## Questions & Answers

**Q: is this a surface mounted unit**
A: Negative:  Notice the two flares on the bottom.  If you need the surface mount order a different unit

**Q: do you sell a 30" version?  Thanks!!!**
A: The description says that it can only be cut 2 inches. How can you cut the 36 inch to a 30 inch? Why not create a drop down option for people to select the nominal length they want (i.e., 30", 32", 34"). That's what everyone else does on Amazon.

**Q: Why would an automatic door bottom seal be required?**
A: An automatic door bottom is required for a door with an uneven space in between the bottom of the door and the threshold. In my case, on one side of the bottom, there was a 1/4" gap, and on the other side, a 3/4" gap. A standard door jamb will not do the job you require. The automatic bottom has a spring and it presses the seal into place. Hope this helps.

**Q: Will this keep cigarette smell out?  We live in an apartment building and the smell in the hall can be very strong.**
A: If installed properly the unit makes a positive contact with floor and should stop odors from leaking in. It requires a wood door so the slot can be cut out for installation. The movement of air from your hall to room interior is more a matter of room air pressure differential. The foul air may still leak through door jamb gaps.
