Full Circle International Inc. SD80-5 8-3/4- Level360 Sanding Disc 80 Grit. Fits the Radios 360 Sanding tool. The ability to change directions quickly without having to lift the pad off the wall is a huge advantage over the conventional method of sanding drywall. The detachable foam disc forms to the wall, providing a smooth, even finish. Unlike the conventional sand pole, this foam disc wears evenly, greatly increasing the life of the tool. Both the foam pad and the sandpaper utilize hook-and-loop backing, making for easy replacement. Loop backed sandpaper firmly attaches to the foam disc, preventing debris from collecting behind the sandpaper, and eliminating a major cause of streaking. Sanding with the Radius 360° is up to three times faster than using a conventional sand pole, with consistently superior results.
