The Caldwell Casting/Performance Metals R1875A is a high-quality zinc anode designed specifically for rudder and trim tab protection on boats and marine vessels. This 1-7/8 inch anode provides reliable galvanic corrosion protection for underwater metal components in saltwater and brackish water environments.

Key Features:

• 1-7/8 inch diameter designed for rudders and trim tabs
• Manufactured from premium zinc alloy for maximum galvanic protection
• Helps prevent costly corrosion damage to steering components
• Easy to install with standard mounting hardware
• Suitable for saltwater and brackish water applications
• Meets military specification MIL-A-18001K requirements

Zinc anodes work as sacrificial metals that corrode preferentially to protect more expensive bronze, brass, and stainless steel components on your vessel's underwater hardware. Regular inspection and replacement of anodes is essential for maintaining proper corrosion protection and extending the life of your marine steering systems.
