B-Line Eaton series open racks, Steel, Telco gray powder coat, 48 mounting spaces, Top channel style, Seismic Zone 4, network bay open duct rack, AST

The B-Line Eaton series open duct rack, model SB5872140TG, is built as a Seismic Zone 4 network bay rack, so it is rated for the most demanding seismic zone classification. It is also UL Listed. Anchoring to the slab and any overhead bracing still has to follow your structural engineer's detail for the room.

48 mounting spaces, which is the count of equipment mounting positions on the uprights. Plan your switch, patch panel and PDU stack against that figure before ordering, since an open duct rack has no spare depth behind a door to absorb an extra panel.

An open frame duct rack gives you access from all four sides and unrestricted airflow, which is what most telco and network bay rooms want for patch panels and switches. Go to an enclosed cabinet instead when you need physical security, dust control, or door mounted cooling. This B-Line unit is the open style, top channel design, with no doors or side panels.

Yes. The top channel design at the head of the frame is what ties a bay into overhead ladder rack or runway and links adjacent bays into a continuous row. If you are building a row of network bays, the channel is the part that makes them line up and share the runway above.

Order Eaton B-Line part number SB5872140TG. That single part number covers the 140 inch high, 19 inch wide steel open duct rack with 48 mounting spaces in Telco gray powder coat.

Steel to ASTM A1011SS, finished in Telco gray powder coat. That is the standard finish in telecom and network rooms, so it matches existing bays lined up in the same space. Powder coat holds up to handling during equipment changeouts better than a wet paint finish.

147.83 lb for the frame itself. That is a two person lift to stand up, and at 140 inches tall you want it walked up rather than tipped in a finished room. Add your equipment load on top of that when sizing floor anchors.
