## Questions & Answers

**Q: Will it work on a metal gate?**
A: Yes, I used 2 of these on metal gates. However, they both broke within 2 months, no more tension.

**Q: Will this support a 300lb wrought iron gate or would I need 2?**
A: I don’t know how you would attach to a wrought iron gate. That said I use it on a wooden gate that is about 40 lbs. works great. On a heavy gate you may need 2 would probably depend on how well your gate is balanced.

**Q: I already have it installed on an outside gate but now it is not closing it  ?so I want to know how to tighten it**
A: This spring pushes the gate closed, make sure you installed it so that when the gate is open the spring is compressed in rather than stretched out.

**Q: Can we use it on a gate on split rail fence? It is pretty heavy. We need to close pool permit**
A: This closer will close most gates.  If your split rail fence with a wooden gate is meant keep out small children, you may not meet the safety requirements for pool owners.  Check with your city planning department.
