Nilight shackles are equipped with a 3/4inch pin, the perfect size to fit almost all bumpers (including aftermarket) with D-Ring anchor points. Each D-Ring is professionally powder coated to a matte or gloss finish, then topped off with a high quality anti-rust protective coating. The rounded design of anchor shackles and bow shackles allows them to take loads from many directions without developing significant side load. The larger loop shape of an anchor shackle or bow shackle does reduce its overall strength.
