B-Line Eaton series open racks, Steel, Yellow zinc, 12-24 panel mounting holes, 48 mounting spaces, Top angle style, Seismic Zone 4, network bay open

Yes. The SB5768084YZ is built as a Seismic Zone 4 network bay open duct rack, so it is the version to specify where a project's structural requirements call for Zone 4 anchoring. It is also UL Listed.

48 mounting spaces on an 84 inch tall frame. That is the usable panel capacity for switches, patch panels and rack-mount gear; plan your equipment list against 48 spaces, not the raw 84 inch height, since the top angle and base take up frame length.

The mounting rails are tapped with 12-24 panel mounting holes, which is the common threaded pattern for rack-mount network gear, so panels and switches with 12-24 hardware thread directly in. No cage nuts are needed. If your equipment came with 10-32 or M6 screws, order 12-24 rack screws to match.

The frame measures 23 in wide, 84 in deep by the published length/depth figure, and 84 in high. It weighs 118 lb bare, before any equipment load. Since it is an open frame with no side panels or doors, you also need working clearance front and rear for cable dressing and terminations.

The frame is ASTM A570 grade 33 steel, which is the material line to cite when a drawing or submittal calls for a structural-grade steel rack. It is also UL Listed, which is typically what an institutional or government submittal is after.

What you get is the open frame itself: a top angle style network bay open duct rack with 48 mounting spaces and 12-24 tapped rails. Vertical cable managers, horizontal managers, ladder rack, shelves and rack screws are separate items, so build them into the same order if you are terminating a full bay.

An open frame like the SB5768084YZ gives you all-around access for cabling and passive airflow, with no door or side panels, which is why it is the standard choice in a locked telecom closet where the room itself provides the security. If the rack sits in a shared or public space, or you need dust control, lockable front and rear doors, or contained hot-aisle airflow, use an enclosed cabinet instead. The open frame cannot be retrofitted into a secure enclosure.

Yellow zinc is a plated corrosion-resistant finish over the steel frame, common on structural rack and strut hardware and fine for conditioned indoor telecom and equipment rooms. It is a functional finish rather than a cosmetic one, so if the rack sits in a visible lobby or client-facing space, a painted black frame is the better look.
