If you have a
Trillium 4500 and live near an ALDI market, they have 23.75"w x 16"L x 12"H stackable wire mesh shelves for $7 a piece that fit perfectly in the closet.
I was't sure on the depth of the closet but ALDI sells out of their weekly deals quickly (and does not restock) so I figured I could buy them and return if needed. To set them up I left all three in the nested position, turned the long side vertical to get them in the closet, then rotated them 90 degrees then stacked them in the closet.
There was a little flexing needed to rotate them 90 degrees in the closet but I did not need to distort the wire to do so. It is about as a good a fit as I could have hoped for. It cost $22.30 and took 2 minutes to set up.
I was going to do a PVC set up (a really good option), but when I saw these I had to give them a shot. In the amount of time I would have spent at home depot just making sure the PVC Tee fitting matched the size on the box, I had these purchased and installed.
I found the same wire shelves at Walmart.com (see the link below) and Staples.com. $18.99 is not $7.99 but it still seems worth $60 for such an easy set up and exact fit; the PVC/Plywood method would cost $40+ in materials if you don't have them laying around.
