## Questions & Answers

**Q: What size/width slot is required for pushing the plastic edge into?**
A: Not sure what width you are asking about. If you are talking about the channel it goes into it is pretty much standard size which is a groove you press the flange into. The only width/gap you need to make sure of is the door to the frame which is about 5/8. Close your door and measure the spacing. I used this to replace the original of 37 years old and it fit like a charm. Very satisfied, looks good and will stop any air leaks. Hope this helps.

**Q: The groove you press the flange into should be installed first, because regular doors do not have it, right?**
A: Actually our door had a groove and we just replaced the old stripping that the cats had shredded. Easy and worked great
