    • Complete kit. Exactly what I was looking for!
This unit is compatible with the Craftsman line of belt driven garage door openers. I believe that the craftsman units are rebranded versions of the Chamberlain's. Specific for my application, the rail extension, belt attachments and wire extensions were all interchangeable. Despite the sparse product description, the extension kit was very complete and included everything I needed to extend the original 7' Craftsman. From memory, the kit included the following: - Extended belt - Rail extensions - Directions/instructions - Belt attachment/hookup hardware - Wire extensions for the door sensors I installed a standard height opener at the same time as this extension kit. The installation was a straightforward process. The opener had enough adjustability to easily compensate for the added length. I was able to follow the instructions that came with the standard kit to set the full open point, full close point and closing force without any issues. I would recommend this product. Despite the marketing material and product description being sparse, the kit was very complete and fit my needs. This allowed me to update my opener without going to an expensive custom solution. ... show more

    • Kinda poopy to have to buy this
Like all others, the normal doors are 8 foot. So the extensions should come standard. Works great and easy to install, can be done by one self too.

    • Great Product.
Used this on a chamberlain garage door opener to install on a 10’ tall door. Worked perfectly for what I needed.

    • Worked great
Instructions were fairly clear. Make sure you understand everything before snapping rails together. Once assembled, it will not come apart. This came with almost everything needed. The only thing I had to buy was additional wire and wire staples, which are needed for tall garage door opener installs. This kit works like a charm. ... show more

    • I love the new belt drive vs
This is exactly what is says it is. But...here's what I learned; I have a 9-foot plus door and figured I would need a 10-foot extension to match, but since I only open the door 8 feet (and my old opener was set to open that far), the 10-foot extension was too long. After a day of figuring this out and trying to ask the right question of the Chamberlain customer support, I finally ordered the 8-foot extension and everything fell into place. I was able to use some of the existing mounting hardware (from the Genie that I was replacing). Once the track and opener are mounted and all the electrical connections complete, the first step is to set the open and close limits, and I found that with the 8-foot track, I still had a few inches to spare. Amazon accepted the return of the 10-foot extension with no questions asked. Bottom line, I ordered the track that matched how far I wanted the door to open, not the rough measurement of the door. I love the new belt drive vs. my old chain drive and it is as quiet and beautiful as everyone says! ... show more
