It was easy to install and functions but doesn’t extend the opener enough for an 8’ door. More like a 7.5’ door opener.

Please check the manual make sure the opener is installed correctly. The opener by itself should do a 7'6" door so the extension should give you the other 6" needed.

Not sure why the poor review, it is a piece of metal to allow you to extend the opener to open up to a 8' door.

It worked. However, it would have been great if they made this a little longer. When the garage door was fully open, it was getting pretty close to the limit switch on the opener side, even if I add a ~1" wood block b/w the extender and the wall. Without adding the wood block, it would not have provided enough extension.
