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
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.
