CM CAMLOCK Plate Lifting Clamp 1-1/2 Ton 3/4″ $200

This is a CM Camlock Plate Lifting Clamp.  It will lift up to 1-1/2 tons in weight and 3/4″(20mm) in thickness.  It has CE 2000 stamped into it.  I am thinking this is the Model Number though I cannot find any reference to a CE series on the internet.  It appears to be in good shape and everything on it seems to function ok.
