It looks weird with the handle folded into the storage position. In operating position, it’s much like a sliding Tee handle. The mechanism is more slender than most traditional 1/2dr ratchet adapters.
Sorry about the extension. I moved my stuff around a few weeks ago, and don’t know where I have a shorter 1/2sq drive stud right now.
Mine seems to be missing the spring that puts tension on the crossbar, covered by the 1916 patent. I guess it broke off, but I don!t really see where.
