Jin&BaoUniversal Garage Door Threshold Seal Strip, Bottom Weather Stripping Replacement Rubber Waterproof 20 FT Length

I got this after the garage door installation person suggested it since there was still a visible gap between the concrete and the door even after cramming pieces of pool noodles into the bottom of the door seal. I measured and calculated that there would be a dip in one spot that could exceed this product's assistance in bringing the height up. I removed the pool noodle pieces and re-measured and came to the same conclusion. I was going to get some self leveling cement fixer stuff (which I should have) but the garage person told me "nah just put the door sealer down and you can always double it up if you need to"Unfortunately I listened to him. I don't believe this product was ever intended to be doubled up for a short segment. To the product's credit, it is easy if you follow the instructions and chalk everything out before you even bring any glue out. You can adjust in and out for dips so long as they don't exceed the height of this product by simple changing where the bottom of your garage door touches when closed. Don't double it up because then there's no way to get that smooth good seal as it comes out of the deepest dip. If you only have dips as tall or shorter than this product, you're going to be really happy with it as is. If you have a gap taller than this product go get some kind of self leveling product intended for concrete outside (so it can handle the temperature swings) and let it completely set up and dry before you bring this product out to try and address other issues.That being said it has significantly decreased how much crap from outside gets in ( it would be zero if I had done the install right). It has withstood all kinds of harsh torment and weather and is still doing well 2yrs later. It was fairly easy to notch out the ends for a great fit against the edges of the opening.I didn't take any stars off since the area where mine was installed correctly preforms as promised.

We just had the first tropical thunderstorm for Southern california and when I heard the weather forecast for it I rushed to buy one of these. The reason being, that our garage constantly gets water leaking underneath the garage door, halfway into the space every time it rains. The previous owner didn't take good care of the garage door trimming or concrete floor seal so I decided to DIY this one myself. I ripped out their old and useless previous stuff. First I purchased the top garage door rubber hose/base trim from Lowes. (Your basic T edge rubber tubing for the metal rail tracking of the door base). I found some tips that if you purchase WD 40 silicon spray lubricant, that it makes it easier for a solo person to easily pull the new rubber across the tracking rail themselves. So I did and it worked great! after the separate top rubber seal install, I then installed this guy for the concrete floor. The tips in the reviews were more than helpful to make sure I was able to (a) do it myself and (b) do it right the first time. Thank you fellow reviewers for your tips!So I first power washed my concrete floor edge so it was free of all gunk and dirt. This of course helps the adhesive I was about to place, actually stick well. Then I cut a piece of this threshold seal strip off that I wasn't going to need and used that shorter piece to measure and mark off sections at a time on my floor, where the trim would soon be laying down. This took a long time but worth it. I used a sharpie to draw lines around the edges of where the rubber seal was going to be placed. Constantly lowering my garage door to test and see if the newly added top tube seal would sit flush with this guy. Then after making my markings, I went ahead and grabbed the full strip this time, aligned it to my sharpie markings and to test before glueing. I again - closed the garage door one more time to make sure my top rubber tracking seal sat flush with this bottom seal strip appropriately and into the curve. I made a few minor adjustments to the rubber placements in certain sections by marking new sharpie lines here or there and then I was finally ready for the permanent glue down. I used the LOCTITE PL 3 X PREMIUM as some reviewers noted. I first put this loctite caulking close to (not on) the edges and then did zig zags in-between those edges. Then I slowly pressed the rubber seal sections one chunk at a time (remember I was doing this all by myself), with the remaining seal waiting to be set next thrown over my shoulder as I pressed sections at a time onto the caulking and making sure I was following my sharpie lines. Luckily you have time with the glue to make adjustments and slide around the rubber slightly before committing to the positioning. After the whole rubber seal was fully laying on the glue and aligned, I slowly walked on it, making sure it didn't accidentally slide around the floor underneath my shoes and making sure it didn't accidentally misalign. After walking on it and readjusting here or there - I put some heavy rocks and bricks on sections of it to keep it weighted as it dried. While I waited for the glue to do its thing, I had some extra Sika Flex caulking left over from my other house projects and put a bit at the edges/end of my garage seal/wood trim where water could get in to prevent water from rolling back in. after about an hour I closed my garage door so the weight of the door could continue the setting process from there. Relieved to report the large rain pour that weekend never got in, the inside floor stayed dry and this worked like a charm! Thank you again reviewers for your excellent tips and tricks.

Made the world of difference in keeping water and extra bugs out of a repurposed garage.

It works great! I have always had some water getting under my garage door and this stopped it. Lay it out in the sun to warm it up and make it softer. Measure your required length (measure twice/three times cut once)😀. Place it down on the floor, lower the garage door to hold it in place, adjust the position as needed, use a pencil to mark the borders on each side of the seal. For a really clean look put masking tape along the border of the seal, you’ll need 2 tubes of adhesive for a standard 2 car garage door, put down the adhesive then spread it out and then put the seal down. Then press it down to seal. Use something to roll over the seal to get it to seal tight to the floor. Bike tire, wheel barrow, something like that and then close the garage door down on it. Adjust the position if needed.

Great threshold seal good quality easy to cut and install with the right construction adhesive durable flexible trim to fit.

Well made and would recommend it

Do not come with glue
