Liftmaster/Chamberlain/Sentex 41A5434-11A Garage Door Openers

So glad to find this product my aging garage door opener. It is a perfect fit and came with detail steps to install/replace worn out belt. Good quality product and saved me a bunch.

El producto llegó a tiempo y buena calidad

This belt matched my OE belt exactly and has been working perfectly! The install was a bit tricky, but if you watch the YouTube videos on how to install the belt and follow the instructions exactly you will be good to go. I would 100% recommend this replacement belt!

This belt was the perfect replacement for my original one. The YouTube installation videos are good, but I made the mistake of installing the belt at the trolley location after the initial breakage. After installation (disconnecting from the door bracket), I observed the trolley only going halfway -- the auto-up direction safety feature on a door closing. So, I removed the belt and ran both, the up and down cycles fully. You have to watch the gear turn at the motor without the belt on to see this. Counterclockwise is the down cycle; clockwise is the up cycle. Let the trolley move closest to the closed door (close cycle). I surmised that the cycle had not completed before the initial break. After doing that and reinstalling the belt (with the trolley closest to the closed door) it was easy to make the minute up/down adjustments and everything worked fine. In fact, it prompted me to adjust open/close positions on the other two garage openers. Sorry I don't have pictures for this, but I hope this explanation helps. Live and learn!

Perfect fit replacement, appears to have high quality it is manufacturing, was very easy to replace
