Answer: 
The 10' extension will work fine with your 9-foot door. You will simply adjust the travel length to accomodate it. The installation is the same, only the final travel adjustments. Adjusting travel is a very simple and straight-forward. You will find it to be a good product. Make sure it is compatable with the rail you have if you have an existing opener.

Answer: 
Hi LWAK! To ensure you can open your garage door to the full open position using the 10 foot extension kit is the best option. You are correct that your garage door opener will be mounted back further due to the extended length of the rail. Ensuring that you can raise your door to the full open position greatly reduces the chances of unintended contact with the door when entering or leaving your garage.

Hi Lee! This item does not appear to be able to be set for store pick up. However you can choose to have it sent directly to your home. According to the Home Depot website this item would qualify for free shipping as well!

Answer: 
Rail extension that lengthens the standard rail to 10'. New chain and cable to accomodate the extra rail length. 1 piece of lightweight angle iron to reinforce garage door opener hanger (this is really useless in my opinion). All hardware to put it together.

Rated 4.2 out of 5 by 17 reviewers.
Rated 2.0 out of 5.0 by NOT a drop-in fit with low-end chain drive This 10' extension kit is described as fitting all Chamberlain chain drive openers, but it did not correctly fit the PD220. The chain is too long,, and must be shortened. This is not a difficult fix and beats dealing with a chain that is too short. The second problem is with the pulley hole drilled in the front section of guide rail. Instead of being a 5/16 through hole like the PD220 section it replaces, the hole is 1/2 diameter on the top. This will not properly support the pulley for the chain/cable assembly. A 1/2 OD x 5/16 ID x 1/2 long bushing must be fabricated. Should have been supplied by Chamberlain. Another example of Design Engineering never actually using the product they designed. August 16, 2016
Rated 5.0 out of 5.0 by Chamberlin 10 ft rail extention Worked perfectly for my 9ft garage door. Instructions could have been more clear. May 3, 2016
Rated 5.0 out of 5.0 by Love the ease of installation with the extension kit This is the second one I have purchased and I love the ease of installation, especially with the extension kit. It also has performed to my expectations. March 4, 2014
Rated 5.0 out of 5.0 by Love the price of this garage door opener. I put this opener up in about 2 hours. It is priced right as always from Home Depot. They didn't have the extension kit, but they ordered it right from the store and it was delivered to my home with no shipping charges. It also shipped very quickly. It came with all the parts and went together very smooth. The performance is very quiet and I love it. April 16, 2013
Rated 1.0 out of 5.0 by cheap product the remotes could not be programmed to operate the door! of course the door is already installed before you know that! January 19, 2016
Rated 5.0 out of 5.0 by Piece of cake Worked just like they described. I ordered it online with standard freight of up to a week delivery. I had it within 3 days. Easy to install. September 15, 2015
Rated 4.0 out of 5.0 by Good rail extension that functions as needed and is easy to install Rail extension for a standard Chamberlain chain drive opener that allows it to be used on a taller door. Rail and longer chain is supplied with this kit. Easy to add length to existing rail. Have to throw out the shorter standard chain which is wasteful, but the kit works well and is easy to install. Should include more bell wire and additional hanger angle iron. You'll have to buy more of each of these to install this kit to make a functioning system. That will nearly double the cost of this kit so expect to pay additional money to get the opener installed and functioning for a taller door. Be sure to recycle standard chain and unused rail pieces. March 5, 2014
