We are thinking about replacing the the garage opener, we really like the Model # HD950WF but we are not too sure if we need the extension kit. If so, what size are we to get? Our garage door is 7 feet high, but looking at the current opener, the rail that connects to the opener is like 9 feet long. so how does this work?

thanks for helping out~

Answer: 
The HD950WF has everything that you need for a 7' tall door. The actual rail is long to allow for connection to the wall and the motor and till allow the door to travel the full amount needed.

Answer: 
The extension is used when you have an eight foot door, a standard garage door is seven foot. This end piece is a foot longer than the one that came with the opener, the belt is longer as well.

Answer: 
Hello Confused, and thank you for your question. For a door that is 7 feet high, no additional extension kit is needed. The rail used with an opener designed to fully raise a 7 foot high door will be longer than 7 feet, due to the back and forth range that the "trolley" must travel along that rail - it does not travel all the way to either end. If your door was taller (8 - 10 feet high), then an Read More

Answer: 
Hi Eddie, the 8808CB is the right extension kit for the WD962EV. Unfortunately the image used on the website is incorrect. The 8808CB and WD962EV use a square rail system instead of the T rail image shown.

Answer: 
Sorry to hear that. This extension kit includes a new belt, so you could use it to replace your broken belt. However, you wouldn't need the other parts included in the kit. You could also contact Chamberlain directly, or a third-party garage door installer/vendor to see if you can purchase only the belt.

Rated 5 out of 5 by from Must have for 8 foot high door If you own an 8 foot high garage door you need this for your garage door opener it is a must as long as it is a belt drive it will work for Chamberlain models
Date published: 2016-11-01
Rated 5 out of 5 by from Exactly as described Not much to say. It replaces the end piece of the existing track to accommodate the extra height of the door.

Rated 5 out of 5 by from Chamberlain 8ft Belt-drive Extension Kit This addition to the base opener kit was easy to install and works great. A must have for 8ft doors.

Rated 5 out of 5 by from Perfect! Works great! Installed easily and came with extra parts.
Date published: 2016-11-29
Rated 3 out of 5 by from Does the job Just a box of subs tire parts. I don't understand why you have to pay $45 extra. Why not sell the opener in different lengths?
Date published: 2016-02-23
Rated 5 out of 5 by from Exceeded Expectations Replaced 9 yr old Chamberlain chain drive with new belt drive. Unit shipped early, I installed it by myself using the old Chamberlain mounts, took 1.5 hrs. New unit very easy to program and extremely quiet operation! Extremely pleased with the whole experience. One small complaint - Chamberlain should offer separate 7 ft and 8 ft units. The standard garage door is now 8 ft and forcing customers to purchase the 8 ft extension kit is a total waste of resources (the included 7 ft bar and belt goes into the garbage) Just charge more and offer a standard 8 ft unit.
Date published: 2015-05-12
Rated 2 out of 5 by from Lesson learned The 8 ' extension is multiple pieces attached together. The end result is that it is not rigid and oscillates up & down as the door is traveling (especially when it starts). I had (and still have on my other door) a solid piece aluminum extension; it is completely steady. The motion of the multi-piece extension can't be as good for the opener as the steady one.
