Product Overview

Aluminum Bennett Trim Tab Anode, BNT1A.

Anode selection guide:

  • Zinc anodes for saltwater
  • Aluminum anodes for saltwater or brackish water
  • Magnesium anodes for freshwater only

Advantages of aluminum anodes:

Used in saltwater, aluminum anodes last longer and protect better than zinc. Used in brackish water, aluminum anodes are superior to zinc which can “passivate” and not work at all, or magnesium anodes, which corrode to rapidly. Aluminum anodes are also lighter than zinc and do not contain cadmium, a substance of environmental concern.
