I’ve had my Craftsman garage door opener for over 20 years, and honestly, I can’t complain, it’s been rock solid. So when the original belt finally gave out, I wasn’t surprised, but I was stuck outside without a way in. Not ideal.I took down the old belt, measured it, and ordered this replacement. When it arrived, I laid it next to the original and was impressed, same track design, same thickness, and it looked like it matched up in quality, too. The only minor difference was it being just a hair shorter than my original. No big deal, I added a link from an old bike chain and had it installed in about 30 minutes.It’s now been two months, and it’s working perfectly. No signs of stretching, and it’s operating just as smoothly as the original ever did. For the price, I’m seriously considering ordering another one just to keep on hand, because let’s be real, these things don’t last forever, and having a spare could save you from being stuck outside like I was.Great value, solid quality, and an easy install. Very happy with the purchase!

Seems well constructed and it is a perfect fit for length and teeth count but it is a little thicker then the original belt, the cap doesn't fit with this belt on. Otherwise it works fine (hope it does at least until i get a new garage door opener to replace my 20 year old one).

Shorter than it should be. No hardware included. Not original. I work with garage doors and I tell you, don’t buy it!

The belt fit great and seemed to be good quality. I bought this belt 2 years ago for my other garage door and it has worked well. So when my other door needed a belt this was my go to. Great value for your money!
