Premium 1" Bow Shackle from Alfa Wheel Products. Constructed from 1" thick, ultra-high tensile strength steel, these Zinc Coated Bow Shackles resist damage even in the toughest elements. Features a threaded screw pin 1.14" in diameter ideal for both swift fastening and removal. As opposed to narrower D-Shackles, the larger "O" loops on these bow shackles are designed to take loads from multiple directions without developing unsafe side loading. Working load limit of 8-1/2 tons (18,500lbs). A generous 2.65" wide space inside the "O" shape accepts multiple connection points and larger straps or connections for all of your rigging, pulling and hoisting needs. Shackle measurement are shown on the pictures. Threaded pin is easily removable.
