In the Box:

• Performance Metals C1375A Shaft Anode (2 halves)
• Stainless Steel Hardware
• Plastic Retaining Washers

Key Benefits & Features:

• Superior Corrosion Protection: Made from a patented Navalloy® aluminum alloy (95% aluminum, 5% zinc, 0.02% indium) that actively prevents oxide layer build-up and provides more protection than traditional zinc anodes.
• Universal Water Compatibility: Engineered to perform effectively in all water environments—salt, brackish, and fresh—unlike zinc anodes which can become inactive in freshwater.
• Military-Grade Standard: Compliant with MIL-DTL 24779B(SH) military specifications, ensuring exceptional quality and reliability.
• Easy Installation: Features nuts pressed into the casting and bolts captured with plastic retaining washers for hassle-free assembly.
• Integrated Wear Indicator: Includes an exclusive, patented "red spot" wear indicator that appears as the anode corrodes, signaling when it's time for replacement.
• Environmentally Responsible: Contains significantly less zinc than traditional anodes, reducing pollution in marine environments.
• Longer Lasting Performance: Navalloy® anodes last 30-50% longer than zinc anodes, offering extended protection and value.
• Self-Cleaning & Reactivating: Remains active in freshwater and reactivates immediately upon re-immersion after air exposure, maintaining continuous protection.
• Lightweight Design: Significantly lighter than equivalent zinc anodes, contributing to reduced overall vessel weight.

Recommended For: 1-3/8" (35mm) streamlined shafts requiring premium corrosion defense.
