B-Line SB747S2310STG Eaton series open frame racks, Steel, #12-24 mounting hardware, Three mounting spaces required, Telco gray powder coat, Single sided rack mounted shelf solid shelf, Used to support monitors, CPU's and modems

Plan on three rack mounting spaces (3U) for the SB747S2310STG. Its overall height is 5.19 inches, so if you are laying out a rack elevation, block off three continuous spaces for it before you assign the gear above and below.

Yes. The SB747S2310STG measures 22.31 inches wide overall, which is the full rail-to-rail flange width used on standard 19 inch EIA open frame racks, and it mounts with #12-24 hardware, the common thread on B-Line open frame rack rails.

The shelf gives you 10 inches of usable depth. It is a solid steel shelf meant to carry monitors, CPUs and modems, so a compact desktop tower or a monitor base fits, but anything with a footprint deeper than 10 inches will overhang the front or rear edge.

Single sided. The SB747S2310STG attaches at the front rails only, which is what you want on a two-post open frame rack. If your rack is a four-post cabinet and you need rear support as well, a single sided shelf is not the part for that.

The SB747S2310STG is the solid version, a flat steel panel with no perforations. Solid is the choice when you are setting a monitor, modem or small CPU on it and want a continuous surface with nothing to catch feet or cables. If the equipment you are setting on it generates heat and relies on airflow up through the bottom of its case, a vented shelf is the better pick.

It uses #12-24 mounting hardware into the rack rails. The shelf itself weighs 8.4 pounds, light enough for one person to hold in place while starting the screws, though on a tall rack a second set of hands makes it easier.

It is finished in telco gray powder coat, the same finish B-Line uses on its telco-gray open frame racks and ladder rack, so it blends into an existing telco gray frame rather than standing out the way a black shelf would.
