Overland Vehicle System 3/4 Recovery Shackle in Gray is heavy duty forged D ring style shackle.  Each OVS shackle has a two stage powder coat.  First layer is Electrostatic plated and then a heavy duty Gray powder coat finish is applied which is the same process as the Original Automotive Manufactures do.  The shackle has multiple uses in recovery but the most common is affixed to a bumper however for more information see below for chart of uses with a shackle.  Highly recommend at least two shackles and tow strap when you're off road.
