Wanted to get my computer off the ground. Attached these to a shelf and had space underneath for a UPS and 4 drive bay.

Very solid even with 75lbs of load on top!

Needs 3/8-16 coupling nut https://www.homedepot.com/p/Everbilt-3-8-in-16-TPI-Zinc-Rod-Coupling-Nuts-822281/204337391 and a standard shelf 3/8-16 leveling foot. (mine came from shelfs I had converted to casters, but should be easy to find)

Hammer the nut in and use #10 X ¾ screws for ½ shelf. predrill the holes.
