Tylaska halyard shackles have the highest strength-to-weight ratio of any 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 molded thimbles. Lines can also be permanently spliced for a fixed halyard.
Tylaska CNC machines shackles from a solid block of aluminum. Type III hard coat anodizing protects against corrosion. Laser engraving identifies the product without sacrifice to strength or risk of corrosion. A new generation design of the H8 over our original H8 halyard shackles further improves corrosion resistance and provides more thimble bearing area for 2-1 applications.
