B-Line Eaton series open racks, 340 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 41 mounting spaces, Top channel style, Seismic Zon

The SB5867090TG provides 41 mounting spaces on a frame 90 inches tall. That is usable panel space for 41U of switches, patch panels, and rack-mount gear, laid out on 12-24 threaded panel mounting holes.

The rails on this Eaton B-Line open rack are tapped 12-24, so 10-32 screws will not thread. Order 12-24 rack screws and make sure any cage-nut-less gear you are mounting is being fastened with 12-24 hardware. Equipment ears themselves are standard EIA slots, so the thread only affects the screws you buy.

Yes. The SB5867090TG is a Seismic Zone 4 network bay open duct rack, which is why it uses the top channel style frame, and it is UL Listed. Zone 4 rating depends on the rack being anchored to the slab and braced per the installation instructions, so plan for floor anchors and overhead or top-channel bracing as part of the job.

Load capacity is 340 lb of equipment. The frame itself weighs 125.23 lb. For a full bay of switches and patch panels that is usually plenty, but a rack loaded with multiple UPS units or heavy chassis switches will exceed 340 lb, and in that case you want a heavier-duty two-post or a four-post cabinet instead.

Stated dimensions are 90 inches height, 90 inches length/depth, and 23 inches width. Confirm your ceiling height before ordering a 90 inch frame, particularly in a retrofit telecom closet with a dropped ceiling, and allow front and rear working access since an open rack is meant to be reached from both sides.

An open rack like the SB5867090TG is the right call in a secured telecom room or MDF where you want unrestricted airflow, easy cable access from both sides, and fast moves and changes. It gives no physical security and no dust or contaminant protection, so if the rack sits in a shared corridor, warehouse, or tenant space, use a lockable enclosed cabinet instead. The top channel on this one is there to carry cable runway and ladder rack overhead, which is the usual open-rack setup in a network bay.

Yes, that is what a network bay rack is for. The top channel style lets multiple frames be joined in a row and tied into a common overhead cable runway, giving you 41 mounting spaces per frame. Each frame still needs its own floor anchorage to hold the Seismic Zone 4 rating.

Finish is Telco gray powder coat over steel, which is the standard color used across Eaton B-Line telecom racks and most carrier-style network bays, so it lines up with existing gray equipment racks and cable runway in a typical MDF or IDF.

Order Eaton B-Line model SB5867090TG. The TG suffix denotes the Telco gray powder coat finish, and the frame ships as a single model with no finish or height options to specify.
