Tips

For best results, position the clamp perpendicular to the joint and apply even pressure. The non-marring jaw pads protect delicate surfaces, but for extra safety on soft woods, use scrap wood between the jaws and the workpiece. Regularly clean the screw thread and lightly oil it to maintain smooth operation.
