## Questions & Answers

**Q: What are the dimensions of the pieces that attach to the door/wall?  I have a piece of trim to work with that is only 3/4" wide.**
A: I have about 3/4 of an inch to work with also. These did not work for me. The mounting brackets are an inch in width. I am curious if you have found another brand that has a narrower mounting bracket?

**Q: Does this come in brass or antiqued (I'm trying to find something to match what's in my motorhome)?**
A: You can always spray paint it

**Q: Do these help prevent the door from being lifted out of the track by a theif?**
A: This will not prevent the door from being lifted out of the track. Please review item S 4012.

**Q: I plan to install the inactive member to the door stop and the active member to the edge of the door. Will it work like I’ve described?**
A: There is a video clip and an instruction info on how to install. Careful for getting close to the glass if it is a sliding glass door
