The Eclipse ETBR T-Bar Clamp has an average clamping force of 2200 lbf. depending on the size. The drilled feet in the fixed head enable the clamp to be mounted to a workbench. The ductile head and slide are virtually unbreakable, whilst the steel bar offers maximum tensile and yield strength. The slightly tapered jaws enable perfectly parallel clamping and the fast action rolled thread applies pressure quickly and smoothly to the workpiece. Clamping Capacity: 42″. Bar Length: 48″.
