    Second-Best for Floating Homes (Use ZHC-42 Instead)

    Posted by Court Mast on Apr 15th 2024

    Hi All, This WELD-ON anode (ZHS-42) was used on floating homes for many years. As of 2024, a better system for attachment was devised: Two stainless steel bolts are now welded onto the copper wires, a one-time operation. Then the BOLT-ON version of these anodes (ZHC-42) is attached to the bolts with two stainless nuts. So the homeowner can now order the new anodes directly from RotoMetals, and install them using only a wrench. From that point on, here's no need to have a welder come out to replace the anodes.

    These large zinc bricks are the only anodes that work on concrete barges. Much better than aluminum
