UNIVERSAL EASY CLAMP
UNIVERSAL EASY CLAMP is the simplest system and it's considered standard for tools with R1 and American tangs.
A special insert with several grooves can be moved to the front or to the back to clamp R1 or American style punches.
Intermediates vary a lot ranging from 3.94'' (100mm) to 4.72'' (120mm). They may also have 2 different bending axis: Z1 at 0.28'' (7mm) and Z2 at 0.79'' (20mm) from the tang. Each intermediate can be used with ST60 standard clamp.
UNIVERSAL EASY CLAMP is equipped with a crowning wedge. By releasing the central screw and moving it to the left or to the right, crowning wedge is moved and intermediate height adjusted.
