Found a ridged orbital sander which had a worn down sanding backing (pads flew off while sanding / didn鈥檛 hold on that well if at all) so I ordered one of these replacement backings since it鈥檚 the same size and I couldn鈥檛 find the ridged ones.
My sanding pads now stick on like glue (that鈥檚 a good thing). Not sure how long it will last, but as of right now I鈥檓 very pleased with this product!
