5" hook and loop backer with 5/8-11 thread.
Our white and yellow backing pads are the highest quality foam for extended life. The hook and loop backer is molded into the foam to insure solid adhesion even in high heat applications.
NOTE: high speed sanding can cause low spots in your metal surfaces quick and in a hurry, use caution when high speed sanding. Even pressure and constant movement across the panel or wheel is very important.
