B-Line Eaton series open racks, Double sided, Steel, Telco gray powder coat, 12-24 panel mounting holes, 39 mounting spaces, Top channel style, Seism

It is built as a Seismic Zone 4 closed duct unequal flange rack, so it is the version specified for the highest seismic zone rather than a standard commercial frame. It is UL Listed. Anchoring to the slab and any overhead bracing still has to follow the engineer's detail for the room.

84 inches tall, 23 inches wide, and 84 inches on the length/depth dimension. It weighs 78.53 lb bare, so two people can stand it up, but plan the aisle clearance around the 84 inch footprint dimension before you set anchors.

Double sided means the frame carries mounting rails usable from both faces, so you can load equipment or patch panels front and back instead of from one side only. There are no doors or side panels on an open frame rack, so cabling and airflow are unrestricted.

Yes, it is a top channel style frame, so the top of the rack is set up to take runway or ladder rack attachment and overhead bracing rather than being an open capped upright.

An open frame rack such as the SB5859084TG has no doors or side panels, which makes cabling and access easier from both faces and keeps airflow unrestricted. Choose an enclosed cabinet instead if you need physical security, dust control, or lockable access for the equipment. For a controlled telecom or MDF room where techs need constant access, the open frame is the usual call.

The frame is ASTM A570 grade 33 steel with a Telco gray powder coat, which is the standard finish used to match existing telco equipment racks and ladder rack in a central office or MDF room.
