Magnesium disc anode for protecting submerged metal components against galvanic corrosion. The anode gradually wears away as it protects the connected metal. Check it regularly and replace it when significantly depleted. This single disc measures 70 mm across and 13 mm high, with an 8.5 mm mounting hole. Compare the dimensions and mounting arrangement with your existing anode before ordering. Install with clean metal-to-metal contact and leave the anode unpainted. Specifications Material: Magnesium Outside diameter (Ø): 70 mm Height (h): 13 mm Recess diameter (Ø1): 22 mm Mounting-hole diameter (Ø2): 8.5 mm
