Warning: You probably need to spend more
I have owned several houses over decades and never had a 7' door. I was surprised that what I bought was insufficient. Now I have to pay more, wait for the delivery, go without an opener until it arrives, and be irritated just because they didn't make it clear on the box. It is in small print on the bottom of the side near the warnings about potential lead exposure as required by CA.

Huge improvement over my base model Chamberlain opener. Spend time reading the instructions as they’re convoluted in a few areas. Connecting to the internet easier than expected. Adjusting the up and down travel took time because instructions are in fine print. Best to look at YouTube

I recommend instead of buying this extension kit, that you contact a local liftmaster dealer and buy an one piece 8 or 10 foot rail kit. With rail, belt, and trolley it should be less than $100. You have to be prepared to bring the long rail home, but it is much more rigid. I reused the longer rail from my 13 year old Chamberlain, when it was starting to die. Bolted to the new opener just like the old one.

Works great, but overpriced
Installation instructions were short, simple and concise. Just be sure you line up the rail assembly correctly with the larger end circular punch out on top.

This product is needed for a door higher than 7 feet
The rail extension was made of the same quality material as the rail that came with the Chamberlain door opener. It was well packaged and had all necessary parts to install. They even thought of a longer string for the emergency release! The only difficulty I encountered was understanding which sections of the original rail to remove so that after adding the extension the rail was the correct length. But I figured it out and the rest was simple!
