06-41B4103 tensioner [041B4103]

I had to replace the entire belt drive because of insufficent tension when installed in accordance with instructions. My doors are extremely heavy. Installing by the instruction allowed the belt to slap loosely when raising and lowering. I learned to tighten several additional turns to just remove most of this slack.

You had exactly the part I needed to repair my garage door opener, the belt tensioner which must have shot somewhere deep into my messy garage. The replacement part came overnight allowing me to delay cleaning the garage a while longer, Thanks a bunch!

Part arrived within the given time frame!
