Diablo 2-3/4 x 5-In. Reusable Hand Sanding Block is for sanding both flat and contoured surfaces with ease. This versatile sanding block features two sides: a cushioned side designed for controlled material removal on contours, and a dense side that provides aggressive material removal on flat surfaces. The innovative Hook & Lock backing ensures a secure and removable attachment to the SandNET sheets, which are crafted from nylon with a clog-reducing design to minimize dust build-up. These SandNET sheets are reusable and simple to clean by shaking, vacuuming, or rinsing, making your sanding tasks more efficient and less messy. The package includes one sanding block, two 80-grit sheets for coarse removal, two 120-grit sheets for fine preparation, and one 220-grit sheet for an ultra-fine finish. Model Number: DFB234DUOH01G
