B-Line Eaton series open racks, Steel, Yellow zinc, 12-24 panel mounting holes, 43 mounting spaces, Seismic Zone 4, open duct unequal flange rack, 11

Yes. The SB5762090YZ is a 19 inch wide open frame rack with 43 mounting spaces, so it takes standard 19 inch EIA rack-mount panels, patch panels and switches. Rack units are counted in 1-3/4 inch increments, so 43 spaces covers a full-height equipment stack on a 90 inch tall frame.

The rails are punched with 12-24 panel mounting holes, the tapped-rail pattern common on North American open frame racks. Equipment mounts directly with 12-24 rack screws, so no cage nuts are needed, but the screws themselves are a separate item from the rack frame.

It is built as a Seismic Zone 4 rack, the highest zone classification, which is what specifiers call out for California and other high-seismic jurisdictions. The frame is 11 gauge ASTM A1011SS steel and it is UL Listed. Floor anchorage to the structural slab per the project's seismic detail is still the installer's responsibility.

Plan for a 19 inch wide by 90 inch deep footprint at 90 inches tall. It weighs 117 lb bare, before any equipment, so figure floor loading and anchoring for that plus your gear. Add front and rear service clearance per your local electrical code and the equipment maker's airflow requirements.

An open frame rack such as the SB5762090YZ gives you access from all four sides and unrestricted airflow, which suits a locked telecom or IT room where the room itself provides the security. Choose an enclosed cabinet instead when the equipment sits in a shared or public space and needs physical lockdown, or when you need dust and contaminant control. This one is an open duct unequal flange rack, so there is no door, side panel or top.

Unequal flange means the two legs of the rack upright are different widths, giving a deeper mounting flange on one side. That extra flange depth is what carries cable management and duct hardware alongside the equipment, which is why it is paired with the open duct design on the SB5762090YZ. If you are running heavy horizontal and vertical cable loads up the frame, that is the reason to pick this profile over a plain equal-flange channel rack.

The frame is 11 gauge ASTM A1011SS structural steel, which is the heavier of the two common open-rack gauges and is what B-Line uses on its seismic-rated frames. It supports a full 43 spaces of loaded equipment. For heavy bottom-mounted items like a UPS, keep the weight low in the frame and follow your seismic anchorage detail.

Order B-Line part number SB5762090YZ. It is one fixed configuration: 90 inches tall, 19 inches wide, 12-24 tapped rails, 43 spaces, yellow zinc. There is no finish or height option to select on this model, so if you need black or a shorter frame that is a different B-Line part number.

Yellow zinc is a plated, corrosion-resistant finish over the steel, used on electrical support hardware for indoor and protected environments. It is not a coating rated for direct weather exposure, so keep the rack in a conditioned or at least covered space. The finish is also conductive, which matters if you are bonding the frame into your grounding system.
