Review: World of difference! - Perfect fit! So I decided one day that I was going to replace all my doors weather stripping. And didn’t know there were different sizing and materials. So I bought 2 other types before finally deciding to try to match what I pulled off. I bought 2 different foam sizes that didn’t fill the gaps. As you can see in pictures with light around the door that was 2 sizes of foam together and it still didn’t fill the gap. My old weather stripping was scratched up by my dog. So one day I just ripped all the doors stripping out. Some wouldn’t close and some weren’t big enough. I was worried when I finally bought this because I doing know the size I ripped out. But I remember it looked like this! Well this one fits perfectly. There is no adhesive like the foam but that’s ok because it’s slides into the “kerf” which I had to Google that word. And not all my doors have a kerf. But my back door was killing my with the sun coming through and the heat and everything else that comes with a gap. The durability on this stuff is great! Nice and firm. Worked well with my kerf just pushed it on it and slid my hand down to make sure it went in. And I tell you it’s night and day the difference. I don’t hear the dogs barking or kids playing. The air is cool in my kitchen. No bugs coming through. And it’s easy to remove and replace. Easy to cut with simple scissors. I think I used my kids school scissors. The shipping was next day. And I’m happy! Just buy this. It should fit if you pulled out one like it. My door closes fitted doesn’t slam. The dogs can’t just push it open when it’s unlocked. I feel like I got a new back door!

## Questions & Answers

**Q: how is this product secured to kerf?**
A: The installer pushes the product into the kerf.  There is no need for glue as the fit is very snug. It is a very easy project.  As you remove the original weather stripping and replace it with the new, 'what goes where' becomes obvious. It only requires a bit of strength to butt the strip in evenly along the strip length.

**Q: How does this compare against the Q-lon weatherstripping? I have to replace some sections torn up by my cat but want to make sure it doesn’t look bad.**
A: More durable than Q type.

**Q: Is there a special tool for cutting the kerf in older door frames?**
A: I don’t know of such a tool.  I suppose one could use a cutoff tool but it would be difficult to do.

**Q: Is this a thicker strip? Or standard size? Looking for something thicker.**
A: Standard size.

### ⭐⭐⭐⭐⭐ Weather Stripping; Mystery and Triumph
*by S***S on December 3, 2024*

When I first opened the package, I was filled with a sense of purpose. Weather stripping! My drafty doors and windows didn’t stand a chance. Or so I thought. The instructions were simple enough—or would have been, had the second half not mysteriously disappeared into the void. (Apparently, the packaging said “1 of 2, do not separate,” but I didn’t see it until I had already committed to the separation.) No matter! I am a modern problem solver. Surely, I could figure this out. What followed can only be described as a three-act drama: Act I: Discovery. I unrolled the stripping, marveling at its spongy promise. It was like the duct tape of weatherproofing: flexible, versatile, and oddly sticky. Act II: Confusion. I began applying it… somewhere. The adhesive side fought valiantly against its backing, and once victorious, clung mercilessly to anything nearby. My hands? Yes. My cat? Unfortunately. The doorframe? Occasionally. Without part 2 of the instructions, I had to make some educated guesses. By the end, my windows were sealed, my door frame was cushioned, and my soul was thoroughly humbled. Did I also accidentally weatherproof my own sock to the floor? Yes. Yes, I did. Act III: Acceptance. Once installed (or at least stuck in several places), it worked surprisingly well! Drafts were blocked, and my house felt cozy for the first time in ages. Sure, the process was chaotic, but isn’t that just life sometimes? Overall, this weather stripping gets a solid 5 stars for effectiveness, durability, and the opportunity to grow as a person. However, if you’re missing part 2, consider calling in a professional—or at least hiding the cat. Bonus Tip: Double-check your packaging before separating parts. Some mysteries are better left unsolved.
