CMP CMC04AL Limited Clearance Aluminum Shaft Anode 1-1/4 Inch

The CMP CMC04AL is a limited clearance aluminum shaft anode engineered for marine vessels where space around the propeller shaft is too restricted for a standard full-size shaft anode. Designed as a sacrificial anode, it protects the propeller shaft from galvanic corrosion caused by exposure to salt water and brackish water environments.

Key Features:

• Aluminum construction — ideal for use in salt water and brackish water applications
• Limited clearance design — fits installations where standard shaft anodes cannot be used due to space constraints
• Split interlocking halves — installs directly around the shaft without removing it from the vessel
• Includes Allen head bolts with lock washers and bolt retaining washers for secure, vibration-resistant mounting
• Sized for 1-1/4 inch inner diameter propeller shafts
• Part of the CMP Group CMC anode series, a trusted name in marine corrosion protection

The CMC04AL is a drop-in sacrificial anode solution for boaters who need dependable corrosion protection in tight shaft clearance situations. Simply clamp the two halves around the shaft and tighten — no shaft removal required. Replace when the anode is approximately 50% consumed to maintain continuous protection.
