Nathan, Some advice from me.

I have some soft plastic tubes on the corners to hold my superglue verticle, so's it won't leak.
I carry a short length of plastic electricial's conduit. I use it as a leg under the top tray when the tool-box is open. It transfers the weight to the tabletop and balances-out the whole tool-box. It also protects the permanent felt pen that I carry.
George, out...........
