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.

This kit had everything needed but the installation directions need to be revised. The included directions for "new installation" were very unclear that BOTH included rail sections were to be used. After reading the instructions multiple times I assembled the rail using only the extended section for the second rail per the instructions. When installing the chain I realized the rail was too short and I needed to use the other included rail also. After disassembling the rail and reassembling it with the longer end rail it was the correct length and everything went fine. The instructions need to clearly state to use both rails for the 10 foot door on a "new" installation!

It appears I will have to replace this rail (make in sections) with a single piece of square tubing to minimize the flex.
