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.

Great Simple Repair for Aging Front Door!
Very easy repair, for aging bottom door weatherstrip!! Our old front door was dragging its old rubber weatherstrip, and making shutting and locking the door a real pain! This simple, well made plastic (with metal strengthening inner strip) was such a simple repair! Just a simple hack saw cut, to match the width of the door, and slid it on! That's it!! Now, our door closes easily, and the gap below the door is sealed perfectly!

Quality door seal product
Excellent product. Theses are tough to get on because they grip the door tightly. But they stay put and look good from either side of the door. The "sweep" portion at the bottom adjusts continually to variations in the gap between the floor and the door. So it makes a good seal. Like I said, it takes a little elbow grease to slide these on, but they work great once they ar in place.

Stops drafts
I bought 2. One works great the other one, the bottom pieces ripped off after opening and closing the door for a week. They were easy to install.

Fits perfectly!
Very sturdy but also flexible to fit the bottom of the door. It also does the job as advertised when it comes to noise reduction and weather proofing.

Good seal but breaks after a few months
I've had this on my garage door for about 3 months now and the pieces that seal the bottom are starting to break off. Originally I really liked this item because it was very easy to install and didn't require any screws like our old one. It also seals the door very nicely! Our floor is uneven so we thought the little plastic pieces on the bottom would be a good idea but it seems it seals the bottom so good it's causing them to break off.

Sturdy, Keeps Roaches Out!
This is amazing! It was long enough that it fit our door with a little trimming as needed. Once installed, it completely stopped the air flow coming from under our front door. It's nice and stiff, but not so stiff that it's hard to open the door. We honestly didn't buy this for noise reduction or air flow, we bought it to keep roaches out of our home. It's worked amazingly for that purpose, but it's nice to have the added perks of the noise reduction and draft protection. If I had one bad thing to say about this product, it's a little irrelevant to how the sweep works. In the summer, it was nice and snug on our wooden door when it was swollen, now it's just a tad more loose since the door shrunk from the cold. It's a nice, thick and sturdy door sweep. I would buy it again!

Item as described and keeps draft out

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.

Excellent product! Easy to cut to the length size-was able to do the both double doors and just looks incredible. I may have to order more. Thank you!

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.
