Durable zinc sacrificial boat hull anode for bolt-on installation, a bolt-on M10 zinc anode designed to protect hulls from galvanic corrosion while remaining easy to fit and inspect.

• Material: zinc sacrificial anode
• Bolt-on configuration for simple fitting
• Designed to be part of a boat's maintenance routine
• Anode body dimensions: 8" (200 mm) hole centres for use with M10 studs
• Model: ZD78BM — compact, low-profile design
• Protects hull and below-waterline fittings from galvanic corrosion
• Most effective in saltwater environments

Check anode condition periodically and replace when heavily consumed to maintain effective corrosion protection. Do not paint or grease the anode; allow sacrificial contact with seawater for proper protection.
