B-Line Eaton series open racks, Steel, Flat black powder coat, 39-7/16" self-supporting relay rack, 11 gauge, ASTM A570

It's a two-post open frame relay rack, model SB556036XUTG. Open frame means no side panels or doors, so you get access to cabling from both sides and free airflow around the gear. If you need a lockable enclosure with a secured front and rear, an open relay rack is the wrong choice; pick an enclosed cabinet instead. Where the room itself is secure, the open rack is faster to terminate and service in.

Yes. The rack is built to the 19 inch mounting width, which is the standard for network switches, patch panels, and rack-mount servers. Anything built to 19 inch EIA rack spacing will land on the rails.

The frame is 11 gauge stock to ASTM A570. That's a structural-grade sheet spec, which is why the rack carries loaded switchgear and patch fields without a base cabinet under it. The complete frame weighs 27.5 lb, so it's a one-person carry into a closet but should be anchored once populated.

Yes, it's a double sided configuration, so gear and cable management can be hung off either face of the two posts. That's what makes an open relay rack useful in a tight closet: patch panels front, switches rear, and every termination stays reachable.

It's styled for customer premise use, meaning building telecom rooms, IDF and MDF closets, and small equipment rooms rather than aisle-contained data center rows. For a property manager standardizing riser closets across a portfolio, a half-height self-supporting relay rack like this is the usual fit.
