Martyr Anodes CMKK2Z Walter Keel Zinc Anode 3-1/4" x 3-1/4" x 1-1/8"

The Martyr Anodes CMKK2Z is a zinc keel anode designed specifically for saltwater marine applications. This Walter-style keel anode provides essential galvanic corrosion protection for underwater metal components on boats and marine vessels.

Key Features:

• Zinc alloy construction for saltwater use
• Walter keel anode design for efficient protection
• Compact dimensions: 3-1/4" L x 3-1/4" W x 1-1/8" H
• Protects propellers, shafts, rudders, and other underwater metals
• Easy bolt-on installation to keel area

Zinc anodes are the preferred sacrificial anode material for saltwater environments, where they effectively prevent galvanic corrosion by sacrificing themselves instead of more valuable metal components. Regular inspection and replacement of sacrificial anodes is essential for maintaining proper corrosion protection on marine vessels.
