The magnetic one I recommended isn't what you think.
You screw it to whatever toolbox or roll cart you want it on... and it holds tools magnetically. Looks like this, and the magnet is VERY powerful:
I like 'em because they give you a lot more flexibility when it comes to tool arrangement. If I'm replacing the swaybar bushings on a pre-'04 S40, for example, it goes like this:
I stick a 10,13,17,18, and 21mm wrench to it in order on the left half, a 10mm socket on a 1/4" flex-head ratchet in the middle... toss my prybar and airtools on top of the cart, and then stick a deep-well 14,15,and 17mm socket to it, along with a 1/2" impact swivel on a 6" extension - lined up on the right half of the magnetic bar.
Book time on that job is 4 hours. If I line my tools up in order, and put them back in order whenever I switch so I don't have 'em just rolling around in the top of the cart... I can get it done in 1.5 - 1.75 hours.
That's how we make good money. You get organized, and you know the size of every fastener and in what order they must be taken loose. Having everything you need under the car with you so you never have to go back to your rollaway makes you fast, even if you're not working swiftly.
Try doing that with a little rack that carries 12 wreches in order. Several of the guys here have carts loaded down with several complete sets of wrenches.. wobble, straight, and deepwell sockets... their airtools... etc. It makes the thing heavy (I usually roll my nearly-empty plastic
Matco MTSC2 cart around with 1 arm) and there's too much stuff there. I like having what I need and ONLY what I need for the current job on my cart.
To each his own.
