MD Building Cinch® U-Shape Slide-On Under Door Seal, Brown, 36in

I’m very pleased with this door sweep. I removed the old one, cleaned the bottom of the door, measured everything according to the instructions, and cut the new sweep to length with a hacksaw. It cut very easily. The fit was quite tight, which I consider a good thing. It took a fair amount of pounding with a hammer and a block of wood to slide it completely across the door. After installing it, I used a screwdriver at an angle for leverage to push the sweep snugly against the bottom of the door along its entire length. Once I did that, the door closed properly and the seal was excellent. I positioned the slightly rougher cut end on the hinge side, where it’s hidden. I could have smoothed it with sandpaper, but since nobody will ever see it, I didn’t bother. Overall, this was straightforward to install, feels secure, and provides a nice, tight seal. It works exactly as I hoped. We’ll see how it holds up over time, but my first impression is very positive.

This was exactly as expected. The front door of our home had a metal U-shaped guard with a rubber seal that finally broke down after over 22 years of use. I could not locate a replacement rubber seal to replace the one previously used on the bottom of the door, but did locate this product and took a chance. At first, the seal was difficult to slide onto the bottom of the door. Once we lightly coated the inside of the U with silicone grease, the seal slid on nicely with a little help from a screwdriver to get it over the snags on the door. It fits the door perfectly and actually looks better on the bottom of the door than the previous set up. It is the right thickness for the bottom of our door, does not impair the door from opening or closing, fills the gap under the door that was highly visable from the inside of the home with the light hitting the door and seems to be of excellent quality. The previous seal had 6 screws attaching it to the door from the outside. We predrilled 3 holes through this seal and attached it will three of the original screws to ensure stability over time. We did need to trim less than 1/2 inch of material off of one end to replace the previous seal, but that was easy enough to do with a hack saw. Overall, we are very happy with this replacement part and look forward to many years of use from it.

My expectations weren't very high for a cheap sweep but I was rather pleased with what I got and the results. The material (vinyl) in the photos make the thing looks somewhat hard/dry/plastic-y so I was somewhat uncertain how well it would work, but it's actually nicely balanced. The walls of the sweep that adhere to the door are thicker and more rigid to create a very tight grip while the fins are thinner and bend more easily, vinyl soft and durable to create a good seal. One side of my door has a 1/2" gap and the hinge side has a much much narrower gap but it adjusts on both sides perfectly well to create a perfect seal. There is zero light leaking in from outside now. If you have a standard 1 3/4" door this thing definitely installs without adhesive or screws and can maintain grip. This might have to do with what surface your door has - mine has a coat of latex paint. In fact, the thing is so tight that installation is much easier with a rubber mallet. Sliding it in manually is probably going to be an effort so be aware. Aside from that, installation is a breeze. Measure twice, cut once. Also, once you actually install the thing, you might run into some minor issues with the door not closing if you for example, push the sweep a tad too deep and it bumps into the hinge. Recommend having a utility knife or clippers to do some fine trimming at the ends and this can clean up these sorts of issues. Glad I went with this product.

Perfect fit and looks great! Easy to cut to size and install. The description was accurate and it seems really well made. Took me under 5 minutes to install, including clean-up. I made sure our door was the correct thickness and had at least 0.5" (~13mm) clearance. It is a tight pressure fit on the door and hasn't shifted at all. It makes a better draft and water seal than our old threshold gasket did. Time will tell on how it wears, but so far, I'm very happy with it.

Easy to trim with a fine tooth hand saw. Fit perfectly, I hammered it on with a rubber mallet. Thought two!

After wanting to change out my existing door sweep for the door to my garage for years and looking at literally dozens of them, I settled on this one. Glad I did. Door is 32" x 1 3/4". I used tin snips to cut the additional 4" off, but I did it in pieces so I wouldn't ruin it. (Might've tried the hacksaw route but mine had rust on it and that wouldn't look good on white!) Easily slid on with Windex (like another reviewer suggested). You can push it more than halfway, then hold a 1" paperback book flat on the end and gently tap with a hammer the rest of the way. Because of the shape of my door, the edges on the ends poked up and it was hard to get the tin snip on them. Do prior to install (or probably could use fingernail clippers afterward). I had a 1/2" gap to fill and this fit perfectly. After opening and closing the door several times already, I'm confident it will stay on. My original one was black on a white door - the previous owners had painted it white and it was just ugly. Love this one thus far. (Tried to include a pic but couldn't get it to load.)

I bought and installed two. Then discovered I could use one with Kerf rail attachment so ordered those as back up. For these U channel type one came in fine shape. Other was deformed with the four seal ribbons bent almost to 80°. But I was OK with that because one door had a very small gap to seal, so fit the deformity. They install hard even using trick of soapy water. If you can install from bottom up do so and not hammer much sideways. There is a rubbery seal on the outside along very top of U channel that is delicate and easily damaged. But I see it is useful to keep water out which would corrode metal doors. Trapped water is such a concern that I would not install these on doors not completely out of the rainfall. One is working fine after a month. The one on the tight threshold tore a seal fin off within a few weeks. But still three were working. I needed to temporarily seal an inside door with wide gap. So I stole this failing one to do that. Worked great as looser fit and adjustable height. The U channel had damaged the metal door paint badly. Now I believe the previous owner repainted the door and probably with not the best paint. But it is something to consider and all the more reason to install very very carefully. Product has its place but would not use on a tight fit again.

Keeps out noise and pests. Awesome purchase to replace my existing piece that left a large gap. Very easy to install, just cut to length and slide on.

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.
