Rod To Tape Type ‘A’ Clamps are designed to join various sizes of conductor tape to the earth electrode. Features: Material: High Strength Copper Alloy (body), Stainless Steel or Phosphor Bronze (bolt) Standard: BS:EN 62561-1 Class H, BS 7430 Tightening torque: 15Nm More Information: The clamps have a high resistance to corrosion and are mechanically strong to ensure a lasting connection. For installing lightning earthing system applications, We recommend the use of Copper earth electrode systems due to their inherent low resistivity and corrosion resistance.
