First I make a cradle to fit the EMT conduit. The long pieces are 3 feet 9.75 inches long. The short pieces are 20"

Then I put the EMT conduit there.

Then I close the top of the cradle.

Home depot will cut a 4x8 piece of plywood right down the middle for a perfect fit. This actually is strong and stable enough to make a nice little bed. Home depot sells a pad that fits this perfectly.

The shelf can be used for storage. I will likely make a second shelf about 3' higher than the first shelf to make a two shelf unit.

I make the top shelf so that it can be the bottom cradle to put in the rental truck to move the poles from the storage to the rental truck. So, the top will become the bottom while in the truck, and vice versa while in the storage unit.

After I put the fittings with upward pole mounts, I position a piece of plywood.

I trace the fitting locations so I can cut the sections out to fit the lower shelf.

I put the poles together for the complete shelf frame. You have to be prepared to take things slow and keep cutting poles an inch or so shorter because of the way the fittings are made. You just have to be flexible and keep notching here and there while you're fitting it together. The top vertical poles are 31-3/4 inches long. I did this because we have an abundance of 8' vertical poles for our canopies, this wastes very little, and the stacked boxes fit very nicely.

I put on the plywood. Now we have bunk beds.

What was once a monumental waste of space in the storage and the rental truck now holds quite a bit of cargo and keeps it organized.
