Tinned copper ground bus bars are used as central consolidation points for grounding kits. Pairs of pre-drilled universal lug holes allow for maximum usability. They are typically mounted on a wall or the interior or exterior of an entry room (shelter) where the exterior ground enters the building. The copper bars are coated in tin to prevent corrosion and elemental damage. Tinned bars are CSA certified and meet UL temperature standards. Measures 2” by 10”.
