Yes. The SB5871140TG is a 19 inch wide open frame network bay rack with 77 mounting spaces, so it takes standard 19 inch EIA rack-mount switches, patch panels and servers. At 77 spaces you get the full usable height of a tall telco bay rather than the 45 spaces of a typical seven-foot rack.

The SB5871140TG is built as a Seismic Zone 4 network bay open duct rack, which is why it uses the heavier top channel frame style. That makes it the right choice for California and other high seismic design regions where the structural engineer calls for a zone 4 qualified bay. It is also UL Listed.

What ships is the open frame bay itself, steel with Telco gray powder coat, 77 mounting spaces, top channel style. Vertical cable managers, ladder rack and overhead duct, grounding busbar, and the concrete anchors the seismic detail calls for are separate line items. On a Seismic Zone 4 job the anchor type and size comes off the engineer's drawing, so order that hardware to the drawing rather than assuming a kit is included.

An open frame bay like this one leaves equipment accessible from all sides and lets cable run freely into overhead duct and ladder rack, which is why telco and network closets use it. It gives no physical security and no airflow containment, so if the room is shared, public facing, or you need locked access or front-to-back cooling, specify an enclosed cabinet instead. This 140 in tall, 19 in wide bay with 77 spaces is aimed at a dedicated, controlled equipment room.

It weighs 147.83 lb bare. That is a two-person lift at minimum, and because it is 140 in tall the practical problem is length rather than mass, getting it through doorways and standing it up. Budget for two or three installers plus anchoring to the floor slab before any equipment goes in.

Order Eaton B-Line part number SB5871140TG. That number covers the 140 in tall, 19 in wide, Telco gray steel open duct bay with 77 mounting spaces in Seismic Zone 4 configuration.

Frame is steel to ASTM A569 with a Telco gray powder coat. Powder coat over steel is standard for indoor telecom bays, and Telco gray is the common shade so this bay lines up visually with existing runs of telco racking and ladder rack in the same room.
