The "updated" version changes four things:
Because we moved some of these shelves away from the walls the extra length was handy for a bit of extra support. Our shelves are either back-to-back or side-to-side and we attach them to each other to avoid tipping as much as reasonable. Back-to-back these are pretty solid. We'll upload our printed attachment uh thingie, but we also just use spectra cord (it's what we have excess of) and it's just as good, or better (allows simple movement).
I had two wire shelving units (1" poles) where the leveling feet bolt holes were permanently fastened. I wanted to connect them together to make one pretty-tall shelf unit for my makerspace. Basically I needed to attach something where the leveling feet went to where the top endcaps were, which was unthreaded (see image).
This connector takes a 3/8" bolt (9/16" wrench) to screw into the ex-leveling-foot threads, and extends into the ex-tube-cap hole about an inch, which is more than enough to provide some lateral stability (initial prototype was about 1/2" which was sufficient). The extra length provides a bit of "lift" stability in case... um... not sure.
There's about a 0.05" "rim" to separate the two poles. I don't have a great reason for including that other than to protect the ex-tube-cap pipe so it doesn't rub metal-on-metal with the other pole.
