B-Line Eaton series open racks, Steel, Yellow zinc, 12-24 panel mounting holes, 44 mounting spaces, Top angle style, Seiemic zone 4, network bay open

The SB5762138YZ gives you 44 mounting spaces of usable equipment room, which is 44U of panel space on a 19 inch wide rack. Plan your switch, patch panel and cable manager stack against that 44U figure before ordering.

Yes. The rack is a 19 inch EIA-style frame and the rails are punched with 12-24 panel mounting holes, so any 19 inch rack-mount panel, switch or shelf drilled for 12-24 hardware mounts directly. If your gear was supplied with 10-32 or M6 cage-nut hardware, you will need 12-24 screws instead.

The SB5762138YZ is built as a seismic zone 4 network bay open duct rack, so it is the version specified where zone 4 anchorage is called out on the drawing. It is also UL Listed. Seismic performance still depends on anchoring the base to the slab per the structural detail for your site.

It is 19 inches wide, with a stated height of 138 inches and a length/depth of 138 inches, and it weighs 130 lb. At that height and weight this is a two-person set, and you want to confirm your ceiling and cable tray clearance before it goes in.

An open frame rack such as the B-Line network bay open duct rack leaves all four sides accessible, which is what you want in a locked telecom room where patch density and moves/adds/changes matter more than physical security. If the equipment sits in a shared or public space, or you need airflow containment and lockable doors, an enclosed cabinet is the better call. This one has no doors or side panels.

Order Eaton B-Line model SB5762138YZ. That is the yellow zinc, 44 mounting space, 12-24 drilled, top angle configuration. Mounting screws, cable managers and any floor anchors are separate line items.

The frame is steel with a yellow zinc surface finish, a plated corrosion-resistant coating rather than paint. It suits conditioned indoor telecom and equipment rooms. For wet, washdown or exterior environments you would want a different finish specification.

The rack is fabricated from ASTM A1011SS steel, which is the structural-quality hot-rolled sheet grade named on the submittal. If your drawing calls for an ASTM A1011 structural sheet frame, this meets that material callout.

Top angle refers to the angle member across the top of the frame, which is what you use to land overhead ladder rack or cable runway and tie the bay into the room's cable pathway. If you are bracing to structure or running duct overhead, that top angle is your attachment point.
