B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 43 mounting spaces, Telco self-supporting aluminum relay r

43 mounting spaces on a frame 108 inches tall. That is the usable panel capacity, so plan your switch, patch panel and rack-mount UPS stack against 43 spaces rather than assuming a standard 45U cabinet count.

Yes. The frame is 19 inches wide, the standard EIA equipment width, and the rails are punched 12-24, which is the thread most telco and network panels ship for. No cage nuts needed, you thread 12-24 screws straight into the rail.

The SB5551084TG is built as a seismic zone 4 network bay open duct rack, and it is UL Listed. It is a self-supporting relay rack, so it stands on its own footprint, but seismic zone 4 work still means anchoring to the slab and, in most builds, bracing to overhead ladder rack per the engineer's detail.

An open frame rack such as this Telco style B-Line suits a secured telecom or MDF room where you want all four sides of the gear reachable and cabling dressed in the open. Pick an enclosed cabinet instead when the room is shared, publicly accessible, or dirty, or when you need lockable doors and directed airflow. Open racks do not give you either.

The rack is the frame and rails only. Budget separately for floor anchors, vertical and horizontal cable management or duct, ladder rack and any grounding busbar kit, plus 12-24 rack screws to match the punched rails.

83 pounds for the rack. That is manageable for two people to walk in and stand up, but with 108 inches of length it is an awkward carry for one, and the load goes way up once panels and switches are populated, which is what your floor anchoring has to account for.

The finish is Telco gray powder coat, the common finish on telco relay racks and bays, so it lines up visually with existing gray frames. The frame itself is steel, not aluminum, so if you are standardizing on an all-aluminum bay line the material differs even though the color reads the same.
