The Performax Ready-to-Wrap Abrasive Strips are designed for heavy-duty all-purpose sanding and are pre-cut for easy use with the Performax 10-20 Plus Drum Sander; the 120 medium grit is ideal for light dimensioning and surface preparation. Installing quickly and easily removed, the abrasive paper can be changed in just a few minutes. These strips are made with aluminum oxide and resin bonded for maximum grain retention. The heavy-duty X-weight cloth backing gives these strips added strength, while the anti-static design makes for easier dust pick-up. These abrasive strips have an open coat for non-loading properties and come 6 per box.
