Technical Specifications and Available Models

Dimensions and Model Selection

The MgDuff magnesium hull and rudder anode range includes three models with different body dimensions and mounting arrangements. Body dimensions are specified as length × width × height.

• MD72B: Rectangular magnesium anode measuring 457 × 102 × 64 mm, with a mounting hole spacing of 229 mm.
• MD77EURO: Rectangular magnesium anode measuring 318 × 65 × 32 mm, with elongated mounting slots providing a specified hole spacing range of 110–210 mm.
• MD78B: Rectangular magnesium anode measuring 305 × 76 × 32 mm, with a mounting hole spacing of 200 mm.

The MD77EURO and MD78B models have the same body height of 32 mm but differ in length, width and mounting arrangement. MD77EURO measures 318 × 65 mm and features elongated mounting slots, while MD78B measures 305 × 76 mm and has a specified mounting hole spacing of 200 mm.

When selecting an anode, check the overall body dimensions, mounting hole spacing and mounting arrangement against the required installation dimensions.

Construction and Mounting

These MgDuff anodes feature a magnesium body with mounting openings for installation on the hull or rudder. The mounting arrangement varies depending on the selected model.

• MD72B: Two circular mounting openings with 229 mm centre-to-centre spacing.
• MD77EURO: Two elongated mounting slots with a specified mounting spacing range of 110–210 mm.
• MD78B: Two circular mounting openings with 200 mm centre-to-centre spacing.

The MD77EURO model offers a wider range of mounting positions through its elongated slot design. The MD72B and MD78B models have fixed mounting hole spacings.

Galvanic Corrosion Protection

The magnesium anode functions as a sacrificial component, corroding preferentially to help protect other metal components of the vessel against galvanic corrosion.

The MgDuff MD72B, MD77EURO and MD78B models are designed for hull and rudder protection. Their different body dimensions and mounting configurations provide options for various installation requirements.
