The Contour Sanding Grip pads are double ended to make it super easy to sand convex or concave surfaces. Each pad has a convex profile at one end and a matching concave profile at the other end along with a narrow flexible section in the middle that can also be used for sanding. Each durable, flexible rubber grip allows you to easily sand concave or convex profiles without distorting the radius. The non-slip rubber pad prevents abrasive slippage and hand fatigue. This set is perfect for woodworkers, auto body, metal work, arts, crafts or even around the house. Designed to work with standard 9” x 11” sanding sheets or 3” wide sandpaper rolls (sold separately).This package includes 6 contour grips with the following inside/outside diameters: 1/4'', 3/8'', 1/2'', 5/8'', 3/4'' and 7/8''. Diameters sizes are molded into the rubber pad for easy selection.
