Rated 4.4 out of 5 by 29 reviewers.
Rated 4.0 out of 5.0 by Does the job of keeping out the weather out These were easy to install. Just use a little lubricant to help the rubber slide through the aluminum rails. The only thing I did not count on was that when water freezes under these the rubber has a tendency to stick to the ice and partially pulls out of the rail. February 11, 2014
Rated 5.0 out of 5.0 by Excellent product! Product arrived ahead of schedule and undamaged; all required parts were included; additionally extra screws were also included;directions were in plain language and easy to follow;The two car garage rails Are shipped in four sections; you will need a metal cutting saw to cut your final piece the remaining width of your door;Rail sections align perfectly, therefore sliding the rubber into the metal tracks does not hit obstacles.if you have not removed A bottom rail and rubber in the past, after sliding off the existing rubber piece use a drill with a bit slightly smaller than the opening of the existing screws.drill slowly and the screws will pop out. Note I said screws because I don't know the proper name of the item that attaches the rail to the door bottom. Removing existing screws is not mandatory, however on the inside of the door your new screws in existing screws will be visible. No damage is done it's simply the appearance there is a tremendous amount of screws holding the rail in place. November 13, 2015
Rated 5.0 out of 5.0 by This Replaced the Original. Excellent quality. Removal of the old weather strip AND aluminum frame made seeing how to install the new set easy. The old weather strip was dried and cracked. I simply cut it away to expose the screws. Once I unscrewed the old frame, I could see how to install the new frame. Unfortunately, you must install the new frame BEFORE you install the rubber seal. (The rubber seal blocks your ability to screw the new frame into the door.) This isn't a negative, its just being mentioned here so you know that in advance. Once the new frame is installed (and you may need to cut the frame to fit your specific door) ALSO make sure you line up each section of frame perfectly - once this is done, then rub some dishwashing soap on the "T" portion of the rubber seal - this will help you SLIDE the rubber seal down the length of the track. I prefer liquid soap - it works the best. Be patient and careful as you slide the rubber seal... you don't want to rip it. (But if you do, you can buy a replacement rubber seal from Home Depot WITHOUT the aluminum track to save you $$). Note: Once rubber seal Is slide into place, on the end, tuck the excess into itself. Leave a little sticking out on the ends - enough to make a good seal at the corners but not long enough to bump and rub the door brackets as it opens and closes. Once install is done, lower your (electric) garage door and make sure it fits. Note: If you have an electric door, and it goes back up when it hits the floor, you may need to adjust the garage door motor. (there's 2 setting dials you can adjust your door with). Sit back and enjoy the new job! (and know that doing this yourself just saved you about $150 installation.) PS. If you are a one person installer, you can use painters tape to tape up the frame as you screw the frame in. July 17, 2015
Rated 5.0 out of 5.0 by A replacement part that actually replaces! Know how you need a replacement something, but your part doesn't quite match the shape of the replacement part? Like when you buy a universal remote that only does some of what your old remote did? Or finding a replacement garage door sealer on a 12 year old garage door? Well, this isn't that. The bottom of my garage door isn't flat. It's bowed in the middle. They don't make the rubber gasket any more. They don't make garage door like that either. But, this replacement has an aluminum piece that fit right over that and only required some longer sheet metal screws to attach. Attached the aluminum support, slid in the rubber gasket and VIOLA! done and done! The rubber even formed to shut the gap in the garage floor of an inch. Still functioning in a Minnesota winter.

Rated 4.0 out of 5.0 by Good looking product Quality product, clear assembly instructions, but screws were short and not suitable for foam insulated doors. October 20, 2015
Rated 5.0 out of 5.0 by does it's job. When installed properly the weather seal will do the job and look good too. Tip: use 1 1/4 stainless steel self tapping screws not the ones including in the kit. March 23, 2015
Rated 5.0 out of 5.0 by Great product! I am very happy with this product. I have combined this with a tsunami seal on my garage floor and now have no more rain water coming underneath. The product comes with four 4.5 foot aluminum mounting brackets and a single 18 foot long vinyl seal. Brackets are easy to drill through and install. Screws are included, although if you have an unusual garage door like mine you may need to buy longer ones. The vinyl seal is a little tricky to slide into place, however spraying the mounting grooves with silicone spray will make this much easier. Overall I have been very happy with this product!
