Review: Cut to size and you're good to go. - Perfect under door seal. Just make sure to measure and cut before installation or it will be a pain.
Review: 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.

## 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.
