Dimensions and Model Selection

The MgDuff magnesium anode range includes two rectangular models with different body dimensions and mounting strip lengths. Body dimensions are specified as length × width × height.

MD79 (1798): Magnesium anode measuring 171 × 83 × 41 mm, with a mounting strip length of 230 mm and mounting hole spacing of 200 mm.
MD78 (1797): Magnesium anode measuring 305 × 76 × 32 mm, with a mounting strip length of 385 mm.

When selecting an anode, consider the overall body dimensions and mounting strip length. For the MD79 model, the specified centre-to-centre mounting hole distance is 200 mm.

Construction and Installation

Both models feature a rectangular magnesium body with an extended mounting strip. The strip extends beyond the anode body and provides the mounting arrangement for installation on the vessel.

Anode Body: Rectangular magnesium construction.
Mounting Arrangement: Extended strip.
Strip Length: 230 mm for MD79 and 385 mm for MD78.
Mounting Hole Spacing: 200 mm for MD79.
Installation Location: Boat hull or rudder.

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 MD79 and MD78 models are designed for hull and rudder protection. Their different body dimensions and mounting strip lengths provide two options for marine installations.
