Included all the alternate parts to use my opener with an 8 ft door.

Extension kit arrived 2 days before the estimate! As I already had the opener assembled, it only took a few minutes to add the extension & new, longer belt. Works as advertised!

Extension allowed me to go directly behind the beam in my garage ceiling. A 4” hole was cut in the beam previously which fit the opener carriage tube perfectly. Very happy Much quieter than my last opener

Easy replacement for the rail and belt. Had the new opener up and in place within 15 to 20 minutes. Shipping was fast and it arrived a day earlier than planned.

Just what I needed to extend the opener to work on an 8 foot door. The tracks could be secured together better, though. It's just a slip fit, and requires tension from the belt to hold it all together.

Seems like a racket. Sell a opener for 200, and then need to buy an extension kit for another 50. Why not sell it together or be more helpful in knowing the price of the opener is only the beginning

The package that the customer bought only says that it's for 7-ft door in one small three-quarter inch square on the packaging. I had the entire thing installed before realizing that I needed a longer section. You might want to put that in your instructions and label it better on your box because this is ridiculous.

I think it is irresponsible to have to buy an extension kit after buying the garage door and having it ready to install and then see in the fine print that it is needed for an 8ft door. Then have to wait four days for the kit to arrive because no diy store carries it.

We added this extension kit to the Genie garage door opener we purchased, to accommodate our 8 ft garage door. The door would not open smoothly. This extension set is cheaply made and not strong at all.

The items were as ordered but one of the rails had the hole drilled wrong. Caused problems installing to where I had to order another replacement part. Then they sent parts to wrong address after they sent original openers to the right address.
