Longer lengthed Extended Seal Tubes are available 500mm, 1200mm, 2000mm, and 3000mm.
Kingsmill Double Flange Earth Rod Seals have been designed for use in concrete slabs with a nominal thickness of 300mm. They will withstand a pressure of up to 80psi (5.5 bar) and have been tested accordingly.
Benefits: Additional Earth Rods can be driven at a later date, with no additional parts or causing damage to the Earth Rod Seal.
