B-Line Eaton series open racks, 340 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 38 mounting spaces, Top angle style, Seismic Zone

Yes. The SB5867084TG is built as a Seismic Zone 4 network bay open duct rack, and it is UL Listed. The frame is ASTM A570 grade 33 steel. If your drawings call for seismic-rated equipment racks in a Zone 4 jurisdiction, this is the rack type specified for that duty; anchoring to the slab per the structural detail is still the installer's responsibility.

Rated load capacity is 340 lb. That is the total for everything you hang on the rails, so add up switch, patch panel, and any rack-mount UPS weights before you load it. The rack itself weighs 122.85 lb, which matters for getting it into a closet and for the floor anchor detail.

The rails are tapped 12-24 panel mounting holes. Standard 19 inch EIA gear with 12-24 screws mounts directly, no cage nuts needed. If your existing panels are hardware-matched to 10-32 or square-hole cage nut rails, you will need to swap screws or order the right hardware.

Footprint works out from a 23 inch width and an 84 inch length/depth dimension, with the frame standing 84 inches tall. Plan the closet layout around that plus working clearance front and rear, since an open rack is accessed from both sides.

An open duct rack like the SB5867084TG is the choice when the room itself is secured and you want unrestricted access and airflow to patch panels and switches. It gives 38 mounting spaces with open sides for cable duct runs. A locking enclosure is the better call where the gear sits in a shared or public space and needs physical security, or where you need door-mounted fans and filtration.

Top angle construction gives you a horizontal angle across the top of the frame, which is what overhead ladder rack and cable runway tie down to. If you are running a runway between bays in a network room, this style is the one built to take that connection.

Finish is a telco gray powder coat over steel, the standard color used across telecom and network bay hardware, so it lines up with existing gray B-Line bays and ladder rack in the same room. Powder coat over ASTM A570 grade 33 steel also holds up better than paint in a high-traffic MDF or IDF.
