Moveable Ring for grooming arms

An add-on piece to suit any tubular steel grooming arm that is 7/8" square up to 1" size. The stainless steel version only goes 7/8" tube.. the new nylon version fits 7/8"( normal size on our tables) and 1" arm. I'm hoping to get more metal ones in soon.. slide on to your top or side bar, unscrew knob to move, tighten knob to stop. great for adjusting & adding side tie on bars without that option
