CMP CMC02AL Limited Clearance Shaft Anode Aluminum 7/8 Inch

The CMP CMC02AL is an aluminum limited clearance shaft collar anode designed to provide reliable galvanic corrosion protection for 7/8-inch propeller shafts in salt and brackish water marine environments. Its low-profile, split-collar design makes it ideal for installations where space around the shaft is restricted, allowing fitment in tight bilge and strut areas where standard shaft anodes won't clear.

Key Features:

• Material: High-purity aluminum alloy — the recommended choice for salt and brackish water use
• Shaft Diameter: 7/8 inch (22mm) inner diameter
• Dimensions: 1" (25mm) height, 2.12" (54mm) outer diameter
• Interlocking split-collar halves for easy installation and replacement without removing the shaft
• Allen head hardware included — slotted fasteners with bolt-retaining washers to prevent the anode from loosening or falling off underwater
• Extra alloy material around fastener areas for extended anode service life
• Designed for use in salt and brackish water applications

Also known as the Martyr C-2-AL, this anode is compatible with a wide range of cross-reference part numbers including C-2AL, C2AL, CMC2AL, AMDC-2, AMD-C-2, 00551AL, LC-0875-ALU, and RC-0875A. UPC: 628309191559.
