B-Line Eaton series open racks, Telco gray powder coat, 12-24 panel mounting holes, 48 mounting spaces, Top angle style, Seiemic zone 4, network bay

The Eaton B-Line SB5766140TG network bay rack provides 48 mounting spaces of usable rail height. That is enough to take a full complement of patch panels, switches and horizontal managers in a single bay without stacking a second frame.

The rails are punched with 12-24 panel mounting holes, which are tapped threads rather than square cage nut openings. You mount gear directly with 12-24 screws. If your equipment ships with M6 or 10-32 hardware, order 12-24 rack screws to match the frame.

Yes. The SB5766140TG is built as a seismic zone 4 network bay open duct rack, so it is the right frame for installations in the highest seismic design category. It is steel construction and UL Listed. Anchoring to the slab per the seismic detail on your drawings is still the installer's responsibility.

Plan the space around 140 in height, 140 in length/depth and 23 in width as published for this bay. The 23 in width is the standard open-rack footprint that lines up in a row, but the 140 in height means you need clear ceiling and overhead cable tray coordination before it goes in. It weighs 137 lb, so it is a two-person set and a slab anchor job.

An open duct rack such as the B-Line network bay is for secured telecom and IDF rooms where you want all-sides access, free airflow and easy cable dressing between bays. Choose an enclosed cabinet instead when the equipment sits in a shared or public area and needs locking doors, or where you need containment and filtered airflow. This one is an open frame with a top angle style for overhead ladder and duct attachment.

The top angle gives you a flat mounting surface across the top of the bay for running ladder rack, cable runway or overhead duct into the frame. In a multi-bay lineup it is what ties the runway to each rack, so it matters if your cabling comes in from above rather than under a raised floor.

Order it as Eaton B-Line SB5766140TG. That number covers the Telco gray, 12-24 threaded rail, 48-space seismic zone 4 network bay configuration, so there is no separate finish or rail suffix to specify.

Yes, the SB5766140TG carries a UL Listed marking, which is typically what a facilities or MRO spec calls for on telecom rack frames. Combined with the seismic zone 4 rating, it covers the two items most commonly written into a data room submittal.

The finish is Telco gray powder coat, the standard color used across telecom and network bays, so it lines up visually with most existing open frame racks in an IDF or MDF room. Powder coat over steel also holds up to rack screws being driven and backed out repeatedly.
