nope
get you some 2" leg angle iron, thinnest that's in the scrap bin
drill holes for the taper shanks in one leg, screw it to the wall
aloris style tool holders can be stuck to the wall similarly with sections of large diameter tube to engage the dovetail and a piece of small angle or whatever for them to sit down on
the 2x4 one is for straight shank boring bars
Tube is a new one I haven't seen before.
Most people use a piece of angle or flat bar that fits in the dovetail. Weld those to a longer piece of angle or bar that's sitting at an angle to make a nice rack. (heh)
This is the one that was on my old lathe that I sold a few months back.
And google just led me down a hole.... I like this modular design - angle tabs bolted to a piece of unistrut so the spacing is adjustable.
Or just two pins spaced at the major dovetail width:
