## Questions & Answers

**Q: Will this work without having to cut away the molding to ensure the wall and door are completely flush?  Can't do that with a barrel bolt...**
A: I know you asked this back in May but I figured I'd make a suggestion anyways as it seems other people are having an issue like this. All you have to do if you have a molding that isn't flush is add a wood shim of equal thickness to the door side to make it flush with the molding. Just drill holes thru your shim using your latch base as a template. You may need longer screws for door side once adding a shim. You can even paint it to match door color as best you can. I personally think its a lot easier on the eyes then cutting into your molding....

**Q: My molding frame around my door is 1/2 thick on the outer edge. Do you think it will mount well or need 'rigging'?**
A: You will need to do some rigging on the frame or put some steel washers on the door to cover the thickness gap

**Q: Most modern entries have jambs and interior side mouldings that aren't flat, how could it mount?**
A: You can put this on a block of wood. You mount the wood to the wall then this to the wood... paint it and make it look nice. Honestly it would be better that way for security reasons

**Q: Can these be installed on the inside of an rv door?**
A: Well you see the design of the latch/lock. There are screws that screw in the empty holes and as long as you have sufficient door material and wall material (thickness) to hold these screws in place, you are good to go and can install them.  If however, your screws would not set far enough into the wall and into the door, or door and door facing, whatever, then the screws will simply pull out when any pressure is put against the latch.
