Harken D-Shackle

The Harken Forged D Stainless Steel shackles used on Harken blocks are available separately.

The breaking strengths on the Harken Forged D Stainless Steel 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.
