MgDuff Zinc Hull & Rudder Rectangular Anodes, ZD Series

MgDuff Zinc Hull and Rudder Anodes – Rectangular, ZD Series, 200–457 mm

The MgDuff Zinc Hull and Rudder Anode is a rectangular sacrificial anode designed to protect metal components of boats against galvanic corrosion. Manufactured from zinc, it provides corrosion protection for hull and rudder applications by acting as a sacrificial component.

The range includes six models with different body dimensions and mounting configurations. Available versions feature fixed mounting hole spacings or elongated mounting slots with adjustable spacing ranges, allowing selection according to the required installation dimensions.

Technical Specifications and Available Models

The following table provides the body dimensions and mounting hole spacings for all six MgDuff zinc anode variants. All dimensions are specified in millimetres.

Dimensions and Model Selection

The MgDuff zinc anode range includes six versions with different body dimensions and mounting arrangements. Body dimensions are specified as length × width × height.

• ZD76ME (593070): Rectangular zinc anode measuring 200 × 65 × 32 mm, with 110 mm mounting hole spacing.
• ZD77E (593077): Rectangular zinc anode measuring 318 × 65 × 32 mm, with a mounting hole spacing range of 100–210 mm.
• ZD72B: Rectangular zinc anode measuring 457 × 102 × 64 mm, with 225 mm mounting hole spacing.
• ZD72BM: Rectangular zinc anode measuring 457 × 102 × 38 mm, with a mounting hole spacing range of 200–229 mm.
• ZD72BMLP: Rectangular zinc anode measuring 450 × 95 × 25 mm, with a mounting hole spacing range of 200–229 mm.
• ZD78B: Rectangular zinc anode measuring 305 × 76 × 32 mm, with 200 mm mounting hole spacing.

The ZD72B and ZD72BM models share the same body length and width of 457 × 102 mm but differ in height and mounting hole spacing. The ZD72B has a height of 64 mm and fixed spacing of 225 mm, while the ZD72BM has a height of 38 mm and a spacing range of 200–229 mm.

The ZD72BMLP version has a lower body height of 25 mm, a length of 450 mm and a width of 95 mm. It also features a mounting hole spacing range of 200–229 mm.

Mounting and Installation

The MgDuff zinc anodes are designed for installation on boat hulls and rudders. Their mounting arrangements vary depending on the selected model, with fixed mounting holes or elongated slots providing different installation dimensions.

• ZD76ME: 110 mm mounting hole spacing.
• ZD77E: 100–210 mm mounting hole spacing range.
• ZD72B: 225 mm fixed mounting hole spacing.
• ZD72BM: 200–229 mm mounting hole spacing range.
• ZD72BMLP: 200–229 mm mounting hole spacing range.
• ZD78B: 200 mm fixed mounting hole spacing.

When selecting a replacement anode, compare the overall body dimensions and centre-to-centre mounting hole spacing with the existing installation.

Galvanic Corrosion Protection

The MgDuff zinc anode acts as a sacrificial component, corroding preferentially to help protect other metal parts of the vessel against galvanic corrosion.

The range is designed for hull and rudder applications. The six available models provide different body sizes and mounting configurations for various installation requirements.
