B-Line Eaton series open racks, 200 lb, Steel, Telco gray powder coat, 12-24 panel mounting holes, 51 mounting spaces, Top channel style, Seismic Zon

The SB5878096TG gives you 51 mounting spaces on a frame that stands 96 inches tall. That is full-height floor-to-ceiling capacity for a network bay, so you can populate patch panels, switches and cable management top to bottom without stacking two shorter frames.

The mounting rails are punched with 12-24 panel mounting holes, which is the standard threaded pattern for rack-mount network gear. Bring 12-24 rack screws and cage nuts are not needed. If your hardware ships with 10-32 screws, they will not thread into these rails.

Yes. The B-Line network bay closed duct rack is built for Seismic Zone 4 service, and it is UL Listed. That is why it is fabricated from 6 gauge steel to ASTM A1011SS rather than lighter formed sheet.

Plan for a frame 23 inches wide and 96 inches tall, with a stated length/depth of 96 inches. It is a floor-mounted open frame, so allow working clearance front and back plus room overhead for the top channel and overhead ladder runway.

An open frame like this B-Line network bay gives you all-around access to patch cords and passive airflow, and it is the normal choice for telecom and MDF rooms where the space itself is secured. Go with an enclosed cabinet instead if the equipment sits in a shared or public area and needs locked doors, or if you need directed front-to-back fan cooling.

The top channel is the structural cap across the head of the frame. It ties the uprights together for the seismic rating and gives you the attachment point for overhead cable runway or ladder rack coming into the bay, so the cable load lands on the channel rather than on your patch panels.

The finish is Telco gray powder coat over steel, which is the standard shade used across telecom and network bay equipment, so it lines up visually with existing gray racks and runway. Powder coat over 6 gauge steel also holds up to handling during buildout better than painted light-gauge frames.

The frame weighs 124.88 lb empty. Two people can handle it, but at 96 inches tall it is awkward to walk upright, so plan to carry it flat and stand it in place once the floor anchors are laid out.
