Harken Twisted Stainless Steel Shackles

The Harken Twisted stainless steel shackles used on Harken blocks are available separately. We have increased the range in both configurations and sizes. Harken Twisted Shackles belong to the Forged Stainless Steel shackle group.

The breaking strengths on the Harken Twisted 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.
