B-Line SB5872096TG 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 open duct rack, ASTM A1011SS

Yes, the SB5872096TG is built as a Seismic Zone 4 network bay open duct rack, and it is UL Listed. That is the reason to choose it over a general purpose two-post rack in California, Alaska or any jurisdiction enforcing Zone 4 anchorage for telecom frames.

The rails on the SB5872096TG are tapped 12-24, so no cage nuts are needed. Plan on 12-24 rack screws for each piece of equipment you mount; if your gear came with 10-32 hardware it will not thread into these rails.

Top channel means the rack is made to tie into an overhead channel and cable runway rather than stand alone. In a network bay lineup, multiple frames are joined and braced through that top channel, which is also part of how the Zone 4 seismic load path works. Budget for the overhead runway and bracing as separate line items.

An open duct rack such as the SB5872096TG gives you access from all sides and the cheapest path for cable, and it suits a secured telecom room where the door is the access control. Go to an enclosed cabinet instead when the gear sits in a shared or public space, when you need locking security per bay, or when you have to duct and filter airflow. The open frame has no doors, sides or fan provision.

45 mounting spaces on the 96 inch frame means 45 rack units of gear, counting each 1U device as one space. A 48 port 1U patch panel plus a 1U switch takes two, so a typical closet build of panels, switches and a UPS leaves plenty of room. Reserve a few spaces for horizontal cable management.

Steel to ASTM A1011SS, finished in Telco gray powder coat. Powder coat over steel is the standard for indoor telecom frames, and the Telco gray matches the common equipment and runway color so it blends into an existing lineup.

SB5872096TG is a single configuration: 19 inch wide, 96 inch tall, 45 spaces, 12-24 tapped rails, Telco gray. There is no finish or height choice to specify when ordering it, so order by that part number exactly.
