The D-ring shackle is the mainstay of the off-roader's recovery bag. Used to join straps, snatch blocks, and any other assortment of recovery gear, the D-ring is a must-carry. They come in many sizes, but the 3/4-inch D-ring is most commonly included in most companies' winch recovery kits. Most recovery experts recommend keeping the strap ends on the shackle body as shown to prevent binding or loosening of the shackle pin. Use a pair of pliers, rock, or whatever you've got handy to really tighten the pin and ensure the shackle won't unfasten under load.
