I purchased this product not because I wanted to but I had to. All of the garage door openers available only work on a 7 ft high door where as the standard door here in the South is 8 ft by 10 ft. So, in order to have one work, you must add 30-40% to the price of the opener. So, yes, I had to have the extension which does its intended job correctly. I'm just more bothered by that fact I had to purchase such an expensive extra in order to utilize my original purchase.
Garages built after 1990s are all more than 8 feet. Sears should not sell somethng less than 7 feet and then tax additional $50 to sell a kit. It is like take it or leave it. I would not have bought it had I known earlier that it needed a kit to increase the height from 7 to 8 or to 9 feet. This is NOT fair. There is no disclosure on the box that it does not fit garages more than 7 feet. You will know only when the installer arrives and tells you that he cannot work with it unless you by a kit. He has to make a 2nd trip. Whos is at fault?
You need these to open an 8' door. Expensive for what they are. Should come with the opener. Straight forward install and now my new openers work correctly.
Had to purchase this when installer told us our garage door needed it. Was a little tricky for him to install but it works great.
I have an older Sears chain drive garage door opener and this part does not work for it. The rail section extension that come with this kit is actually 2" shorter than the section it replaces - so there is no way it can make for a longer assembled rail. And the new rail section does not look like what is pictured (does not have the crimped end). I thought the picture indicated there would be two rail pieces in the kit, but there is only one. Not sure what to do now that I have garage door opener removed, disassembled, and laying on garage floor. Aaaaarrghh !
There is another reviewer that stated this kit does nothing. He is correct. Then end piece in this kit is actually shorter than the end piece that came with my stock opener. The chain and cable is 2' approx longer than the one on the stock opener. But the problem is the total length of the rail needs to increase 12" and the piece in the kit shortens length by 2" I cant figure out what this kit would be used for as the chain wouldnt work with the included piece. Its maddening!!!!!!! I will be getting a 10' kit as it hopefully will include a longer section. The picture for this item shows 2 pieces. Only 1 piece is included in kit.
The extension kit was easy to install to the other rails which came with the original opener. Also, the new chain assembly in the kit was easy to install as well.
If you are installing an opener on an 8ft door you need to purchase this item.
It was not as sturdy as I thought it should, it carries a lot of weight opening the garage door. I thought they had made improvements on the newer style but they did not.
