A riser for typical sized Volume ( 10.1" x 3.8" x 0.5"). It helps prevent the back-and-forth rocking that sometimes occurs when mounting pedals of this size. If you are drilling the pedal into your board and screw fastening it down, it also serves as a giant washer!
Includes the acrylic riser + 6 screws.
