B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 65 mounting spaces, Top channel style, Seismic Zone 4, net

The SB5776090TG gives you 65 mounting spaces on a 90 inch tall frame, so a full stack of switches, patch panels and rack-mount servers goes on one upright without a second rack. Rails are punched 12-24, which is the thread most telecom panels and shelves ship with.

No cage nuts needed. The rails come punched with 12-24 panel mounting holes, so you thread 12-24 screws straight into the rail. If your equipment shipped with 10-32 hardware, you will need 12-24 screws instead.

Yes. The SB5776090TG is built as a Seismic Zone 4 network bay open duct rack, which is the rating specified for California and other high seismic regions. It is also UL Listed.

Plan on a footprint from a 23 inch wide frame with a 90 inch length/depth dimension, standing 90 inches tall. At 90 inches of height you also want to check ceiling clearance and door heights on the route in, plus overhead room for cable tray or ladder rack landing on the top channel.

Top channel means the rack is finished with a channel across the top of the uprights, which is what overhead cable runway or ladder rack attaches to. For a network bay open duct rack like this, cable enters from above through the runway and drops into the vertical duct rather than running through a closed cabinet, so it is the right choice where you are building a row of bays fed by overhead tray.

An open rack gives you access from all four sides, easier cable dressing and no fan or ventilation planning, which is why it is standard in locked telecom and MDF rooms. Go with an enclosed cabinet instead when the equipment sits in a space you cannot secure, needs dust protection, or has to be locked for compliance. The SB5776090TG is the open frame option, steel with a Telco gray powder coat finish.

The finish is Telco gray powder coat on steel, the standard shade used across telecom bays, so it lines up visually with existing Telco gray equipment racks and runway. Colour matching across brands is never exact, but it is the same industry finish name.

The frame weighs 121 lb on its own, so it is a two-person lift and stand. Add a seismic Zone 4 install and you are anchoring to the slab, which means laying out and drilling floor anchors before the frame goes vertical.
