The MD Duff Zinc Pear ZD77
This is one on the most common sized, bolt-on anodes and with its universal 200mm whole centres will retro fit many other makes and sizes. It can be used in a host of areas around the hull and rudder or may be wired internally to protect equipment.
This anode is normally fitted with through-hull bolts and then earth wired from the internal studs to whatever is required to be protected – Example: the engine or stern tube. It may also be surface welded directly to the hull, rudder or any metal surface that ultimately needs cathodic protection.
Use of a backing sheet is recommended
