Proprietary rubber band made from a tough, tear-resistant material, with 3 extra-strength splines. Large, ultra-grip clamp pads hold tight without slipping. Pivoting jaws accommodate angled pieces and allow full pad contact regardless of stock thickness. Tension is adjusted by stretching the clamp further into the material. Wood glue flakes off the rubber band material for easy clean up. Proprietary rubber band made from a tough, tear-resistant material, with 3 extra-strength splines.
