Rated 4.4 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Headroom Conversion Kit installation Everything was pre drilled, matched perfect. Instructions were simple and easy to follow. When finished, door worked great, was quiet and gave me the headroom I needed for the doors. June 9, 2015
Rated 4.0 out of 5.0 by works well for the low headroom garage once you read the instruction a few times, the installation became pretty easy, the harder part is to drill a few holes on the track and cut off about 6 inches of the track to match the length of the lower door track. Wish the kit includes a few more track bolts. Between the track that came with the door and the low headroom conversion kit, I ran out of track bolts. I bought two sets of this kit and they both worked very nicely. The only problem I had with this kit is the location of the Bent out Flange where you supposedly hooking the S-Hook onto is not placed in the correct position, had to move the S-hook behind the stationary sheave so the sheave attached to the spring does not hit the 3-hole-clip when the garage door is on its way down.

Rated 5.0 out of 5.0 by Great DVD and easy to install All smiles, easy to install, nice looking, works great December 18, 2012
Rated 5.0 out of 5.0 by Much better than the "quick turn" kit I installed previously. Well made product. I replaced the short track kit I installed originally with the door. The only problem I encountered was the instructions did not tell you that the kit is for an 8 foot door. You have to cut a foot off the track for a 7 foot installation July 28, 2015
Rated 5.0 out of 5.0 by Product worked like a charm. Low hr kit saved us a lot of extra work. It also made it possible to install a garage door opener. Sweet. June 11, 2013
Rated 4.0 out of 5.0 by just what was needed very easy to install, doors worked fine without kit but auto opener would bind and reverse. bought 3 doors but only use one with auto opener. this took care of problems and am very pleased July 28, 2015
Rated 5.0 out of 5.0 by What I Needed Everything you need if you have clearance issues. Just call Clopay if you have questions very helpful. HD clerk was untrained on how to order however. April 14, 2015
Rated 4.0 out of 5.0 by Best conversion Kit for Low overheads. It was a great product for me as I was converting a carport into a garage, it enabled me to use it in areas where I had low head room. Everything in the kit was as promised and it made a great difference in the rest of my project. I would recommend it for all low ceiling projects. July 1, 2014
