This is a medium density, 3" foam & velcro sanding pad holder. It's great for hand sanding or to use for finishing on the lathe. You'll appreciate the easy-to-hold grip (especially for guys like me with arthritis). The holder measures 3" wide. 3" wide will work with any velcro hook sanding pad of 3" or more. Some folks use larger pads and wrap them up the sides or even put them on the top to use the rounded contours for sanding inside of bowls. You'll want to get a few of these. Quantity discounts available. Please call for details.
