The milk crate. Standard furniture in every dorm room. We have used them as steps and storage. To hold up shelving and our bottoms, including bottom boards.... they are the plastic lightweight cinder block..... A million and one uses!
Well I found another use for the simple crate.
A 6 gallon milk crate is the same length as the outside of a frame. It was like it was meant to bee....
It fits 8 frames with a little room to spare and 9 if you have cut them down for small cell (1 1/4"). It should be deep enough to hold deep frames but I am running all mediums so I can not test fit to be sure.
I did a quick search for this use and turned up nothing. I am sure this is not an original idea (I never have them even when I am sure I must have) but I did not find it reference here.
