Tylaska Main Halyard Shackle

Description of Tylaska Main Halyard Shackle

The Tylaska halyard shackles have the highest strength-to-weight ratio of any existing halyard shackles. They are made of high strength, missile grade aluminum with a unique locking tab to prevent the loss of the stainless cross-pin while the shackle is open. The all-metal thimble allows for use as a 2-1 purchase without the wear or melting that occurs with plastic molded thimbles. The clevis slot size is made to fit standard sail headboards without adding unnecessary weight. The strength and weight have been optimized by computer modeling and verified by numerous "make and break" tests.
