...Storables has a shelving system called Industrial Post Steel Shelving...
Here's the
IP Shelving on the Storables site:
Click to view attachmentWe have a shelf like this in our house, holding a TV and associated equipment, plus books and stuff. It appears to be common in commercial kitchens. Similar systems are sold by IKEA, Home Depot, Costco, etc, but I've never seen one with shelves small enough for a trailer closet before - good find!
The grooves in the post don't look deep enough to hold anything... until you realize that the holes in the shelves are tapered tubes, and the sleeves are tapered to match, so the load on the shelf jams them together and makes the ridges on the sleeves engage the grooves very effectively.
Susan's 14"x18" shelves are the smallest available from this supplier, and the only size which would fit my Boler closet - but they would be a pretty good fit, with the 14" as the width.
At $14 a shelf, plus $7 a post, this is not a really cheap system, but is is adjustable and very strong.
