B-Line Eaton series open racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 49 mounting spaces, Top channel style, Seismic Zone 4, clo

The rails are punched with 12-24 panel mounting holes, so any panel or chassis you already screw down with 12-24 hardware mounts directly, no tapping or clip nuts needed. There are 49 mounting spaces on the rack. Mounting screws are not part of the rack itself, so order 12-24 rack screws separately if you don't have them on hand.

Yes. The SB5768138TG is built as a Seismic Zone 4 closed duct unequal flange rack, which is the configuration specified for the highest seismic zone on telecom and data room drawings. It is also UL Listed. Seismic anchorage to the floor and any overhead bracing still has to follow the engineer's detail for your building.

Unequal flange means the two flanges of the upright are different widths, which gives you a deeper mounting surface on one side for equipment and a narrower side for cable and duct routing. Closed duct means the upright forms an enclosed channel that vertical cable runs sit inside of, instead of being strapped to an open web. That is the configuration telecom specs call for when vertical cable management has to be inside the frame and the rack is being anchored for Seismic Zone 4. An equal flange or open channel upright is the simpler choice when cable is managed with separate bolt-on vertical managers.

It weighs 136 pounds bare, before any equipment. At 138 inches tall that is a two-person lift minimum, and most crews stand it with three: two on the frame and one setting the floor anchors. Plan on the anchors being drilled and set before you tip it up.

Yes, it is a top channel style frame, so the top of the uprights is tied together with a channel you can land cable runway and overhead bracing on. Runway, butt splice kits and any auxiliary framing channel are separate items and need to be ordered with the rack if the run isn't already in place.

Order Eaton B-Line model SB5768138TG. That single number covers the 138 inch, 23 inch wide, Telco gray, 12-24 punched, 49-space Seismic Zone 4 closed duct unequal flange rack, so there are no finish or hole-pattern options to specify on top of it.

The finish is Telco gray powder coat, the standard color used across telecom and central office frames, so it lines up visually with existing Telco gray racks and ladder rack in the same room. Powder coat rather than paint also means it holds up to gear being slid in and out of the bays.
