Part Number: PP0020 Product Description: "Shelf for 19 inch rack, 20 inches deep in Two Pieces" Category: Installation Racks Shelves Price: $78.92 Product Weight: 10 lbs Full Size Picture Hole Alignment Problem?? On relay racks, the holes are not evenly spaced. They're grouped into threes, each group to accomodate a 1U panel. If the holes don't line up for you on the first try, try moving panel up or down one or two holes. Observe in the animation how the holes are lined up when the panel is at the top and then how the panel has to be moved down three holes in order to have both holes lining up again.
