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.

Best weatherstripping I found for bottom of door
Fit front door perfect, doesn’t move and has air tight seal. Great quality weatherstripping. Also easy install and to trim length with light sanding of edge to give finished edge.

Economical Solution for Old Larson Door!
Extremely easy installation! I had a very old Larson storm door which needed 3 seal fins. The MD Clinch seal was cheaper than just one of the seal fins!!! The door was only 1 5/8" thick rather than 1 3/4", so I added a strip of aluminum to act as a shim ... worked great!

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.

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.

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!

Issues installing but so far works
I received it today and just installed it. I dont know if the clear one is a different material than the others but it was horrible to install. 1) I would get a non clear version because it would hide spaces, gaps, blemishes, and future dirt and bugs. The clear doesnt give it a clean look. 2) measure and cut before install. I ordered a 36inch for a 36 inch door. Make sure the side facing the doorframe/outside doesnt have a lip. If it does you will need to cut a notch for that lip so the door will close. 3) Do a little at a time. As you push the plastic, check the edge is fully on both sides of the door before pushing more. First attempt, the other end came off the door. Second attempt I had to use a putty knife on the side it came off of and a hammer with towel on the opposite side to get it back on the door. At this point the strip was on the door and would not budge to even come off the door to try again. 4) when the strip was on half way it would not go further. I had to use a block of wood on top of a towel and hammer it the rest of the way. The instructions do say to use a mallet and block of wood if it gets stuck. 5) if you have finishing molding for your flooring by the door be careful - it pulled my quarter round right off. 6) That strip the water coming off the door is supposed to glide over and go away from the house - it gets pushed in towards the house and gets stuck that way when closing the door. 7) I just installed it so dont know if opening and closing the door will get better. I have to use my body and force it. For now the molding is to the side. I am going to wait and see how using the door goes for a few days. Then see if I need it tweaked. Today is an extremely windy day and I feel no air coming through the door anymore. But it may be too tight. It was not a quick nor easy install. With a cream inside paint and maroon outside paint I thought clear would look better. Now I believe something opaque would look more finished.

Works but didn’t install easy
Not as easy to install as advertised. My door is 1 3/4” so it should just slide on, but it wouldn’t, I had to use a mallet and WD40 to get it to slide on. The outside snapped into place, but the inside would not, leaving a small gap. It could be that after 20 years, the very bottom of the door may have swollen a bit. It works though.

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.
