B-Line Eaton series open racks, Aluminum, #12-24 mounting hardware, Three mounting spaces required, Flat black powder coat, Single sided rack mounted

Plan on three mounting spaces (3 RU) for the SB747V2315AFB solid shelf. The shelf panel is 5.19 inches high, which is why it eats three holes' worth of rack space rather than one or two. Count those three spaces as consumed even though the usable shelf surface sits inside them.

Yes. The SB747V2315AFB is supplied for #12-24 mounting hardware, which is the standard thread on Eaton B-Line open frame racks and most tapped-rail equipment racks. If your rails are 10-32 tapped or square-hole cage nut style, you'll need the matching hardware for those rails instead.

It's a single sided shelf, meaning it fastens to one pair of rails (the front posts) and cantilevers back. Depth is 15 inches, so gear deeper than that will overhang. On a two-post open rack with nothing to support the rear, keep heavier items toward the rails.

Solid, not vented. A solid deck gives you continuous support for small switches, media converters, power bricks, or test gear that has no rack ears, but it blocks airflow up through the shelf. For equipment that pulls cooling air from below, pick a vented shelf instead.

The ordering part number is SB747V2315AFB: a 15 inch deep solid aluminum shelf, flat black powder coat, single sided, 3 mounting spaces, for #12-24 hardware. Specify that number for every closet and the shelves will match visually and mount identically on any tapped 12-24 open rack. Budget three rack spaces per shelf when you lay out the elevations.

Aluminum, finished in flat black powder coat. The aluminum construction is why the shelf itself only weighs 4.2 lb, which keeps the load on a cantilevered front-rail mount lower than a comparable steel shelf. The flat black matches B-Line series open frame racks in the same finish.
