Have a variety of this ITEM brand structural aluminum extrusion. In the pics the extrusion on the right is the 40mmx40mm (~1.5"x1.5") and sells new for about 53 cents per inch(2007 pricing). Lengths vary from about 18" to 11' with most lengths about 42". Most of the sections have milling for connectors as seen in the pics. We are selling this for $2.00 per foot. The extrusion on the left is the 40mmx80mm (~1.5"x3.0")and sells new for 93 cents per inch(2007 pricing). Lengths vary from 35" to 59". We are selling this for $4.00 per foot. I also have some 12' lengths of this with milling for connectors at both ends and it sells for $60.00 each. Great stuff if you need to build work benches, equipment frames, etc. Cuts with a miter saw with carbide tooth blade. Will also consider trades, prefer hunting and fishing stuff, but tell me what you've got. Currently I'm in the need of wood fence panels and will trade. Reply to the link for info and directions.
