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.

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.

So easy - slides on to bottom of door (Use a hammer to tap it along, into place). It was a little too long - Instructions recommend trimming with saw, but I managed to use a kitchen knife to make a groove, and then I twisted off the extra plastic with a wrench. Just be innovative! Now door closes perfectly and no gap under the door. Once I took off my old door stop piece to replace with this new one, I saw why there was a gap - the old one had all the vinyl flaps worn off. Seems we need to replace every 3 years or so. Worth it for 20$ and so easy! This one has lots of vinyl flaps to keep the cold out.

Altamente recomendado. La pieza llega de un tamaño estándar a lo largo en el que se puede ajustar al tamaño de la puerta donde se desea colocar. Es fácil de cortar a la medida deseada y, una vez colocada en la puerta hace un cierre hermético que no permite el paso del polvo. La instalación en la puerta es superior sencillo.

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.
