Earth bonds & clamps
TSC-0912 - 09.10.12
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.
