I know there is a name for this kind of tooling, but can't remember what it is called
they work well under the benches, and save bench space for tools that may not be used on a daily basis.
I started building the receivers for the 3 benches, that I will mount them on.

Attaching the mounting plates to the HF 2" receiver tubes, they were cheaper with the 20% off coupon. Then the raw tube at the metal supplier I was using at the time.

Mounted under the bench the end of the tube is flush with the edge of the bench, so when not in use it isn't a snag hazard.
