Compatibility and Fitment
This long dee shackle fits applications where the standard dee is too shallow. It suits webbing eyes, pad-eyes, chain links and small deck fittings that benefit from more internal length. Always check the bearing surfaces are smooth and confirm the SWL of the connected components is equal to or higher than this long dee shackle.
Compliance and Safety
Use within the stated SWL and avoid side-loading. Tighten the screw pin firmly by hand, then secure against loosening. Do not use for personnel lifting. Inspect regularly; replace the shackle if the pin binds, bends, or if the thread or bow shows wear.
Marine Applications
Because the long pattern increases reach, this long dee shackle works well for safety lines, block attachment, sail shade corners, tender lashing, fender lines and general purpose deck hardware. Rinse with fresh water after salt exposure. Additionally, periodic cleaning helps preserve the finish.
