U-Bolt Shackle Straighteners

U-Bolt Shackle Straighteners

thingiverse

If you're forced to use cheap U-Bolts that come with the Overly-Wide, flat, "Oblong-holed" Shackles, which always seem to allow the cheap U-Bolts to spread apart under use, these Shackle inserts will add a surprising amount of lateral strength to keep the free ends of your U-Bolts straight and aligned. These fit 5/16ths Inch, by 1-3/4ths, by 4-3/16ths Inch (7.95 mm X 44.45mm X 106.36mm) U-Bolt shackles, but can be scaled to fit larger or smaller sized U-Bolts.
