Questions & Answers

Will this work on a 9' door?

Asked by: beel
Yes. The opener has an adjustment feature that allows for doors that are not exactly 10' long. I installed one on a 9'-9" door the other day.

Asked by: jam
I'm currently using the 10' rail extension kit. It works. However, if you can find a 'one piece rail' for your unit I'd highly suggest it. When you extend that sectional rail out to 10' of length it gets pretty darn flimsy. I'm not impressed and not sure how it's gonna hold up? I'm currently inquiring to see if item # 2770CB is compatiable with my unit. I wish I'd known about this before.

My garage door is 10'6"s. Will the 10 foot extension kit work for this application?

Asked by: Rambo
Yes it will work for doors up to 10' 6" tall. That is the max height.

My door is 8'6" will the 8 foot kit work or do I need the ten foot kit

Asked by: Takenforaride
8' 6"'s is the max adjustment on this rail kit. You will be fine with the 8' kit.

10 ft. Belt Drive Rail Extension Kit is rated 4.3 out of 5 by 6.
Rated 2 out of 5 by from Did not enclude any type of direction as to what... Did not enclude any type of direction as to what to do with the parts that were in the box. The directions that were provided with the door opener were not clear either. I ended up having to go back and take the rail apart because it was not clear which side of the trolley bar to put the opener on!

Rated 4 out of 5 by from Worked like a charm I have a slightly larger than normal garage door, so I bought the 3/4 horse Chamerlain Garage door opener and then realized that with my 9 foot door that I needed an extension kit. Bought this belt drive extension and came in the mail within 7 days. Im not a amazing handyman but this was very easy to install. Reason why I rated as a 4 out of 5 stars was because the price for the kit is too high. when you pay $250 for a garage door opener and then have to spend another $120 for an extension kit, seems like a money grab. other than that, good to go and works great.
