Rubber retainer strap holds the band in a neat, folded position when in storage. Foam pad protects the workpiece from the metal parts on the clamp mechanism. Stores excess band to eliminate mess. Includes 1 x rubber band retainer/no-mar pad and 4 x 90° corner clamping cauls. Can be used with the Rockler 25mm (1) x 4.5m (15) Band Clamp (sold separately) .
