Sea Shield Marine Divers Dream Bolt-On Hull Anode, Aluminum, 2-1/2" x 6" x 12"
The Sea Shield Marine ZHC-20-ALU Divers Dream Bolt-On Hull Anode is the definitive aluminum hull protection solution for commercial and recreational vessels. Die-cast to the highest military specification MIL-A-24779, this large-format aluminum anode measures 2-1/2" x 6" x 12" and features 5/8" slotted mounting holes on 12" centers for easy universal fitment without custom drilling. Built around a galvanized steel insert core, the ZHC-20-ALU provides superior bonding and a longer service life compared to anodes with uncoated cores—a hallmark of Sea Shield Marine's diver-focused engineering.
Aluminum alloy outlasts zinc by a significant margin and uses a less-toxic activator, giving mariners both economic and environmental advantages. Weighing 6.42 lbs, this anode offers substantial sacrificial mass to protect large vessel hulls in salt and brackish water environments. Designed in California and made in the USA, it is favored by professional service divers for its straightforward bolt-on installation and consistent, even burn rate. An excellent choice for commercial operators, yacht owners, and fleet managers seeking maximum hull protection between haul-outs.
