3M Constant Force Springs are a range of solderless connections for use on lead or aluminium sheaths and copper screened cables - the 3M springs are easily applied by rolling onto the sheath connections, whereupon it continues to exert a constant pressure. 3M Scotch 23 self amalgamating tape is generally used to over tape the constant force spring once installed.

3M Constant force springs are solderless connections suitable for improving the earthing or grounding on lead and aluminium cable sheaths, cable screening tapes or wires and steel or aluminium armour wired cables.
