Rated 3.8 out of 5 by 4 reviewers.
Rated 4.0 out of 5.0 by Acceptable replacement Let me start off by reminding potential buyers that there are TWO SIZES for the T-End bulb seals - a 3/8" and 1/4" (referring to the width of the top of the "T" and corresponding to the size of the groove in your door). I wasn't sure which one to buy because when I measured the trapezoidal groove, the shorter side of the trapezoid was 1/4" and the longer was 3/8". I guessed and bought the 1/4"...and it was wrong - doh! The seal kept slipping out of the groove. Thanks to HD's return policy, I was able to return it and ordered the 3/8", which fit much better. Installation was a piece of cake. I removed the aluminum runner from the door so I could work on the ground, then cleaned it with a rag and air compressor. Even at a 60F ambient temperature I was able to work the seal into my 16'-long runner by myself in about 5 minutes. Yes, the seal comes folded many times in the box but it's very pliable and unfolded easily. The only reason this didn't get 5 stars is because I wish the bulb diameter was greater than 1". The old cracked seal I removed was at least a 1.5", probably 2". Still, the new one gets the job done. Since HD's photos for both the 1/4" and 3/8" are identical (grrr...), I'm attaching a photo of a small section of the 3/8". Hopefully this helps someone decided between the two sizes.

Rated 4.0 out of 5.0 by Good product - the key is ordering correct size T-end First, neither major chain in my community sold this product. Home Depot is about 20 miles from my home, so on-line purchasing was a great convenience. I had already removed the trim from the garage door and it made the removal of the old seal and installation of the new much easier. I sprayed the channel with silicone and the seal slide right into place. A little problem with the crease from folding the seal for shipping, but no biggie. I had read one review that stated the seal kept falling out...he probably didn' notice is comes in 2 sizes 1/4 and 3/8 in. I almost missed it. Very old one was flat and hard as a rock.

Rated 3.0 out of 5.0 by Quality The seal was not as firm as I would have preferred and was more difficult to install because of this. December 21, 2014
Rated 4.0 out of 5.0 by Garage door seal Worked well for a 20 year old garage door seal that I could not find locally. Pretty cheap and installed easily. August 19, 2014
