XJ Tube Doors (2 Door)XJ Cherokee 2 Door Tube Doors Kit This kit contains 1 1 2 . 083 ERW tubing and a piece of 1 2 x 1 1 2 flat stock to mount the tubes to. The photo above is an ALMOST completed kit that has been welded together and attached to the flat stock steel. The doors in the picture still need to be gusseted to strengthen them. We plan on adding gussets to this kit, as soon as possible, that will weld near the hinge plates on the tubing. Latches can be purchased
