Works great on doors taller than 8 feet
If your garage door is 7 ft the original rails will work. If your door is 8 ft then order the 8 ft rail extension kit. If your door is taller than 8 ft up to 10 ft this kit will work. My door is 8 ft 10 inches tall and the 7710Cb-P / 7710Cb rail extension kit installed and worked perfect. The rails included in this kit fit with no issues. I did remove 2 links from the chain in order to properly adjust the chain tension. Simple enough. Works great.

Works as advertised
Quiet operation, Very easy to install, perfect fit. Great quality. My garage door opener fit up to a 7' door, my door is 10'. I installed this extension kit and it works perfectly.

Extended my 8’ garage door opener for my 10’ Door!
Very easy to install. Came with two extensions and chain. Directions were easy to follow. Everything works great.

Worked great.
Gotta have this if you have a tall garage door, read the door opener instructions and know your garage did dimensions.

Great product, s***ty instructions!
Unit worked fine, instructions left a great deal to be desired. The ten foot extension extended the shaft to over 13 feet. No mention of that in the instruction sheet. The original ten foot T bar on the lift master was ten feet long. All of the wires had to be extended and the mounting brackets moved.

Works as should
A must have tool for changing springs on over head doors.

Bad, just bad.
This thing flexes 4” when the door closes even when properly adjusted. Bad quality to match the Chamberlain opener.

bonne qualité, moins que l'original, mais 20 ans plus tard, la qualité est diminuée partout...
