I’ve been storing my sockets on cheap metal socket rails for, well, forever. Since I bought a roller cabinet and moved the sockets out of their original carry case.
The stack of socket rails was really starting to annoy me. I had about ten of them holding various sockets, deep sockets, impact socket, and hex and torx bits. While they are handy (and cheap) to grab to take over to the job, the rails don’t stand up on their own so I’m always rearranging them in my toolbox to keep them neat.
