Where to buy some 45 degree angle stock

I need some 45 degree angle stock for a hanging planter my wife asked me to build. Anyone have or know of a source? To give the planter strength I would like the brackets to be about 12" long.

Duane, welcome aboard. I don't know if I completely understand your request. I can't even tell if you are looking for wood or metal. We like info here Duane, give us an approximate location so we even have an inkling of where we could send you. Also, a little more information on the planter itself.
