B-Line Eaton series open racks, Double sided, Steel, Telco gray powder coat, 12-24 panel mounting holes, 50 mounting spaces, Top angle style, Seismic

Yes. Eaton B-Line model SB5864108TG is built as a Seismic Zone 4 network bay closed duct rack, fabricated from ASTM A570 grade 33 steel, and it is UL Listed. That is the spec to cite when a drawing calls for seismic-rated open frame racking in a zone 4 location.

The frame stands 108 in tall and gives you 50 mounting spaces, which is enough for a full switch and patch stack in a network bay without stepping up to a second frame. Rail holes are 12-24 tapped panel mounting holes, so panels and shelves need 12-24 screws rather than 10-32.

12-24. The mounting rails on the SB5864108TG are tapped with 12-24 panel mounting holes, so order 12-24 rack screws and any cage-free hardware to match. 10-32 screws will not thread into these rails.

Open frame. The SB5864108TG is part of the Eaton B-Line series open frame racks, so there are no side panels, no doors, and no lockable enclosure. If you need physical security on the gear or forced-air containment, you want a cabinet instead; if you want open access and cable management from all sides in a controlled telecom room, this is the right form.

Plan around 19 in width and 108 in for the length/depth dimension, with a height of 108 in. Take that 108 in depth figure seriously when laying out a room, because it is well beyond a typical two-post frame footprint and will drive your aisle clearances.

Double sided means equipment mounts from both faces of the bay rather than a single front rail set, which is how network bays are typically built up when you want patch fields on one side and active gear on the other. It ships in a top angle style, so the top is finished with an angle member for supporting cable runway and ladder rack above the bay.

Product weight is 131.89 lb for the frame itself, before any equipment load. That is a two-person set, and since it is a Seismic Zone 4 bay the base has to be anchored to the slab per your structural detail, not free-standing on the finished floor.

Finish is Telco gray powder coat over steel, which is the standard color for central office and telecom bay hardware, so it lines up visually with existing Telco gray runway, bays, and ladder rack. If your room is standardized on black, this is the wrong finish to add to it.
