B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 66 mounting spaces, Top channel style, Seismic Zone 4, net

Yes. The Eaton B-Line SB5777096TG is built as a Seismic Zone 4 network bay open duct rack, so it is intended for installations in the highest seismic design zone. It is also UL Listed. It is a steel frame and needs to be anchored to the floor and, for a network bay run, tied to overhead structure the same way any Zone 4 bay is secured.

The rails are drilled and tapped 12-24 panel mounting holes, so equipment bolts straight in with 12-24 screws. No cage nuts and no square-hole clips. If your gear ships with 10-32 or M6 hardware, order 12-24 rack screws to match.

66 mounting spaces on a 96 inch tall frame. That is usable RU for patch panels, switches and rack-mount gear from top to bottom. Plan your panel and cable manager layout against 66 RU, not the full frame height, since the top channel takes part of the structure.

Frame is 96 inches tall and 23 inches wide, and the rack weighs 124 lb before any equipment. Allow ceiling clearance above 96 inches for the top channel and any overhead ladder rack or duct it ties into, plus front and rear service aisles since this is an open frame with no doors or side panels.

An open frame like the B-Line SB5777096TG is the right call for telecom and network bays where you want unrestricted access to both sides, open airflow, and easy cable routing into overhead duct. It has no doors, no locks and no side panels, so it is not the choice where you need physical security of the equipment or dust and airflow containment. For those, a fully enclosed cabinet is the correct product type.

Top channel style means the frame is capped with a channel across the top, which is what you land overhead cable runway and duct onto when the racks are ganged into a network bay. It is the configuration used when cable enters from above rather than from a raised floor.

The SB5777096TG is finished in Telco gray powder coat, the standard central office and telecom room color, so it lines up visually with existing Telco gray bays and ladder rack. Powder coat over steel also holds up in an MRO environment better than painted sheet.
