Back Plate Adapter
Our Universal Back Plate Adapter lets you use a single, velcro pad holder for many types of polishers. If you own multiple polishers with different spindles, such as Porter Cable orbital, Flex orbital, or one of many rotary polishers, you can use a switch you 4", 5", 7" or 8" pads from one to another without changing to a different back plate.
If you own a Porter Cable and a rotary polisher, you can now use the same back plate on both. This adapter enables any diameter back plate with a 5/8" x 11 thread receptor to be used on polishers requiring a 5/16" diameter spindle.
