At the Northern tool link, the TBX2502X is 26 1/2 x 12 x 9 5/8.
At Amazon in the THIS ITEM chart, the
TB2502X is 16 x 29 x 13 in.
That's not just juxtaposition or rounding error. I would want to know what it REALLY is before ordering.
Hmmm... further down, it's 26.5 L x 12 D x 9.6 H-Inch.
Personally I'm not a fan of 12" boxes for rolling cabinets (cabinet, middle or top). I had an intermediate depth (16" I think) Middle for a while, with a 12" Top Box, and it was just OK. I replaced the Mid and Top with a full depth top box with more drawers than the old Middle+Top, and that is awesome. Takes up the same amount of floor space, too.
I only find 12" deep boxes useful for portable use, or on top of a workbench, because they don't take up as much space. But I've been trying to move all of them off of workbenches (even though I have a 10' workbench), because... they don't belong there, and they take up space. A workbench is for work, not storage.
Sorry, got off on a rant there.
