MGDuff Pear Anode ZD77 - Zinc 2.25kg

The MD Duff Zinc Pear ZD77 is one of the most common sizes of the bolt-on anodes and, with its universal 200mm hole centre, will retro-fit many other makes and sizes. It can be used in a host of areas around the hull and rudder or 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 to be protected (for example, the engine or stern tube). It can also be surface-welded directly to the hull, rudder or any metal surface that needs cathodic protection.
