"...This made it much easier to slide the seal into the aluminum channel...." Read more

Works beautifully! Installation easier on the second door.
I installed this onto two different garage doors—we have a two-car garage with separate single doors.Like other reviewers complained, the rubber came bent, because of the way it is folded around the metal bars in the packaging. I opened it and hung it in my garage for several days thinking that would stretch out those fold marks but that did not work. What did work perfectly was to lay it out on the driveway in the sun while I removed the old weather stripping from the doors. The sun makes the rubber warm and soft and those folds came right out.The channel bar is a little wider than my old wooden garage doors. The instructions say to center the channel on the bottom of the door, but I thought it looked better to have it even with the front of the door and the excess of the width extending into the inside of the garage, so I installed it that way and am happy with it.I used clear packing tape to hold the metal channel onto the bottom of the garage door while I drilled holes. Even though it’s supposedly not necessary to drill holes, I did so because I think it just makes it easier to get the screws in. I attached the first 4.5 foot metal track bar first, then marked and cut the excess off the second one with a hack saw. I installed the second metal channel bar with the factory cut end on the outside of the door and the end that I cut, facing the other bar.When I stood back, I could see some light coming in between my old wooded garage door bottom and the metal track, so I put in a couple of extra screws. It tightened right up and removed those spots with the slight gap.The hardest part was fishing the rubber into the channels because the track for the garage door is in the way. This made that easier:I “fished” the rubber into the channels without shoving it in—I used two hands—one to gently bend the rubber around the door track and I found that it helped to use the other hand to press UP slightly on the bottom of the U shaped rubber to help take the pressure off it hanging in the channel. At the same time I did that, my husband also used two hands to slide the rubber down the channel. He put one finger inside the far end of the U and GENTLY slid it along, at the same time that I “fed” it in from my end. We worked together. We got a little technique going and by the time we got to the second garage door, it was pretty fast to get the whole rubber in. I was glad that we did two single doors instead of one long double door—the additional length of a double door will make the job more difficult. I read some online instructions that said a few drops of dish soap may make the job easier. I though about doing that where the rubber has to slide along the edge of the metal garage door track, but I decided against it because I didn’t want my fingers slippery—I thought it might make holding onto the rubber more difficult.When all done, this is working beautifully. I also installed a rubber threshold onto the garage floor a week earlier. The new floor threshold and this U shaped weather stripping on the bottom of the doors are working together to keep our previously wet garage floor bone dry now. And they look great and fresh.I am very happy with this product.I write honest reviews because I read reviews myself and appreciate how helpful they can be. I hope my review helped you.
