The first shop I ever worked in had been an old sign & glass company. Naturally everything was stored vertical, except for the thousands of old pounce patterns. They were above the layout tables in a chicken wire cage.. Sorry these are the best pics have of this rack. The rack only has a 4'x8' footprint and was 9' tall. Because it wasn't against the wall, it would hold 10' pieces and even 12' in a pinch. Maybe not great for a high volume shop, but I've always been a custom, one off shop and the design served me well for years.
Like Gino says, the drops are gravy. I saved everything. Need a test piece for paint? Got it. Need a 3/4" match-plate to set J bolts? Got it. Need an 8" x 96" piece of ACM, without using a whole sheet? Got it. Need a chunk of OSB to lay across a ditch to get the wheelbarrow in? Got it. I went through a fire and the soot ruined most everything in the rack. I remember taking it to the landfill and every time I chucked a piece, I was like there goes 10 dollars, there goes 15 dollars. and another 20 dollars.
