These are my custom tube doors I built for my Jeep Grand Cherokee ZJ. The material is square tubing from some old industrial carts I picked up. They already had a few hinges on them that I reworked to use for the doors in the factory hinge locations and there were already a couple 90 degree bends in the square tubing from some pieces of the cage, I was able to tweak the bends a bit and make them fit my door frames. Then welded them up, added some cross braces and gussets in the bottom corner of each for added support and a finishing touch. I used gate latches to lock the doors in place. Simple yet effective design. I’ve received a lot of compliments on these and I’m very happy with how they turned out. They’re a lot of fun to drive and wheel with.
