Here's an easy to make custom grab bar I whooped up. It is made out of common schedule40 steel pipe. The upper part is 3/8 and the mount portion is 1/2in.
You can make one any size you needed, and it requires very little welding (one 3/8in pipe is cut in half to facilitate screwing everything together to form the rack portion). Two sections of 1/2in are selected and one end of easch is pounded flat where they bolt to the frame. This can actually be done without heat if needed. Attach these and place the rack on in position and weld it in place. Of course, you can add expanded metal ot a piece of plywood as needed.
