SF Bay Area source for Telestrut (telescoping metal framing)

[BRCFS]

Hi All,

I am working on an art project that I need some metal framing. I don't really have access to a metal shop or welding so I was thinking of using some telescoping metal framing. The best option seems to be Telestrut (http://www.unistrutohio.com/telestrut-t ... ubing.html). Does anybody know where I could buy a small quantity of this or something like it in the SF Bay Area? I checked at Alco in San Leandro and didn't see anything like it (maybe I missed it, that place is big). My frame only needs to be about 4'x5' so I am not exactly needing to frame a building or anything.
