This stand is designed to be used with the Pearl Cube Cajon. It can be used for many other percussion instruments. The measurement of width of each panel is 15.25". The cube cajon's width is 12.5", so that is the maximum width that an instrument can be in order to fit inside this stand. There are rubber pieces where the instrument makes contact to prevent damage during vibration. The two stands together come out to be 19" high. The Smaller section at its lowest point is 7" and the taller is 11". This is a fantastic portable stand for any hand percussion player.
