I just bought a full set of Grip Latch boxes; roll away, intermediate, and top box. The roll away is set up in a way I don't like and I wanted to move the drawers around to be better for what I want to use it for, but I can't figure out how to remove the side rails from the box. I can get the drawers out no problem, but can't see a way to remove the side rails without bending something. Anyone know how to get these things out?

Thanks,

Joe
