B-Line Eaton series open racks, Aluminum, Includes #12-24 mounting hardware, Flat black powder coat, Low profile rack mounted shelf ventilated shelf

Yes. The SB745V2319AFB is a rack mounted shelf with a 19 inch depth dimension and an overall width of 21.25 inches, which covers the rack rails plus the mounting flanges on a standard 19 inch EIA rack. Height is 3.42 inches, so plan on 2U of vertical space in the frame.

Mounting hardware is in the box. The shelf ships with #12-24 screws, which is the thread used on tapped-rail open frame racks. If your rack has square punched rails rather than tapped holes, you will need cage nuts to accept the screws.

Aluminum, finished in flat black powder coat, and it weighs 4.9 lb. The light weight matters if you are hanging several shelves in a two-post open frame rack where total load on the rails is a concern, and aluminum is the better choice than steel in damp or coastal telecom closets.

A ventilated shelf like the SB745V2319AFB is the one to use under anything that sheds heat on its own, small switches, media converters, power bricks, DVRs, since the perforations let air move through instead of trapping it against the tray. A solid shelf is the better pick only when you are setting down small loose items or something with feet that would catch in the perforations.

The part number is SB745V2319AFB, an Eaton B-Line series low profile ventilated rack mounted shelf, aluminum, flat black. That MPN covers the shelf and the #12-24 hardware together as one item.

The shelf itself is 3.42 inches tall, so budget that plus the height of whatever sits on it when you lay out the rack elevation. Because it is a low profile design, there is no deep side rail eating into the space above the tray.

It is flat black powder coat, which is the standard black open frame rack finish B-Line uses, so it reads as a match alongside black racks, cable managers and panels. Against a clear or grey anodized aluminum rack it will contrast.
