B-Line Eaton series open racks, Steel, #12-24 mounting hardware, Flat black powder coat, Tow mounting spaces required, Low profile rack mounted venti

Two mounting spaces, so 2U of rack height. The shelf panel itself is 3.42 inches high, which is why it fits in a 2U opening rather than 1U. Plan your rack elevation with two free spaces before ordering.

It ships for #12-24 mounting hardware, which is the thread B-Line uses on its open frame racks. If your rack rails are tapped 10-32, the supplied screws will not thread in and you will need the correct 10-32 hardware for those rails.

The shelf is 16 inches deep and 17.25 inches wide, sized to sit between the rails of a standard 19-inch rack. Equipment deeper than 16 inches will overhang the rear edge, so for deep servers or UPS units you want a deeper shelf or a four-post rail kit instead.

A ventilated shelf like the SB745V2316SFB is perforated so heat from switches, media converters, and small appliances rises through the deck instead of being trapped underneath the next device. Choose a solid shelf when you are setting down loose tools, manuals, or small parts you do not want falling through, or where you want a flat writing surface in the rack.

It is built for B-Line Eaton series open frame racks, mounting to the front rails only, so a two-post open rack is exactly what it is for. In a four-post enclosure you can still bolt it to the front rails, but for heavy or deep equipment in a cabinet a front-and-rear supported shelf carries the load better.

Formed steel with a flat black powder coat, so it matches the standard black finish on B-Line series open frame racks and resists scuffing in a busy IDF closet. The shelf weighs 10.7 pounds on its own, which is worth knowing when you are figuring total load on a two-post rack.

Order it as Eaton B-Line SB745V2316SFB. That number covers the 16 inch deep ventilated low profile shelf in flat black.
