B-Line Eaton series open racks, Steel, Computer white finish, Self supporting relay rack, 11 gauge, ASTM A570

Yes. The SB5554084TG is a 19 inch wide rack, which is the standard EIA panel width for rack-mount network, telecom, and audio gear. It stands 84 inches tall, the common full-height relay rack size for a communications or IT room.

It is a self-supporting relay rack, so it stands on its own base channel rather than hanging off a wall or cabinet. Standard practice in a comms room is still to anchor the base to the floor and tie the top into overhead ladder or cable runway for seismic and load stability, but the rack itself does not rely on a wall for support.

11 gauge steel to ASTM A570, the hot-rolled carbon steel sheet spec. That is the heavier end of open-frame rack construction, which is why it can carry loaded equipment as a free-standing frame rather than needing a full enclosure.

Yes, the Eaton B-Line SB5554084TG carries a UL Listing, which is normally the first thing an institutional or MRO spec asks for on rack and frame equipment going into a government, healthcare, or education comms room.

An unequal flange rack has flanges of two different widths on the upright, so the mounting face sits off-center. That gives you a deeper channel on one side to route and conceal cable, and the closed duct construction encloses that run instead of leaving it open. Use it where you need integrated vertical cable management in the frame itself; use a plain equal-flange open rack where cable is managed entirely by separate vertical managers or overhead runway.

The rack is configured double sided, so it is set up for access and mounting from both faces rather than a single front-only panel run. Plan floor placement with clearance behind it, not against a wall.

Yes, it is a top channel style rack, so the upper end of the frame is finished with a channel you can use to tie the rack into overhead ladder rack or cable runway and to bolt racks together in a row.

The rack weighs 83 lb bare. That is a two-person lift to stand up and plumb an 84 inch frame safely, and you want it anchored before any equipment goes in the rails.
