Review: Easy install, flexible cutting options (hacksaw OR tin snips) - These replacement door sweeps were much easier to install than I expected 👍 🔧 Installation • Pulled the old sweeps off and used them as a length guide • New ones slid right on with no fuss • Took just a few minutes per door ✂️ Cutting options (worked great for French doors) • We cut one with a hacksaw, as recommended • For the second sweep, we used tin snips instead and it worked perfectly • Tin snips were especially helpful because this was a French door where the trim between the doors doesn’t touch the ground • The outside piece fit neatly over the trim, while the inside covered the gap 🚪 Fit & function • Covered gaps well • Sealed nicely at the bottom • Everything lined up cleanly once installed Overall, these are very easy to use, forgiving if your door setup isn’t perfectly standard, and worked well with both a hacksaw and tin snips. If you’re replacing worn door sweeps, this is a straightforward, DIY-friendly option.
Review: Easy to install and works!! - For me, the vinyl-bottom door weather strip was a great improvement. It was simple to install, and after I did, it effectively sealed the space beneath my door and reduced moisture, dust, and drafts. I saw an instant improvement in insulation and general comfort, and the vinyl is flexible enough to fit the floor while yet feeling sturdy. It's not flashy, but for the price and ease of use, it fulfills my needs perfectly.

## Questions & Answers

**Q: Can anyone show me a product on Amazon I can order to cut this with please?**
A: I did mine with just a utility razor blade but as Warren said a hacksaw might be good, so I think it might be too soft for that.

**Q: Is the logistics updated in time?**
A: No

**Q: do you have brown color?**
A: Mine is 1 3/4 inches and it’s a tight fit, I’d guess it will work

**Q: Will this scratch interior wood floors?**
A: The bottom is flexible and soft. I don’t think it would.

### ⭐⭐⭐⭐ Functional, easy to install
*by R***D on August 24, 2025*

This sweep for a door does what it should do, keep outside air outside. It was easy to cut to length, but I had to remove two of the strips on the bottom for the door to fully close.
