This is one of the newest clamp from Gross Stabil. We all know how hard it is keep the bar clamp at the proper angle to prevent slipping and sliding. Now Gross Stabil has found the answer-change the angle of the clamp so that it will always be 90 degrees.
There are 4 angle inserts 22.5, 30, 45, and 60 degrees. Just pop them in or out for the miter you are clamping. Clamp up to 4" wide stock and can achieve up to 770 pounds of pressure. The non-marring, non-slip surfaces are polyurethane.
