Designed for connection of flat tape conductor to an earth rod. Corrosion resistance, conductivity and mechanical strength are
essential considerations in clamp design to ensure an earthing system remains operative for many years. All Furse earth rod clamps
have high strength copper alloy bodies and screws e.g. aluminium bronze, phosphor bronze etc., commercial brass is not used
– Tightening torque 15 Nm
