B-Line Eaton series open racks, Steel, Telco gray powder coat, 39 mounting spaces, Top channel style, Seismic Zone 4, network bay open duct rack, 14

The SB5872084TG is an 84 inch tall open frame rack with 39 mounting spaces, so you get 39 usable EIA rack units for switches, patch panels and rack-mount servers. It is 19 inches wide, matching standard 19 inch rack-mount equipment.

Yes. The SB5872084TG is built as a Seismic Zone 4 network bay open duct rack, which is the configuration specified for the highest seismic zone. It is 14 gauge steel to ASTM A569, and it is UL Listed. Anchoring to the slab and any overhead bracing still has to follow your project's seismic detail.

Finish is Telco gray powder coat over steel, which is the standard telecom room gray, so it lines up visually with existing B-Line and other telco-gray bays. Style is top channel, so plan for that at the top of the frame when you tie in ladder rack or runway.

The top channel runs across the top of the 84 inch frame and gives you a rigid point to attach overhead cable runway or ladder rack and to tie bays together in a row. On an open duct network bay like this one, that overhead connection is how the rack picks up lateral support in a seismic install.

Open frame. The SB5872084TG is a network bay open duct rack, so equipment is accessible from all sides and there is no lockable enclosure. If the room is shared or unsecured and you need controlled access to the gear, an enclosed cabinet is the right choice instead. Open frames are used where the room itself is secured and airflow and cable access matter more.

The frame is 14 gauge steel meeting ASTM A569, which is the hot-rolled carbon steel sheet spec, and it is UL Listed. That is the heavier structural build used for seismic-rated bays rather than light-duty relay racks.

Shipping weight is 111.67 lb for the frame, so two people can stand it up and walk it into place. It is an open frame, not an enclosure, so there are no doors or side panels adding weight once it is positioned.

Published dimensions are 84 inches height, 84 inches length/depth and 19 inches width. Lay the bay out on that basis and add your own service clearance front and rear for cable dressing and equipment access.
