B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 66 mounting spaces, Top channel style, Seismic Zone 4, ope

Yes. The Eaton B-Line SB5857138TG is built as a Seismic Zone 4, open duct unequal flange rack, so it is intended for the highest seismic design category work where the structural engineer calls for zone 4 rated equipment racks. It is also UL Listed. Anchoring to the slab and any required overhead bracing still has to follow the job's seismic detail.

The rails are punched for 12-24 panel mounting holes, which is the common tapped telecom and network rack thread. Equipment with 12-24 mounting screws goes straight on. If your gear ships with 10-32 or cage nut hardware, you will need to change screws or use an adapter, since these rails are 12-24.

It gives 66 mounting spaces of usable rail. At the standard 1.75 inch per rack unit, that is a full-height frame for switches, patch panels and rack-mount UPS in a telecom or MDF room. Plan your panel and cable manager stack against that 66 space count before ordering.

Published figures are 138 in height, 138 in length/depth and 23 in width, with a product weight of 107.13 lb. The 23 inch width is the footprint dimension to lay out against wall clearances and hot/cold aisle spacing; the weight is bare frame only, before any equipment load.

An open frame rack such as the B-Line SB5857138TG is for secured telecom and equipment rooms where the room itself provides the physical security and the techs want all four sides of the gear accessible for patching and cable dressing. Go to an enclosed cabinet instead when the rack sits in a shared or public space, needs lockable doors, or needs contained airflow. This one is an open duct unequal flange design, so cabling runs in the open along the frame.

The SB5857138TG is a top channel style frame, which is the configuration used to bond and brace the rack to overhead cable runway rather than leaving it free standing. The runway, brackets and threaded rod for that connection are separate items and are not part of the rack itself.

Steel construction with a Telco gray powder coat, which is the standard shade used across telecom and central office frames, so it will line up visually with existing telco gray racks and ladder rack. Top channel style frame.
