B-Line Eaton series open racks, 200 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 41 mounting spaces, Top channel style, Seismic Zon

Yes. The B-Line Eaton SB5854140TG is built as a Seismic Zone 4 network bay closed duct rack, so it is intended for openings and facilities where seismic anchoring of the rack is required. It is also UL Listed. Zone 4 rating applies to the rack itself; the floor anchorage hardware and structural attachment are separate items you need for the install.

The rails are tapped with 12-24 panel mounting holes, so you thread 12-24 rack screws directly into the rail. No cage nuts or square-hole hardware needed, and square-hole (M6 cage nut) accessories will not work on it. If your existing equipment came with 10-32 screws, you'll need 12-24 screws instead.

Load capacity is 200 lb. That is fine for patch panels, fiber enclosures, light switching and cable management on an open frame, but it is not a rack for loading up with multiple deep servers or UPS units. The frame itself weighs 104.39 lb.

Top channel means the frame is finished with a channel across the top of the uprights rather than an open top. It gives you a rigid tie point for bonding overhead cable runway, ladder rack, or the closed duct pathway this bay is built around, and it stiffens the bay when racks are ganged together in a row.

The frame is steel with a telco gray powder coat, which is the standard central-office and MDF color, so it lines up visually with existing telco gray bays and cable runway. Powder coat also means you should scrape or use a paint-piercing washer at your bonding point to get metal-to-metal contact for the ground.
