine maintenance in saltwater environments. If you use a product made of 17-4 PH, you need to follow a routine maintenance schedule.
