## Questions & Answers

**Q: Is this a pancake anode? Does it have the top and the bottom anode?**
A: I ordered two not being sure what the configuration was.  These are pancake anodes - flat on one side and domed on the other.  They apparently come in pairs where a QTY of 1 gets you two anodes connected together with a screw that can be easily separated to expose the flat side.  I received two pairs with a QTY of 2.

**Q: The listing says this is for a cmr 5, but the picture shows a cmr 3.  which is it?**
A: It is a CMR5. It is 5" in diameter and 3/4" thick. I put them on my Bennett trim tabs, replacing the old original factory anodes. Fit perfectly.

**Q: Will this work to prevent galvanic corrosion between steel and aluminum that is not in the water?**
A: I don’t believe it will

**Q: How many pieces come with an order, 2?**
A: Yes. 2.
