The brand new ProGuard Orbital Backing Plate now features permanently adhered high quality dense hook material (the same material we use on the Rubber Pad Holders). This provides a much better mating hook and much more area of hook material. The color of the plate is white so you can tell it is the new and improved version. Low profile for improved control and a non-marking bumper for safe operation. The advanced design still allows for faster pad centering, and is perfect for quick and easy pad changes.
