This kit to extend from the standard 7' to 10' does what it says, it replaces two short sections with two long ones but I am not sure it is a good idea. I wish I had researched more to see if there was a different door opener that was made to be 10' because at 10' the bar is very floppy. I have it secured very nicely at both ends but the bar flopps all around while operating. The entire 10' needs to be larger or heavier metal to span this distance. So far, it does work fine.

Rated 2.0 out of 5.0 by AgentSmith 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.

Rated 5.0 out of 5.0 by Gordy 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.

Rated 5.0 out of 5.0 by Gordy 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.

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.

Rated 4.0 out of 5.0 by dressageman 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.
