Description
The CMT-Z04AA is a marine-grade aluminum hull anode with integrated aluminum strap, designed to provide reliable galvanic corrosion protection for hull-mounted systems and bonded underwater metals. The aluminum strap ensures proper electrical continuity while offering a corrosion-resistant mounting solution.
Built from high-quality aluminum alloy, this anode delivers long-lasting protection in saltwater and brackish environments, outperforming traditional zinc in most real-world marine conditions.
