## 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

### ⭐⭐⭐ Review
*by W***S on 27 February 2024*

I purchased this product for the door seal in hopes of improving insulation in my home and reducing heating costs. However, my experience with this product has been less than satisfactory. The installation process was as straightforward as advertised. Cleaning the door and applying the seal seemed simple enough, and initially, I was hopeful that it would effectively seal the gaps around my door frame. Unfortunately, my optimism quickly turned into disappointment as I noticed that the adhesive backing failed to provide adequate adhesion, despite meticulous surface preparation. Even after following the instructions diligently, the seal began to peel off within a short period, rendering its effectiveness questionable. Here is a pros and cons list according to my experiences: Pros: - Easy installation with self-adhesive backing. - Flexible material suitable for various sealing purposes. - Can be customized to fit different door and window sizes. Cons: - Poor adhesion despite proper surface preparation. - Doubts about long-term durability and effectiveness. - Some users experienced issues with adhesive quality and seal longevity. In summary, while the door seal offers convenience and versatility, its shortcomings in adhesion and durability raise concerns about its effectiveness as a long-term solution for insulation and weatherproofing needs.
