Norton 9-Inch Back-Up Pad For A290 Hook-and-Loop Discs and Porter Cable Drywall Sander 7800 (Pack of 1)

The Norton 9" hook-and-loop drywall sanding backup pad for Norton A290 paper-backed discs provides extra support, enabling the use of heavier pressure without tearing the disc. This pad mounts to the Porter Cable model 7800 sander (sold separately) with a hook-and-loop mounting system, ensuring quick and easy installation and removal.

Back-up pads provide the backing surface for attaching a sanding disc to grinders, orbital sanders, polish sanders, and other grinding machines. The back-up pad composition and design affect results. For example, a firm pad provides a more aggressive cut. A medium back-up pad provides greater flexibility. A slotted hub draws cool air behind the disc to reduce generated heat on the workpiece. Sanding discs attach to the back-up pad in a variety of ways, such as with locking nuts, adhesive, or a hook-and-loop system for quick disc changes that don€t require tools.
