Tecnoseal Rectangular Zinc Plate Anode w/Inserts - 12" x 6" x 1"

The Tecnoseal Rectangular Zinc Plate Anode with Inserts is essential for saltwater corrosion protection, designed specifically to safeguard your vessel's submerged metal fittings from galvanic attack. Any serious boater understands the importance of zinc anodes, as they sacrifice themselves to protect critical components like through-hulls, propeller shafts, and engine cooling systems from the harsh effects of saltwater.

This 12" x 6" x 1" rectangular anode is made from marine-grade zinc and operates on cathodic protection principles, corroding preferentially to your engine block and fittings, thereby extending their lifespan. The integrated inserts facilitate secure fastening to existing hardware or custom mounting brackets, making installation straightforward and eliminating the need for improvised solutions.

Ideal for both freshwater anglers and coastal cruisers, the Tecnoseal zinc anode provides reliable, maintenance-free corrosion control. It is recommended to inspect the anode annually and replace it when it has corroded to approximately 50% of its original size, ensuring continued protection for your vessel's underwater metalwork.
