Lightweight Universal Earthing Clamp (CCRU/B or P and CCNU/B or P) are clamps derived from the Universal Classic clamps (CCRU and CCNU) by adding an insulated handle (B) or a sliding cross rod (P) on the driving screw of the clamps.
These clamps can replace successfully clamps CLPR-16 or CLPN-30 in the standard structure of mobile short-circuiting devices.
