## Questions & Answers

**Q: Can this be installed on a metal door?**
A: Yes, I was able to install it on a metal door, but my drill bit wouldn't go through the metal. After marking where the screws needed to be, I used a hammer and a long nail to make holes in the marked areas. Then I pulled the nail out after each hole was made. After that, I was able to use screws to attach the lock pieces. The lock is still firmly in place and works great.

**Q: entry is double door with one side always closed - can the U-11317 be used?**
A: It is a decision you would need to make. The mounting screw length is 1 3/4" for the side you would use to mount on the inactive door. You do not want the screws to go through  your door vs. it being installed on a door jamb frame.

**Q: My door frames are very thin. What is the width of the smaller piece that goes on the frame?**
A: The swing arm has to get screwed in the 2x4 studs behind the frame.

**Q: Seems this could be improved if the thumb lock was spring loaded? similar to the door reinf lock; particularly if you're trying to keep someone in**
A: The lock is not designed to keep anyone inside.  They are designed to keep someone from getting in and still allow you a small view of the other side of the door.
