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; 1500-lb. nominal clamping force.
