Yes. The SB5779084TG is built as a Seismic Zone 4 network bay closed duct rack, so it is the version to specify where the structural drawings call for Zone 4 anchorage. It is also UL Listed. Note that seismic performance depends on anchoring the base to the slab per the engineer's detail; the rack itself is the Zone 4 rated frame.

The rails are punched with 12-24 panel mounting holes, which is the standard Telco threaded pattern for rack-mount panels and network gear. If your equipment ships with 12-24 rack screws you can mount directly with no adapter. Gear supplied with 10-32 or M6 cage nut hardware will need its own screws to match the 12-24 thread.

The frame is listed at 84 in height, 23 in width, 84 in length/depth, and 118 lb. Use the 23 inch width for aisle spacing and the 84 inch height to confirm ceiling and overhead ladder rack clearance. At 118 lb bare, one person should not be walking it upright into position alone.

Open frame. The SB5779084TG is an open two-post style network bay rack, not a four-sided enclosure, so there are no doors, side panels, or lockable access. Choose it where you need front and rear hand access to patch panels and terminations. If the room requires physical security or forced-air containment, an enclosed cabinet is the right product instead.

75 mounting spaces on the SB5779084TG frame, which is the usable panel area over the 84 inch height. In practical terms that is 75 single-space positions, so 25 three-space panels or any mix that adds to 75. Plan for some of that being consumed by vertical cable management brackets and power strips if you mount them in the rail rather than beside it.

Top channel means the rack is capped with a channel across the top uprights rather than open rail ends. That channel is what you use to tie the rack into an overhead ladder rack or runway and to brace the top of the frame, which matters on a Seismic Zone 4 install where the top of the rack usually gets restrained as well as the base.

It is a network bay rack in Telco gray with the standard 12-24 hole pattern and a top channel, which is the configuration used to gang bays into a continuous lineup with joining kits and shared overhead runway. Confirm your existing bays are the same 84 inch height so the top channels and any horizontal cable management land at the same elevation.

Order Eaton B-Line MPN SB5779084TG. That single number covers the 84 inch, Telco gray, 12-24 punched, 75 space Seismic Zone 4 closed duct network bay, so there are no finish or height options to specify with it.

Steel construction, specified as ASTM A1011SS steel, with a Telco gray powder coat finish. Telco gray is the common carrier and central office color, so it matches existing bays and cable runway in most telecom rooms. Powder coat holds up better than wet paint against scuffing from equipment being slid in and out.
