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

The rack is built as a Seismic Zone 4 network bay closed duct rack, and it is UL Listed. The frame is ASTM A570 grade 33 steel, which is what gives it the stiffness for the seismic rating. Anchoring to the slab and any overhead bracing still has to follow the engineer's detail for your building.

This one is an open frame rack, so there is no enclosure, no doors, and no locking. That is what you want in a secured telecom room where airflow and cable access matter more than physical security. If the equipment sits in a shared or public space, or you need lockable access and a controlled airflow path, choose a floor-standing enclosure cabinet instead of an open bay.

The top channel gives you a structural channel across the head of the rack, which is where overhead ladder rack or cable runway gets tied in and where the closed duct section carries cable down the bay. It is the arrangement telco and network bays are usually built with when cable comes in from above rather than under a raised floor.

The rack weighs 81.71 lb bare, and at 90 inches tall it is an awkward two-person lift to stand up and hold plumb while the base is anchored. Plan the anchor layout before you tip it upright, especially on a seismic install.

Finish is Telco gray powder coat over steel, not wet paint, so it holds up to equipment being slid in and out of the bay. Telco gray is the standard shade for central office and network bays, so it matches existing runs of B-Line frames in the same room.
