Harken Captive Halyard Shackle

The Harken Captive Halyard Shackles used on Harken blocks are available separately.The breaking strengths on the Harken Captive Halyard Shackles are derived from tests that support 80% of the length of the screw pin that is unsupported, which is similar to the area of a post in a block. Safe working loads are no more than half the minimum breaking strength.
