Net Abrasive Sheets Lasts 3X longer than sandpaper. Made with an open weave structure that minimizes "loading up" of the material, all but eliminating clogging even when used on painted wall preparation jobs. Unlike sanding screens, the variable net structure leaves no sanding pattern or uniform scratch lines that show up after finishing. Precut in standard 3-5/16" x 11-1/4" rectangular sheets for conventional and dust-free hand sanders. Standard size to fit all Hyde Vacuum Sanders.
