So you've found that a rack that uses threaded rods has space to fit in a shelf to hold another piece of equipment on it, but to get a shelf to fit that spot....you'd have to take the whole shelf apart, thread on bolts and put it all together again. An applications engineer contacted me to find a solution....and I did. It's called a "slip-on lock nut"(http://sliponlocknut.com/). It's actually two nuts...one on top of the other.
It works like this:
You'd line up the slots in both nuts by turning them, then fit to rod and turn them to close on the threaded rod. This way you don't have to take the rack apart. Just put four of these on to the four threaded rods, if that's what the rack uses, and put your shelf down on it to put your equipment on it. It's that simple...well, except for making sure all the nuts are in the right place so the shelf will be level.
