Clamp QLSCH series

Product overview
These QLSCH side cam clamps are cam-actuated devices that force the jaws forward for fast, secure workholding. Light-duty versions use spring-loaded jaws that retract when the cam is released for loading and unloading; standard versions retract the jaws by drawing them back when the cam is released. The handle position is adjustable to avoid interference. Precision-ground jaws permit clamping on finished surfaces. The clamp mounts from the top using two mounting holes.
