The Harken HR D Stainless Steel shackles used on Harken
are available separately.
The breaking strengths on the Harken HR 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.
The high-resistance shackles are marked "HR."
