My wife called me at work today and said someone was throwing out some metal shelves. She asked if we needed them for anything. Shelves? You bet!
So I got home, cleaned them up, tightened the bolts and proceeded to stack trays of cans on them. The trays I use fit perfectly! I figure it'll hold about sixteen trays, not including the very top shelf. Each tray holds 50 cans. So I've just been granted space for about 800 cans.
Just what I needed!!!
