Scott Phillips, Host of The American Woodshop on PBS, interviews Bessey representative Tasos on the Junior line of Revo Clamps. K Body Revo Jr. is a mid-sized version of what made the full-sized Revo parallel clamp so great. These powerful jaws exert up to 900 lbs. of force with precision. Despite the enormous clamping force, these clamps are up to 30-40% lighter than all other parallel clamps claiming the 900-lb. rating. Bessey is known for its German engineering, German Steel and assembly in the USA.
