B-Line Eaton series open racks, Double sided, Steel, Telco gray powder coat, 51 mounting spaces, Top angle style, Seismic Zone 4, network bay closed

Yes. The Eaton B-Line SB5863096TG open frame rack is built as a Seismic Zone 4, network bay closed duct rack, so it is the version to specify where the drawing calls out Zone 4 seismic bracing. It is also UL Listed. Anchoring to the slab and any overhead bracing still has to follow the engineer's detail for the room.

51 mounting spaces on rails punched with 12-24 panel mounting holes. That means your gear needs 12-24 rack screws and cage nuts are not part of the picture. Plan panel stacking against the 51 spaces before you order, since a fully loaded 51-space bay leaves no spare room for later growth.

The rack is listed at 96 in height, 96 in length/depth and 19 in width, and it weighs 130.51 lb. At 96 inches tall it will not go upright through an 80 inch door opening, so plan to move it flat and stand it up in the room, and check slab-to-ceiling clearance before you tip it up.

Open frame. The Eaton B-Line SB5863096TG is a two-post style open rack with a top angle style top, not a four-sided enclosure with doors. If you need lockable security or airflow containment around the equipment, an open frame is the wrong choice and you want a cabinet instead. Open frame is the usual pick for telco/network bays where cable access from both sides matters more than physical security.

It refers to the cover/duct configuration: the SB5863096TG is a double sided, network bay closed duct rack. The closed duct runs the cable pathway with the rack rather than requiring a separate overhead tray at the bay itself, and double sided means it is set up to serve cable on both sides of the bay. Useful when you are ganging bays in a row in a telco room.

What is defined here is the rack itself: steel frame, telco gray powder coat, top angle top, 51 mounting spaces on 12-24 rails, in the closed duct network bay configuration. Mounting screws, vertical cable managers, ground kits and seismic anchor hardware are separate line items on a rack build, so budget those alongside the bay.

It ships in telco gray powder coat over steel, which is the standard finish used across Eaton B-Line telco bay product, so it lines up visually with existing gray B-Line rows. If your room was built out in black, this one will not match.
