B-Line SB5771096YZ Eaton series open frame racks, Steel, Yellow zinc, 12-24 panel mounting holes, 51 mounting spaces, Top angle style, Seismic Zone 4, network bay closed duct rack

The SB5771096YZ gives you 51 mounting spaces on a 96 inch tall frame, with 12-24 tapped panel mounting holes on the rails. That is 51 rack units of usable mounting height for switches, patch panels, and rack-mount servers, and the 12-24 thread means you mount gear directly with 12-24 screws instead of adding cage nuts.

Yes. The SB5771096YZ is a 19 inch wide frame, which is the standard EIA panel width that network switches, patch panels, and rack-mount servers are built to. Equipment with standard 19 inch mounting flanges bolts straight to the rails using 12-24 hardware.

It is. The SB5771096YZ is built as a Seismic Zone 4 network bay closed duct rack, so it is the frame to specify for California hospital, data center, and institutional work where the structural engineer is calling out zone 4 anchorage. It is also UL Listed.

Closed duct construction means the vertical channels are enclosed, so cable runs drop inside the bay uprights rather than hanging on the outside of the frame. The top angle style gives you a flat run across the head of the rack for anchoring to overhead ladder rack or bracing, which is how these frames tie into a seismic bracing scheme.

The frame weighs 121 lb on its own. That is a two-person lift to stand a 96 inch bay upright, and it is the empty weight only, before any equipment loading, so size your floor anchors and seismic hardware off the loaded total rather than the 121 lb.

No cage nuts. The rails on the SB5771096YZ are drilled and tapped 12-24, so you mount panels with 12-24 machine screws straight into the rail. If your equipment shipped with square-hole cage nut hardware, order 12-24 screws and washers instead.

An open frame bay like the SB5771096YZ gives all-around access to cabling and airflow with no doors to swing, which is why it is the standard choice for MDF and IDF rooms, patch fields, and switch stacks in a secured space. Choose an enclosed cabinet instead when you need lockable physical security, dust control, or a contained hot aisle. This frame is a 19 inch, 51 space, 96 inch tall open bay.

The frame is steel with a yellow zinc plated finish. Yellow zinc is a plated corrosion-resistant coating rather than paint, so it holds up in indoor telecom and MDF rooms, including ones that are not tightly climate controlled. It is not a powder-coated cosmetic black finish, so if the rack sits in a visible lobby or office space, expect the plated look.

Order it as B-Line SB5771096YZ, from the Eaton B-Line open frame rack series. The YZ on the end is the yellow zinc finish and the 96 in the number matches the 96 inch frame height.
