H290 17.5" x 2.75" P40 Grit Aluminum Oxide File Sanding Sheets (50 Pieces) by Norton®. Outfit your sanding board with the quick and cool cutting power of this H290 coarse grit paper file strip, which features a P-graded A/O grain. The long-lasting strip resists tears thanks to a durable E-weight backing, while the non-loading, water-based stearate minimizes loading. An open coat design pairs with the durable materials for increased sanding productivity, especially when used for body filler, fiberglass or composite sanding. Attach the strip to a sanding block to tackle heavy material removal applications.
