M&M Industries, Inc. manufactures each VZ-9 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-9 Bolt-On Zinc Sacrificial Anode measures 2-7/8″ x 12″ x 1-½”. VZ-9 carries a nominal weight of 9 lbs. M&M equips each anode with a galvanized steel core measuring 3/16″ x 1-¼” x 9-½”. Each core incorporates two elongated mounting holes ½” x 1″ on 7-¾” centers to simplify installation and provide secure attachment.
