Camp Zinc Barrel Collars for Shafts

Camp Zinc barrel collars for shafts are zinc shaft anodes (also called shaft zincs or barrel collar anodes). They protect a boat's propeller shaft and nearby underwater metal from galvanic corrosion. The zinc is sacrificial. It corrodes in place of the shaft and other metal parts, so the more valuable components last longer.

Key Features:

• Zinc construction for sacrificial cathodic protection in marine environments
• Barrel collar design clamps around the propeller shaft
• Marine zinc anodes in this category are typically made to the MIL-A-18001 zinc anode specification
• Made in the USA by Camp Company

Installation and Care:

• After installing a new anode, check propeller clearance before starting the engine.
• Do not paint the anode. Paint blocks the zinc from working.
• Inspect the anode regularly. Anodes subject to cavitation wear out faster.

Replace the anode before it is fully consumed so the shaft stays protected. Pick the variant that matches your shaft diameter.
