Hey woodworkers and DIYers! If your sander's backing pad is looking worn out or not holding sandpaper properly anymore, these replacement pads will bring your tool back to life. This 2-pack gives you spare pads for when you need them, compatible with popular models like Milwaukee 6021-21 & 6034-21, Rigid R2600 and R2601, Craftsman 315 series, and Ryobi RS290/RS280. The key thing to check before ordering: these are 5-inch diameter with 8 holes and use 4 screws with 1-1/8 inch distance between holes (center to center). The hook and loop surface is seriously grippy - way better than worn-out original pads - so your sandpaper stays put without slipping. The rubber backing is thicker and harder than cheap versions, meaning it won't flex too much and gives you smoother finishes. Installation is straightforward: just use your existing screws (sorry, no screws included) to attach it to your sander. The updated design provides stronger grip that actually holds the abrasive paper securely, even during aggressive sanding. Whether you're finishing furniture, smoothing drywall, or prepping surfaces for painting, having a fresh pad makes a huge difference in your results. These work with any standard 5-inch hook and loop sandpaper discs you already own. Much cheaper than buying a whole new sander, and honestly they perform just as well as OEM parts. Keep one on your sander and have a spare ready for when it eventually wears out. Your sanding projects will be so much smoother with these quality replacement pads!
