The Norton back-up pad is specifically designed to be compatible with the Porter-Cable model #7800 drywall sander and Norton hook & loop sanding discs. By utilizing the hook & loop system, it offers a more cost-effective and efficient solution compared to using stock pads with glued abrasive. With the ability to use multiple sheets of sanding discs without the need to replace the foam back-up pad every time, it ensures convenience and savings. Attaching the sheets is a breeze with the easy-to-use Hook & Loop feature, and the foam pad securely fastens to the sander using the stock nut. Experience a significantly more economical option than using stock discs.
