Martyr Anodes CMT21 Tear Drop Zinc Hull Anode 5" x 2" x 0.8"

The Martyr Anodes CMT21 is a tear drop shaped zinc hull anode designed to provide superior corrosion protection for underwater metal components in saltwater marine environments. This streamlined anode configuration is engineered to minimize drag while maximizing galvanic protection for hulls, rudders, trim tabs, and other submerged hardware.

Key Features:

• Tear drop profile reduces water resistance and turbulence
• Zinc alloy formulation specifically engineered for saltwater use
• Compact 5" length x 2" width x 0.8" height dimensions fit tight spaces
• Cast from high-purity zinc meeting military specification MIL-A-18001K
• Pre-drilled mounting holes for secure installation
• Provides sacrificial protection against galvanic corrosion

Martyr anodes are manufactured to stringent quality standards and use alloys that meet or exceed all military specifications. The tear drop design makes this anode ideal for applications where hydrodynamic efficiency is important. For brackish water applications, consider aluminum anodes; for freshwater use, magnesium anodes are recommended.
