## Questions & Answers

**Q: What is the faceplate dimension?**
A: 1 X 7 1/8

**Q: Can I get this with the deadbolt on the bottom**
A: Yes you can. You just have to search for it like I did.

**Q: Can the same lock be change between left and right hand?  I used to able to open and flip it. That's all it needs.**
A: Yes,  you just need to open it up and reverse the striker.

**Q: Can this replace the standard deadbolt that is separate from door knob, without modifications to the door?**
A: Now I am not expert locksmith, but if you are asking: Can you replace a dead bolt lock system with a Mortise lock system with major alteration on the door. The 2 system are so different the entire mortise lock system slides into the heading of the door while your existing deadbolt system only has a hole just for the dead bolt to move in and out. In conclusion I would not attempt do the swap, the door needed to have been design for mortise lock system
