Rated 4.7 out of 5 by 6 reviewers.
Rated 5 out of 5 by Screw drive extension Good product. I just think it should be part of the purchase. Just because my garage door is 6 in. taller I shouldn't have to pay extra money for an extra 12" of rail. June 29, 2010
Rated 4 out of 5 by Great price for the item, Easy instructions. I had one problem with my installation process. The opener was for a 7 foot door. It said on the box that I would need a extension kit for the eight. So I bought the kit they had at the store. It turned out, wrong kit. Had to order the right kit online. It took a few days, but the store was easy to work with and it was easy to order online. The intallations instructions were great and the parts bags were colored to help with the process. Wouldn't recommend for someone to install without some kind of training and understanding of framing or carpentry background or working with tools. November 2, 2011
Rated 5 out of 5 by Did not fit my unit. The screw drive on mine was not adaptable to an extension. December 28, 2011
