Vario REVO clamps, like this 40" one, replace the fixed jaw with a wider sliding jaw that can now be placed anywhere on the bar with a push of the release button. Additional clamp jaws with spindles and Vario sliding jaws are available to double or triple the clamping positions on your longer K-Body REVO clamps to save shop space, time and money. Replaceable protection caps protect delicate surfaces, and the comfortable two-component composite handle with soft plastic inserts offers a more comfortable grip. And the clamp easily converts to a spreader without tools. 40" clamping capacity, 3-3/4" throat depth; 1,500-lb. nominal clamping force.
