B-Line Eaton series open racks, 200 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 45 mounting spaces, Top channel style, Seismic Zon

The SB5876084TG open frame rack is rated for 200 lb load capacity. That is the figure to design to when you are stacking patch panels, switches and cable management across the frame. The rack itself weighs 117.22 lb, which matters for how you get it to the floor and set it before anchoring.

Yes. The SB5876084TG is built as a Seismic Zone 4 network bay open duct rack, and it is UL Listed. The frame is 6 gauge steel to ASTM A1011SS, which is what gives it the stiffness that seismic bracing schemes rely on. Anchoring and any required overhead bracing still follow the structural drawings for the room.

The rails carry 12-24 panel mounting holes, so equipment mounts with 12-24 screws directly. Square-hole cage nut hardware does not apply here. If your patch panels and shelves came with 10-32 or M6 hardware, order 12-24 screws before install day.

An open duct rack like the SB5876084TG is the choice for a secured telecom or MDF room where you want two-sided access, maximum airflow and easy cable dressing through the top channel. A cabinet is the better call when you need lockable physical security, dust control, or you are placing gear in an open office or warehouse area. This frame gives no enclosure, no doors and no side panels.

The frame ships as the rack itself. Budget separately for floor anchors sized to your slab, 12-24 mounting screws to match the punched rails, vertical and horizontal cable management, and any overhead ladder rack tying into the top channel. In a Seismic Zone 4 room the anchor and bracing package is specified by the structural engineer, not supplied with the rack.

The top channel runs across the head of the frame and is the structural tie that ladder rack and overhead cable runway land on when you bay multiple racks together. It is also what carries the seismic bracing connection in a Zone 4 room. Frame is 6 gauge steel, so the channel takes overhead loading rather than just capping the uprights.

The finish is Telco gray powder coat over steel, the standard color used across B-Line open frame bays, so it lines up with existing telco gray racks and ladder rack in the same room. Powder coat rather than paint means it holds up to cable pulls and handling during buildout.
