The A. N. Wallis tinned earth bars have been used on a variety of high-profile projects, this is partly due to the fact that our tinned earth bars offer excellent resistance to water corrosion, and subsequently provide enhanced conductivity. The tinning process means that copper bars are protected from oxidisation. Our Tinned earth bars have a typical copper purity content in excess of 99.9%

The A. N. Wallis single disconnecting link tinned earth bars are mainly used to offer a temporary break in the connection to the earth, allowing the inspection and testing of multiple earth rods / systems while disconnected from the lightning and earth system.

Special earth bars manufactured to customer requirements are also available.

Recommended fixing by countersunk wood screw 1 1/2″ x No. 12 and No. 12 wall plug.
