B-Line Eaton series open racks, Aluminum, Flat black powder coat finish, Double sided rack mounted shelf. Heavy duty, solid shelf, Shelves and #12-24

Depth is 20 inches, so it carries gear up to roughly that footprint. It is a solid shelf rather than vented or cantilever, meaning equipment sits fully supported across the whole surface instead of overhanging. Deeper chassis will hang past the front or rear edge and should go on rails or a deeper tray instead.

It ships with #12-24 mounting hardware, which is the thread most tapped-rail equipment racks use. If your rack rails are #10-32 or square-hole with cage nuts, the included screws will not thread and you will need to source the matching fasteners.

The shelf is 6 inches high. Since a rack unit is 1.75 inches, that works out to just under 3-1/2 RU of vertical panel space, so plan on 4U of clearance in the frame when you lay out the rack.

It is aluminum with a flat black powder coat, and the shelf itself weighs 5.4 pounds. Aluminum keeps the dead weight off a two-post open frame, which matters when you are stacking several shelves on one rack, and the powder coat holds up in dry indoor equipment rooms. For very heavy battery or UPS loads, a welded steel shelf or floor-supported rails is the better call.

A solid shelf, which is what the SB596V19153AFB is, gives a continuous flat surface for equipment with feet, small chassis, or loose gear that could fall through a grid. Go vented instead when the box underneath draws cooling air up through the bottom or when you need cable to pass straight through the shelf plane.

Order Eaton B-Line model SB596V19153AFB. That single part number covers the aluminum double sided, heavy duty solid shelf in flat black, 19.31 inches wide by 20 inches deep by 6 inches high, with the #12-24 hardware in the box.

The shelf is finished in flat black powder coat, the same finish B-Line uses across its open frame rack line, so it reads consistent alongside existing black racks, panels, and cable managers in a data closet.
