B-Line SB5764084TG Eaton series open frame racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 45 mounting spaces, Top channel style, Seismic Zone 4, network bay closed duct rack, 11 gauge, ASTM A1011SS

It is. The SB5764084TG is built as a Seismic Zone 4 network bay closed duct rack, so it is the version to specify for high seismic regions rather than a standard open frame bay. It is also UL Listed.

114 pounds bare. That is a two-person lift to stand it up, and on a raised floor you should be putting the base over structural support before you load 45U of gear on it.

The SB5764084TG comes in Telco gray powder coat, the standard central-office gray used across the Eaton B-Line open frame rack line, so it lines up visually with existing telco bays. Confirm your existing bays are also 19 inch, 84 inch tall frames if you want a level top channel across the lineup.

A closed duct network bay runs enclosed vertical cable ducts alongside the equipment rails, so patch cords are routed and protected inside the bay rather than hanging on the open uprights. Pick the closed duct version, like the SB5764084TG, for high-density cross-connect and patching work; a plain open frame bay is the simpler choice where you are only mounting a few switches and cable volume is low.

11 gauge steel to ASTM A1011SS, finished in Telco gray powder coat. The heavier 11 gauge material is what lets the bay carry a full 45 spaces of equipment in a seismic application, and the powder coat holds up in an unconditioned MDF or equipment room.

Order by manufacturer part number SB5764084TG from Eaton B-Line. That single number covers the 19 inch by 84 inch, 45 space, Telco gray Seismic Zone 4 closed duct bay; there are no finish or size options to specify on it.
