Tecnoseal zinc plate anodes for rudders and trim tabs

Reliably protect rudders and trim tabs from galvanic corrosion: These disc anodes from Tecnoseal sacrifice themselves to keep your boat's expensive metal intact. The flat, round design sits discreetly on the surface and specifically diverts corrosion away from the protected components.

Tip: Replace the anode at the latest when it has corroded down to about 50% of its original volume – this ensures continued protection and prevents bare metal from being exposed in the water.
