M-D Building Products 43336 Vinyl Cinch® U-Shape Slide-On Under Door Seal, Easy-to-Install, Energy-Saving, Weatherproof Seal for Doors, Effective Draft Blocker, Ideal for Home (36 Inch, White)

This is a good product at a great price. The dimensions in description are accurate. It’s a bit tough to install but I pushed it onto the door with my heel (with shoe on of course) and it was easier than using my hands. The last bit I used a rubber mallet to get it fully onto the door bottom. It looks clean. Quality is good. And it keeps dust and water away from hallway.

This under-door seal was super easy to install and fit securely under my door. It looks great and keeps out drafts, noise, and even those annoying little bugs that used to sneak in under the door. The difference in temperature in the room is already noticeable, especially on warmer days. Plus, for the price, it’s an amazing value! Highly recommend it if you’re looking to seal up any gaps and improve comfort at home.

The box was severely damaged in transit and the seal was slightly bent but because it was needed ASAP we didn't request a return. It was easy to install and seems to be working fine.

Purchased this because the builder grade one was breaking apart. This was super easy to install and the color is perfect to match the door. It protects from any bugs or insects from crawling in. It is adhered properly and will not slide or fall off. The quality is great and does not allow water or bugs which was my main concern. Highly recommend when looking to replace!

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.)

So far so good. Slid on and seems like a tight fit. Was getting tired of bugs crawling in and am hoping this will do the trick

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.

Didn't fit my door, despite measuring, but I see what the issue was. Our door is just too low for the bottom part. When I tried to send them back, apparently, it was cheaper for me to keep it, so they gave me my money back. I don't know what I'm going to do with it, but I was pleased about the service - as usual. It's a shame because it seems the product is of high quality and really would have done a great job in protecting from drafts. I had to completely rethink what I needed for this door. It slid on firmly when I tried to install, but it was just too long.
