Alpha Tools Rigid Backer Pad 4"
The Alpha Tools 4-inch Rigid Backer Pad is designed for wet polishing applications on stone and other surfaces. Its super-rigid, flat construction helps keep compatible polishing abrasives flat against the surface, reducing wavy finishes and surface distortion when polishing straight edges.
Ideal for stone fabricators, tile contractors, and restoration professionals, this backer pad is also useful for working in smaller areas such as corners and staircases. The hook-and-loop backing accepts compatible polishing pads, sandpaper, and felt wheels.
