When I was storing many RK05 carts, long ago, I had a 7 foot high steel shelving unit. For what ever reason, it was supplied with holes drilled in all the shelves, a few inches apart, in a neat row about 2 inches from the front of the shelf, and in another row across the back. I used cheap paneling to close off the back of the space between two of the shelves, and the sides, to keep the dust out. Threaded rods through the holes at front and back left gaps about the right size for the packs to be stored on edge. I even constructed a cover out of 3/8" plywood, with a 3 inch lip around it to accommodate the fact that the shelves were about 2 inches too shallow. Don't have shelving like that? You'll have to come up with something else. Maybe wood shelving with 3/8" dowels between them. -T At 04:01 AM 3/16/2014, you wrote: 780 .
