Caldwell Casting/Performance Metals R3750Z 3-3/4" Rudder/Trim Tab Zinc Anode

The Caldwell Casting/Performance Metals R3750Z is a marine-grade zinc anode specifically designed for rudder and trim tab protection. This 3-3/4" sacrificial anode provides essential galvanic corrosion protection for your boat's critical steering components in saltwater and brackish water environments.

Key Features:

• 3-3/4 inch zinc anode designed for rudder and trim tab applications
• Sacrificial zinc material protects more noble metals from galvanic corrosion
• Prevents costly damage to rudders, trim tabs, and associated hardware
• Marine-grade construction for reliable performance in harsh saltwater conditions
• Precision casting ensures proper fit and optimal electrical contact

Zinc anodes work by being more electrically active than the metals they protect, causing them to corrode preferentially and preserve your boat's expensive components. Regular inspection and replacement of sacrificial anodes is essential for proper corrosion protection. This anode is specifically shaped and sized for rudder and trim tab mounting applications.
