Draft free
Item as described and keeps draft out

Not cheap for a bit of plastic but did the job.
My external door was rotting from the bottom due to the rain hitting the sill and bouncing onto the bottom of the door. Bought this and, although it's not proven yet, it's obvious that the water won't be able to dampen the wood so it is definitely going to do the job. Fitted easily and stays put. Think it's a bit expensive for effectively a short piece of plastic channel with fins but still a lot cheaper than a new door and a carpenter to fit and paint it so overall happy. Will give it the product itself the full thumbs up.

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.

Es muy bueno no entra ni el agua ni los bichos. Desafortunadamente con el uso se le están cayendo las bandas internas. Mira la foto.

Perfect under door seal. Just make sure to measure and cut before installation or it will be a pain.
