## Questions & Answers

**Q: Which direction does the bar correctly extend to as designed?  The item picture shows right, but all but 1 of the customers pictures show left.**
A: The bar correctly slides to the right. There is a cutout in the metal for the handle knob to correctly tuck down into once correctly extended. If you were to turn it upside down, the slide knob would have to tuck upward and could easily shake loose.

**Q: Does this come with screws?**
A: Yes, it does! At least mine did.

**Q: How far out does the bolt slide?**
A: 1 " approximately.

**Q: how long are the screws**
A: 1/2 inch
