Mine's more like how not to do it, I guess.
I like Hansen's but almost half mine don't fit on them. I hate being locked in to a setup. You can see blanks on the gray Hansen for like deep 3/8" 4mm (really) and deep 1/4" 5/8" (does anyone even sell those?) But happily the biggest one in the 3/8" rack is the very useful 20mm instead of 21mm. One day I hope to work a Trabant. Rumored to be the only car on the planet that has a couple of 20mm fasteners. I've added another rail of extractor type sockets and a small set of torque sticks since this picture and had to rearrange a few things to fit them.
I get as much use out of the old metal spring clip rails as the Hansen's. I don't like how they tend to come up when you pull a socket so I pop river them to the drawer. Not a solution I'm terribly happy about.
I liked the Hansen triple trays. Until I realized I really need quad trays, short six point and short 12 point, medium deep, and full deep. The complicate things once or twice I've needed a 12 point deeps too. You can see some 12 points stacked on top of others. The gray rail is front is so crammed I routinely use a pocket magnet to get the short chrome 13mm out, I can't get my fingers in there.
I bought heavy magnet rail and it didn't really help me. I ended up flipping it over a sticking male torx and allen sockets on the sides of it. Upper right of the picture.
Another such magnet rail I used normally for the 1/2" ball swivels. The tend to fall over when the drawer is slammed shut. It *****. I need another spring rail instead I guess. Even more spring rails, my specialty sockets need organizing too. There's a white plastic rail in the foreground with 12 points on it. I hate it. Came from Sears back when I think.
