Okie doke. I've been searching the net using google looking for some extruded aluminum stock in a very simple profile. So simple I can't find anything quite like it.

I'm hoping someone here has experience in any relevant industry to give me some pointers. I'm looking for something that's a close match to the image attachment (close to 3" would be nice). More details can also be found at the following link: http://www.t-linespeakers.org/oddsends/box/

I've already written to the author of the page. What he didn't mention on the page is that the diagram is based off a real enclosure that he did not construct himself. Argh.

Any help appreciated. Even for other extruded profiles that might suit building something like the linked diagram. I know some aluminum ladders use wide u-channel extrusions. See my case/chassis/enclosure thread to find out what I need this stuff for.
