Jin&Bao Universal Garage Door Threshold Seal Strip 20FT Kit, Bottom Waterproof Rubber Weather Stripping Replacement（Yellow, 2 Adhesive）

Some products look like a simple, great idea until you start to install it, and then you find out it's a nightmare and a joke. Not the case for this threshold seal! It's a simple product, the kit is complete, and it's easily installed for anyone with even modest abilities. Once it's done it works in combination with your door's attached bottom seal to provide a positive, airtight, sure seal, even if as in my case, the bottom of the door does not sit perfectly flush to the concrete slab of the garage floor on both sides! As for the installation, all I did was look at the pictures in the Amazon listing and do as shown without even bothering with the instruction sheet. I used a leaf blower and broom to clean the slab off where the seal will go. Then simply unroll the seal and lay it out flat, -then with the garage door open a few feet, set one end of the seal up against the door's roller channel on one side of the door and place the entire threshold in the approximate position it will lay. Now you can just eyeball where it will need to be cut, or you can measure and mark before cutting if you feel it necessary. Cut it to the right length so it fits between the door roller rails on either side of the garage door. Once it's cut to proper length, roll the door down almost all the way so it sets on the seal but you can slide the seal around to "fine tune" where the final position will be. You want the top (highest part of the seal) just inside the door. Now just roll the door down until it's just over the seal. The yellow "safety marking" on top makes a handy visual aid for aligning things so the seal is perfectly straight/parallel to the garage door. With the position of the seal "95% there" I walked outside to double check that the edge of the seal that was visible outside looked straight/parallel to the door out there as well, and repeated the process a couple of times just to make sure that everything looked good from both sides. I then closed the door completely on the seal to ensure everything was fitting snug between the door's bottom seal and the new threshold seal. If you're anal like me, you can walk inside and out multiple times just to be sure that everything is "just so", closing the door and re-adjusting several times. In the end, I found that basically it pretty much just lines itself up when the door is closed and all you gotta do is align the yellow stripe so it's a consistent distance from the door from one side of the door to the other. (Seems to end up with the stripe about 3/16" to a quarter inch from the door). That done, I rolled the door up and grabbed a permanent marker (the only things not included in the kit are a marker and something to cut the seal to length. In fairness, they also didn't include the oxygen I was breathing while I installed it, and I didn't expect them to provide air, so I'm calling it a complete kit!) Then being careful not to move the threshold while marking, just mark on the garage floor along both sides of the seal. Pull the seal away from the lines, run beads of the included sealant in between the lines you made, place the seal back down between the lines, and you're done! For my 16 foot door I only needed about one and a half of the two tubes of silicone included, and even using that much was almost overkill. Two tubes is probably plenty for a 20 foot door. A note about the silicon sealant included and the threshold itself: The sealant is not like silicon caulking. It's a very thick, very sticky SEALANT. I got a little on my hands and was worried about needing gas or paint thinner to clean up but to my surprise it actually washed off with soap and water, but it sure doesn't SEEM like any sort of wimpy water-based stuff! It's really a top quality sealant from what I can tell. The threshold itself is HEAVY, high quality, thick rubber and you aren't going to cut it with the wife's kitchen scissors, so you'll need something heavier duty to cut it than scissors, -which is a plus in my opinion. I cannot say how well it will hold down over time, but I can say that the finished installation seems very durable, and the threshold is heavy enough that I would expect that if or when the sealant might let go, it would be a simple matter of putting down new goop and setting it again. That said, -Depending on how klutzy I or my family are and how many times we kick it when we forget to pick up our feet, I'm guessing that the original sealant will last a good long time! Cons: I can't think of any. Pros: Really nice to buy something this well done. 5 stars. No bull.

It was easy to install, I’m happy that I tried it, had a couple of places where there was a gap after installation, no gaps no snow blowing in and no grass cutting or leaves and most of all no MICE Really easy to install, I’m a 91 year old female and I did it and you can, too.

God product, especially for the price. Easy to install and gives an extra amount of preventing water seepage into my garage. Good deal!

Works great, Easy to use

I put this under my shop doors and it was pretty easy to do. I would suggest letting it lay flat in the sun for a while to get the roll out of it. I had to put weight on one end to keep it down. I would also suggest to start with the doors down so you can line it up correctly. I had to move it around a bit after marking it out and putting the glue down. It wasn't a big deal, but certainly something I'd do differently. I was able to use only one tube of glue, which will allow me to use the other as a spare. I think I went a bit too heavy with the first half and it squeezed out the sides. When I tried to walk/step on the strip to make sure it was all the way down, it slid around a bunch with too much glue under it. I've had it down for a few days now and had to pressure wash/scrub the ship floor. I squeegeed the water out over the strip and it held down well. I guess I'll see how well it holds up over time, but happy with it so far.

Easy to install, works great to keep the out doors nasty outside. follow the directions (recommend having a person to help with laying seal in glue so not to smear) Take your time draw your lines, prep your surface, and get it done. Very durable, Huge value for the money, Fits many sizes up to 20 foot, not very stiff, makes great insulation and durable. Helps Protect from water and wind coming in under the garage door. Highly recommend

I rarely give reviews on Amazon because a lot of what we buy is "meh". Our garage, despite having a French drain in front of it, floods all the time because it sits a the low point of a an extremely steep driveway. We installed this rubber dam and it is like magic...zero water intrusion. Prior, every time it rained we would have to sweep out water. Last night it bucketed down and the garage is dry as a bone. Cheap and effective solution!!!!!

Wowee-wow-wow!! This strip saved us THOUSANDS. Yes, thousands. For the longest time, one side of our garage would accumulate water right in the corner near the garage door. It would pool quite a bit and make for a hazardous trek to the driver side of one of our cars. We inspected for cracks, used a level to check for a dip, and also looked at the actual door. Everthing looked intact. We called out two companies and they, too, couldn't find an obvious reason for the water intrusion. Their suggestion? Crack into the concrete and reset it. $2300. We scoured for some solutions and came upon this stripping. Far less than $2300 and we figured if it didn't keep the rain and snow out of that corner, at least it would keep a tight seal at the base of our garage. "Install" was easy but a bit time-consuming. I would highly recommend 2 people, especially when adhering the strip to the glue. We enrolled the strip, got it into position and then used CHALK to trace it into position. That really helped because we knew where to put the adhesive and it kept the strip straight. The glue was super strong & held the strip in place. And so we waited for the rain... A few days of sprinkles and then a HARD rain. We opened the garage door and found... 🥳A DRY CORNER🥳 Not a single drop of water! Three months later, our strip hasn't budged, cracked, warped, buckled...nada!! Nor has it allowed any precipitation into our garage! This product was money-saving game changer!

(Vivo en 2da planta) El suelo de mi sala estaba al ras del suelo de mi pasillo y cuando llovía el agua que golpeaba la puerta resbalaba por ella y se metía al piso de la sala , así que ya se imaginarán que la sala se llenaba de agua. Con este artículo pude solucionar el problema. Lo coloqué un poco más adentro del límite de la puerta estando cerrada y cuando escurre el agua de la puerta no entra el agua a la sala y toda el agua se queda en el pasillo y el pasillo al final tiene desagüe. Lo mejor de todo es que TRE SILICON , y es muy resistente. Por lo que no tuve que perforar la loza (techo del piso de abajo) para poner táquetes o tornillos para fijarlo. EXCELENTE PRODUCTO, 100% RECOMENDADO.
