Does your extension kit fit with the older Craftsman upside down T-rail system?

Asked by: NesnaNilra72
I don't believe that it would. The rail extensions included in this kit are square tubing.

Chain Drive Rail Extension Kit is simple to install and works perfectly extending my Chamberlain Opener Rail to work with my 10 ft. door. Everything needed to extend the rail is included in the kit. Hardware still used in the assembly that are from the opener's set of hardware fit the extension rails perfectly. Once assembled the completed opener does not look modified in any way and works perfectly. I can't believe how easily it all fit together.

Rated 2 out of 5 by from 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 3 out of 5 by from floppy 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.
