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.

Answer: 
Hello George - Unfortunately, we don't have a residential opener that has the ability to open 16 ft high. The highest we have is 10 ft. If we can answer any other questions, please feel free to email us at this link, http://chamberlain.custhelp.com/app/ask/session/L2F2LzEvdGltZS8xNDY2NjI5MjIxL3NpZC9JT2xxWklUbQ%3D%3D

Answer: 
Chamberlain openers are only made to work on doors up to 10' tall. For a 16' tall door you need to shop for a commercial style opener. A residential opener won't work for you.

Rated 4.3 out of 5 by 32 reviewers.
Rated 5.0 out of 5.0 by 8 FT. BELT-DRIVE EXTENSION KIT Part was installed professional so my information is limited. Seems to function fine. May 19, 2016
Rated 3.0 out of 5.0 by Decent product This kit to switch from a 7 ft garage door to an 8 ft garage door. It should come with the wider plastic pulley to fit the new wider plastic belt system that replaces the old chain and pulley system. I had to buy them seperatly on Amazon. I wish the company would look at this review and realize I would spwnd a few dollars more to have it work properly. The plastic pulley that comes with the original kit is for a wire that is used to move the door that is not used when you switch to he 8' door system. Using that pulley created slippage and the new belt would come off that pulley. If you follow the directions like k did, it did go together easily (2 hours total time ). I had never done a garage door opener system before and was surprised at the ease. Instructions were decent to follow. Please add the proper plastic pulley to the box for future orders. May 3, 2016
Rated 2.0 out of 5.0 by 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. March 8, 2016
Rated 4.0 out of 5.0 by Chamberlain rail extension kit I was disappointed with Chamberlain because the door opener was not clearly marked as a 7' or 8' door. Had I known it wasn't for an 8' door I would have clearly looked for one that was. As it turned out it was for a 7' door and only in a small space in the instructions did it mention that. It did list a rail extension kit on the accessories page. Now, I'm not a door installation expert so I don't know what a 'rail extension kit' is for. But after calling customer service and speaking with a representative of Chamberlain and her explaining that it is to make my rail fit my door, dummy! She did tell me where it said the size also. Anyway, after installing the rail and opener I got to take it all down, add the kit, throw away the original belt and metal header bar and spring tensioner, then put it back up and it works great. So this is no fault of Home Depot but Chamberlain in my opinion. The kit was an easy install, instructions were clear and it works. I figure the belt was the most expensive part of the kit and I threw away a brand new one as I would have no further use for it. The only reason I would recommend this to someone else is because I'm sure that there are more 'dummies' out there like me. Thank you for your time. February 10, 2016

Rated 3.0 out of 5.0 by 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? February 23, 2016
