Jin&Bao Universal Garage Door Threshold Seal 20FT Rubber Strip & 2 Adhesive | Waterproof weather stripping replacement, anti-slip yellow design, -40℉ to 284℉ durable, DIY cuttable, includes 2 adhesives

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.

Stopped the water coming in. Pretty easy install too. Good quality product.

I installed this Universal Garage Door Threshold Seal Strip to help keep water, dirt, and leaves from blowing into my garage, and it’s been a noticeable improvement right away. The material feels thick and durable — not cheap or flimsy like some of the other seals I’ve tried. It has just enough flexibility to conform to the floor while still creating a solid barrier when the garage door is closed. Installation was pretty straightforward. I cleaned the concrete thoroughly first, laid down the adhesive, and positioned the strip. Once it was in place, it stayed put and sealed nicely along the bottom of the door. If you take your time with prep, you shouldn’t have any issues. We’ve already had a couple rainy days, and I can confirm it does exactly what it’s supposed to — no more water creeping into the garage. It also helps keep out small debris and even reduces drafts a bit. A couple quick tips: Make sure your floor is completely clean and dry before installing Dry-fit the strip first to get your placement right Give the adhesive time to fully cure before heavy use Overall, this is a simple upgrade that makes a big difference. Definitely worth it if you’re dealing with water or debris getting under your garage door.

Excellent quality. Installed for months. Seal is high quality. Durable, handles being driven over with heavy EV pickup truck and other vehicles. Perfectly seals bottom of the door. The supplied adhesive was a great surprise. I figured (wrong) would be under spec. It was easy to apply, and has stuck the threshold seal to concrete, without a flaw. Cold or hot weather, rain or shine. Keeps out the critters!

Works as expected. The caulk they sent was black... which I didnt think too much about until it had some oozing out the sides and made a mess of the garage floor. I'm sure its cleanable, but doesn't look very tidy right now. I would suggest clear or gray (since most garage floors are cement)

Title: Transformative Garage Upgrade – A Must-Have! I recently purchased the garage threshold and weatherstripping from Amazon, and I couldn’t be more thrilled with my experience! From the moment I unpacked the items, it was evident that I had made a fantastic choice. First off, the installation process was incredibly straightforward. The clear instructions made it easy to get everything set up quickly, even for someone like me who isn’t particularly handy. The quality of both the threshold and the weatherstripping is outstanding; they feel durable and built to last. The materials used are heavy-duty, giving me confidence that they can withstand the test of time and all weather conditions. Since installation, I’ve noticed a significant difference. My garage feels much more insulated, and the draft that used to come through the gaps has completely vanished. This not only helps with maintaining a consistent temperature but also protects my stored items from dust and moisture. Additionally, the sleek design of the threshold adds a polished look to my garage entrance, enhancing the overall appeal of the space. It’s a small detail that makes a big difference! I also appreciate the value for my money. When I compared prices and quality with other products, this one far outshined the competition. It’s rare to find something that delivers on both cost and performance. Overall, I am highly impressed with this purchase. Whether you’re looking to improve energy efficiency or simply tidy up your garage, I wholeheartedly recommend the garage threshold and weatherstripping. This has been one of the best upgrades I've made to my home, and I’m sure you’ll feel the same! Five stars all the way! 🌟🌟🌟🌟🌟

High quality. Comes with adhesive. Lays perfectly flat when unrolled! Easy to work with. I would definitely recommend and purchase again.

Very easy to install. When it rains hard, water creeps under my garage door. Now it’s sealed. Zero water!

This product has an edge over other similar listings. This is a notch taller, sturdier, but still soft enough rubber. Installed quite easily with the sealant / glue which came along. Water has not seeped under the garage roller door since. Very good quality, years of trouble solved so effectively, thank you kindly.
