Easy Hook-and-Loop Attachment Our hook-and-loop feature makes pad attachment, removal, and re-attachment easy and facilitates use and re-use of the pad for the extent of the abrasive life. Our holders have T-shaped hooks of the type most commonly used in hook-and-loop applications. These holders grip the backings of hook-and-loop pads and provide a finer finish than do adhesive backed options. Use Scotch-Brite™ Materials Scotch-Brite™ surface conditioning discs and light grinding/blending products (sold separately) deburr, clean, blend, and finish a wide variety of materials. Using surface conditioning products with a 3M disc pad holder generates finishes suitable for paint.
