B-Line Eaton series open racks, Steel, Yellow zinc finish, 12-24 panel mounting holes, 67 mounting spaces, Top channel style, Seismic Zone 4, network

Yes. The SB5778084YZ is an open frame rack with 67 mounting spaces and 12-24 tapped panel mounting holes, which is the standard telecom/network rail tapping used for 19-inch EIA panels and switches. Overall frame width is 23 inches, which is what a 19-inch panel opening works out to once the rail flanges are included.

It is built as a Seismic Zone 4 network bay closed duct rack, so it is the version specified for the highest seismic zone rather than a standard commercial frame. Seismic performance still depends on anchoring the base to the floor structure and bracing the top channel per the job's structural details.

No cage nuts needed. The rails are tapped with 12-24 panel mounting holes, so panels and equipment bolt straight in with 12-24 rack screws. Square-hole gear that ships with cage nuts will need 12-24 hardware instead.

The frame stands 84 inches tall, which is the common full-height telecom rack size and clears an 8-foot ceiling with room for overhead ladder rack. Depth is listed at 84 inches as well and width is 23 inches, so plan aisle space accordingly.

Yes, the rack carries a UL Listed marking, which is usually what an inspector or a hospital/education facility spec is looking for on a network bay frame.

An open frame two-post style network bay like the SB5778084YZ gives full access to patch fields and switch cabling from both sides and is what most telecom rooms use for patch panels, fiber housings and network gear. Choose an enclosed cabinet instead when you need lockable physical security, dust control, or front-to-back airflow containment for servers.

The frame is steel with a yellow zinc plated finish. Zinc plating gives corrosion protection and, unlike a painted or powder coated rack, it leaves a conductive surface at the joints, which matters when the rack is part of a bonded telecom grounding system.

The rack weighs 118 lb bare, before any equipment. At 84 inches tall that is a two-person lift to stand up and hold plumb while the base is anchored.

The top channel runs across the head of the frame and is the tie-in point for overhead cable runway and for bracing the rack back to the structure or to adjacent bays in a lineup. It is also what lets several of these frames be ganged into a continuous network bay row.
