B-Line Eaton series open racks, Steel, Yellow zinc, 12-24 panel mounting holes, 66 mounting spaces, Top channel style, Seismic Zone 4, network bay op

Yes. The Eaton B-Line SB5777096YZ is built as a Seismic Zone 4 network bay open duct rack, so it is the version to specify where the drawing calls for Zone 4 anchorage. The frame is ASTM A570 grade 33 steel and the assembly is UL Listed.

66 mounting spaces on a frame 96 inches tall. That is the usable panel capacity for switches, patch panels and rack-mount gear on a full-height network bay.

The rails carry 12-24 panel mounting holes, which is the standard tapped thread for EIA equipment in North American telecom rooms. Gear with clearance-slot ears mounts directly with 12-24 screws, no cage nuts needed.

Plan for a footprint based on a 23 inch width and 96 inch height, with a stated depth dimension of 96 inches on the spec sheet. The unit weighs 124 lb, so it is a two-person set and needs floor anchoring appropriate to a Zone 4 seismic install.

An open rack like the B-Line SB5777096YZ leaves all four sides accessible for cable dressing and passive cooling, which is what you want in a secured MDF or IDF room where physical access is already controlled. Choose an enclosed cabinet instead when the equipment sits in shared or public space and needs locked doors, or when you need contained airflow. This one is a top channel style network bay, built to gang into a row with duct and ladder rack overhead.

Top channel style means the rack is topped with a channel section made to carry overhead cable runway and to tie adjacent bays together in a lineup. That is how these network bays are ganged into a row with ladder rack landing on top. The channel is part of the load path in a Seismic Zone 4 layout, so follow the engineer's bracing detail for the row.

It is UL Listed, which is what most institutional and government submittals ask for on rack and frame products. Pair that with the Grade 33 ASTM A570 steel construction and the Seismic Zone 4 rating when you submit it.

Yellow zinc is a conductive plated finish over steel, unlike a powder coat, so it does not insulate the frame the way paint does. The rack is steel throughout with a yellow zinc surface finish. Bond it per your telecom grounding detail with a listed rack ground kit and busbar.
