M&M Industries, Inc. manufactures each VZ-15 anode in the USA using high-purity MIL-A-18001 zinc alloy. M&M gravity casts every anode in a controlled U.S. foundry environment to maintain consistent quality, alloy chemistry, and corrosion protection performance.
The VZ-15 Bolt-On Zinc Sacrificial Anode measures 3-¾” x 17-7/8″ x 1-5/8″. VZ-15 carries a nominal weight of 15 lbs. M&M equips each anode with a galvanized steel core measuring ¼” x 1-½ x 12″. Each core incorporates two elongated mounting holes 5/8 x 1-¼” on 8-¾” centers to simplify installation and provide secure attachment.
