Rated 5.0 out of 5.0 by Carguy easy change over.
For those who want to extend the travel of their 7 foot door opener to accommodate an 8 foot door and it's travel this is a very easy modification to do. Instructions were very clear and it the kit had everything needed to do the change over.

Rated 5.0 out of 5.0 by Lov231 Chamberlain 8 foot garage door opener
This unit replaced a Genie which was purchased 5 years ago and I had nothing but trouble with. Unit went up quickly since I was just replacing the unit and programmed even easier than the Genie it replaced. The cost was way cheaper than the Genie and was able to purchase a second unit for a little more than the original unit. I would highly recommend this unit.

Rated 3.0 out of 5.0 by kjs356 Not the correct extension
All of the components were included with this extension kit but the chain was too long and the hole in the rail for the pulley was too big. I had to shorten the chain and make a bushing for the bolt to fit the larger hole. The box was labeled correctly but the parts seemed to be for a larger garage door. I made it work but it took a lot of time and effort. I have to install another one of these but I plan to check the parts before I start the installation this time and if they are not correct I will return it to the store.

Easy to assemble and install. Makes a nice difference to be able to open the garage door the entire 8 feet. Grade of steel not quite as high as the one I replaced on my 20 year old Craftman opener, but still gets the job done.

Rated 3.0 out of 5.0 by Homeowner Don't forget the rail extension!
I purchased a Chamberlain garage door opener in store, failed to notice the fine print that an extension is required for doors taller than 7ft. Unfortunately they don't stock this particular extension in the store so I had to order online. The part worked fine, what I didn't like is that it simply replaced the entire chain assembly and one of the rail connection pieces, so two processed/manufactured items are now waste and only good for scrap metal. Not an environmentally concerned packaging system, adding to the chain link instead of totally replacing it would have been a more environmentally friendly option. Otherwise, does exactly what it needs to do.
