The Harken Forged Bow Shackles used on Harken® blocks
are available separately. The number on the shackle denotes the screw diameter
The breaking strengths on the Harken Forged Bow 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.
