So I had a thought while in the car today. (No I'm not going to do it, but simply theorizing about it.) Dextron, that slotted angle steel often used for mounting garage doors. Slots in it every say 1" on center of various types of slot or hole with a "L" shape of 14 to 16ga high carbon steel in having 1.1/4" to 1.1/2" legs to it. Given the spacing, it might make in some ways a decent closet rod - not that I’m considering such a ting at home but for a debate topic, consider it as this. What if you were to use such a thing for closet rod. Dispersed but at times very heavy weight to it. So now the real question, structurally is it stronger for the 1.1/2" strut to be leg down in hanging from the part of it in a vertical position, leg up in hanging from the horizontal portion of it, or legs folded together in hanging from both legs? If legs folded, is it best for the fold portion to be up or down?
