Furse earth bars have a plastic channel base that is entirely corrosion proof, made from high impact uPVC unlike the traditional galvanized steel channel. The use of a modern polymer channel has also reduced the weight of these earth bars, making them lighter and easier to handle. Available as bare copper or tinned copper hard drawn bar. Pre-drilled fixing holes for ease of installation. Swan-Neck accessory available to facilitate the main earth bar connection. Standard height 90 mm, standard depth 77 mm. Tightening torque 20 Nm. Fix using countersunk wood screws 1½” No. 12 (Part no. SW110) and wall plugs (Part no. PS310).
