3M™ Cartridge Roll 341D, 80 X-weight, 1/4 in x 1-1/2 in x 1/8 in, 100 per case

3M™ Cartridge Roll 341D gives you easy access to small, hard-to-reach spaces for sanding and finishing. As the outermost abrasive layer wears down, the cloth backing frays to expose fresh abrasive layers for continued cutting action.
