Rated 3.9 out of 5 by 80 reviewers.
Rated 1.0 out of 5.0 by Do not buy this replacement seal I bought this U-shaped replacement seal for my Clopay garage doors. After removing my old seal and cleaning the double track, I found this product fairly easy to slide in the tracks and cut to proper length. In the cool morning sun, it looked like it would work fine, although it seemed loose in the tracks. By lunchtime, it heated up in the south-facing sun and was so soft that it was just barely hanging from one end of the tracks, the rest completely loose and out of the tracks. It is impossible to keep in place, even in this moderate early summer heat (75 degrees), not at all an unusually warm installation location. The product is useless for me, and now I will see if Home Depot cares about customer satisfaction. June 22, 2013
Rated 5.0 out of 5.0 by Good Product Measured our garage. The little t-ends needed to be a certain length to fit in the channels. I watched about five youtube videos. Getting the old stuff out was harder than putting the new stuff in. Just make sure you clean your channels out and make sure there's no bends. (You can correct bends with a screw driver or needlenose pliers.) Then soap up your new insert with a dishwashing detergent/water mix and slide everything in. Ours is the 18 ft garage door, so two people really are needed to slide it in. One to pull, one to feed it in. Leave a little extra on the ends to fold over into the inside to have some if the seal shrinks a little. Overall, it was much easier than I thought it would be. June 9, 2015
Rated 5.0 out of 5.0 by ProSeal garage door bottom seal w/T-ends The seal on the garage door was old, dried out & cracking with several gaps allowing rain and pest in but the ultimate motivation was the snake my wife encountered inside the garage. Before you start this project make sure you have the correct seal that fits your garage door track, if possible carry a three inch long piece of the original seal to compare 'T' track width. DO NOT REMOVE THE WIRE CABLE ON EACH SIDE OF BOTTOM DOOR, THEY ARE ATTACHED TO THE SPRING COIL!! While replacing the bottom seal can be accomplished by one person, an extra set of hands will greatly help. Remove the old seal, clean the 'T' track with a cloth and inspect that the track gap is uniform the full width to the garage door bottom and adjust gaps as needed. I sprayed the 'T' track lightly with silicone spray lubricant and threaded the the replacement seal a foot into the tracks. With one person feeding the seal into the 'T' slot and another gently pulling it along, it can be finished in little time. October 9, 2013
Rated 1.0 out of 5.0 by Follow-up on this product I just wanted to follow up on my earlier unsatisfactory review of this product. First, I am happy to report that the manager of my local Home Depot was exceptionally helpful and provided a full refund for my product. Thanks! Second, a few details about replacement seals that might prove helpful to others: my Clopay garage doors have an aluminum double-track guide to hold the rubber seal, so this U-shaped "T" style seal is the correct type to use. If you have a similar system, you will need to check to see if your door takes a 1/4" or 5/8" width "T" (the part that fits into the track). The reviewed product here is widely advertised on many websites as fitting Clopay doors, but its 1/4" "T" is too loose in the aluminum track, which actually requires a 5/8" T. This accounts for its ease of installation --it slid right in!-- but also for its falling out of the track, a problem very much exacerbated by the softening of the rubber in even moderate sun. So, when you take out your old rubber seal, be sure to measure the width of the "T" part of the seal to make sure you buy the proper sized replacement. June 24, 2013
Rated 4.0 out of 5.0 by Works as advertised, but has a slight flaw This works as advertised. It was fairly easy to install and cheap enough to replace again if it gets torn again. One thing you have to look for is to make sure the seal does not stick out so far that it catches the garage door fram when closing. If the seal presses against the door frame when the door closes, it may get pinched while the door is closing, which will eventually cause the product to fail. To prevent the seal from hitting the garage door frame, flatten the seal while the door is open so it doesn't stick out. This could be held in place by duct tape temporarily, or by using something more permanent, such as a screw with a washer. August 24, 2011
Rated 5.0 out of 5.0 by Perfect Fit Needed bottom to have 1/4" track inserts rather than the 5/16" track inserts that are available in the store. The 5/16" track inserts will not feed in a 1/4" track. This item fit perfectly. And, it's made in the USA!! June 16, 2015
Rated 1.0 out of 5.0 by T-ends too narrow Installation was a horror. The T-ends are too narrow for the 5/16 inch wide tracks, so kept falling off. I finally gave up trying. Could not return to store because I had cut to length. October 25, 2015
Rated 3.0 out of 5.0 by The amazing shrinking seal The seal shrunk about 1" on a 9' door after about 1 month. I now have gaps at the ends. I recommend you leave the seal a little long on initial installation then trim to final length after a couple of months. October 23, 2011
