I bought a set of 36" sliders (rated load: 250 pounds) for a wall mirror (36" x 72"). I needed it to slide because it is above the dash panel in my garage. Beside him is the same mirror, fixed flush with the wall. Now the mirror on the sliders completely covers the mirror next to it, giving access to the control box. Surprisingly VERY SMOOTH! I used 3/4" plywood (62 lbs), mirror (46 lbs) and accessories (7 lbs). Total weight without slider: 115 lbs! I HIGHLY RECOMMEND THIS PRODUCT!
