Latest opinions on socket clip/ bars?

I have one toolbox where I bought a few of the hand held strip (I think they were Stanley) with the yellow rubber handle
just the metal strips with the springy metal that goes into the socket
cut of the handle and bolted the strips down to the bottom of the toolbox
I and flip that box upside down and those sockets will not move

basically the same as the rails in post 15, but mounted to the toolbox
