Tylaska’s halyard shackles have the highest strength-to-weight ratio of any existing halyard shackle on the market. A captive 17-4PH stainless pin makes for trouble-free operation. The all-metal machined line thimble allows for use as a 2-1 purchase without the wear or melting that occurs with plastic moulded thimbles.
The term stainless steel is used to describe a family of about 200 alloys of steel with remarkable heat and corrosion resistance properties. Its distinguishing characteristic is the high amount of chromium. Stainless steel contains a minimum of 10.5% of chromium that improves its corrosion resistance and strength.
