• FITS SURFPREP, UNEEDA, & MIRKA - Serious Grit 3" x 4" 6-Hole 40 grit hook & loop rectangle sanding sheets are compatible with the Surfprep 3x4 Electric Ray, Surfprep Storm, Uneeda Ekasand, Mirka DEOS 343, and any other 3" x 4" hook and loop detail sander.  These sanding sheets are ideal for sanding all surfaces, including wood, metal, drywall, epoxy, and painted surfaces.
• HOOK & LOOP-BACKED FILM SHEETS – Our sanding sheets are constructed with a heavy-duty polyester film backing material between the aluminum oxide abrasive grain and the hook and loop backing. This premium material creates a stronger disc, with more effective heat dissipation, and a better finish. These wet/dry discs are perfect for woodworking, auto body work including paint removal and wet sanding, and more.
• MORE DURABLE – Our sanding sheets are made with polyester film construction which makes them nearly impossible to tear. No more frayed or torn edges when sanding around corners.
• LESS CLOGGING – Our proprietary heat-treated zinc stearate anti-clog coating sheds dust before it has a chance to clog up your disc, making these discs virtually dust free when paired with a dust extractor or vacuum system.
• SMOOTHER FINISH – The film construction creates a flatter, stronger disc that produces a better finish vs paper, mesh, or net sanding discs. With our anti-clog coating, the entire surface area of the disc stays effective longer, which improves cutting power and leads to a more consistent swirl-free finish.
