## Questions & Answers

**Q: What exactly are you selling? Is this a bracket or a gas container or 3- 1 gallon containers**
A: Just the extension. For piggy-backing tanks on top of standard mount

A: This is the extension bracket so you can put two 3 gallon cans on the same mount

**Q: Can you have 2 containers. One on top of the other with this pack mount?**
A: This extender is designed to mount two 3 gallon tanks on top of each other or  beside each other however you desire, but you need the original mounting bracket for a single can to make this work
