• Zinc plates (sacrificial anodes) protect boat lifts from galvanic corrosion and electrolysis by eroding instead of your lift's structural metal

• Helps with electrolysis 

• For most lifts, it is recommended to hang one anode per 500 lbs of lift capacity or place them on areas directly exposed to the water.

• How to Install & Maintain

Attachment: Hang the zinc plate over the side of the boat lift and secure the stainless steel cable to the lift's frame, ensuring a solid metal-to-metal contact 

Maintenance: Inspect the zinc anode periodically. Because it is a sacrificial metal, it is supposed to deteriorate.

Replacement: Replace the zinc plate once it has reduced to about half of its original size to maintain continuous protection for your lift.
