  • Constant Force Springs are used to form a secure, solderless connection of an earth strap
  • For use on lead or aluminium sheaths and copper screened cables
  • These springs are manufactured in the UK from high tensile stainless steel
  • The ends of the springs are rounded to ease application and ensure safe handling
  • When applied they provide the necessary constant tension
  • Self amalgamating tape is often used to over tape the springs once installed
