Looking for Alu double channel extrusion

[Armac]

Hi,

First post from new forum member.

I'm looking for a source of the Alu double channel extrusion typically used in the masthead of lower tech Alu spars. Something like two 3/4" channels x about 2-1/2" high and a 3/16" or so wall thickness.

Thanks,

Rob

Online Metals (dot com) has a good selection of profile extrusions; they're usually OK if you only want small amounts. I can't recall ever seeing "double channel", but I've bought stuctural aluminum channel from them before, as well as plate and rod stocks.
Good luck
Ben

Yeah, I've looked there and pounded google, but thanks for the suggestion.

It's useful stuff, not only for mastheads but sheave boxes also.
