7 SOLID Plates each 150mm. Solid Plate Cathode & Solid Plate Anode. Replaces old cell with no adjustments. This cable kit fits ALL AC & RP model female cables up to 25amp. AC15, AC20, AC25 (standard & self cleaning models).It is very important the cell leads are in good condition. Ensure crimping is done with a good crimping tool (do not use pliers). Place smaller heat shrink over metal crimps. Place large heat shrink over all the terminals. Ensure heat is applied evenly and no terminals are exposed after heating. If brass plugs are loose fitting then close the female plug slightly. You must have a tight fit. Solid plate is easier to clean. The calcium just falls off. Of the time compared to mesh cathode. In a cathode they last longer (as they have up to 3 times more material than mesh). There is no problem with using them in place of a mesh cell.
The cell will be replaced in the first 2 years if any manufacture defects are visible.
