Simple installation

My husband installed this new drive belt because our last one broke. The belt was an exact fit and came with all the hardware needed for installation which he said was easy. I noticed a difference in how much smoother the garage door pulls up and down and it’s noticeably quieter than the last one which is nice because my daughter’s room is right above the garage. Overall I’m really pleased with my purchase.

Perfect Fit for 7ft Door Height Easy Installation

Perfect fit with my 2006 Chamberlain LiftMaster Professional Formula 1 garage door opener. It comes with the necessary hardware to swap the belts. The drive belt is easy to install. The original one lasted 20 years. I re-adjusted the tension accordingly and I had to set the Max Open Limit and the Max Close Limit. It's an exact match with the original belt.

Very pleased

The item appears to be the same quality/durability as the original belt. The size, length, and measurements were accurate according to the description, and the parts fit perfectly upon assembly. There are a few Youtube videos showing how to attach the belt to the garage door opener which helped as well. I am going to purchase another one for my other door.
