These 3M™ Sanding Blocks are professional-grade tools that helps you achieve your best, fastest hand sanding work. The rubber has "give" to conform to sanding surfaces, keeping the sandpaper flat against the surface, ensuring uniform sanding performance. These pliable rubber blocks are designed to comfortably fit your hand. These sanding blocks feature internal attachment pins to hold sandpaper firmly in place on the block. The rubber blocks can be used for wet or dry sanding. These sanding blocks will make sanding faster, easier, and more effective. Works with a 1/4 sheet of any  9" x 11" sandpaper.

Directions for use:

1. Lift the rubber flap on one end of the sanding block to expose the metal spikes. Cut sandpaper into 1/4 width strips, 2-3/4" x 8-1/2". Place sandpaper abrasive side up between the flap and spikes. Use caution as metal spikes are sharp.

2. Press flap down to perforate and secure sandpapers.

3. Wrap sandpaper around the bottom of the block and repeat steps 1 and 2 on the other end of the block, keeping sandpaper taut.
