B-Line Eaton series open racks, 11 Gauge steel, 1/2"-13 Rack attachment hardware, Telco gray powder coat finish, Extender - network bay

It's an open frame rack extender in the Eaton B-Line series, built as a network bay section that widens an existing open rack run rather than standing alone as a full four-post enclosure. Fabricated from 11 gauge steel with a Telco gray powder coat finish, it uses 1/2"-13 rack attachment hardware to tie into the adjacent frame. Overall it measures 56 in high, 25.5 in wide, 5 in deep and weighs 57.8 lb.

It mounts with 1/2"-13 rack attachment hardware, so the existing frame has to be drilled and tapped for 1/2"-13 at the mating points, which is the standard Eaton B-Line open rack attachment thread. If your in-place rack uses a different attachment thread or a different bay pattern, the extender will not pick up the holes. Confirm the 1/2"-13 prep on your rack uprights before ordering.

An extender like the SB5946056TG adds a bay to a run you already have standing, sharing the adjacent upright, and at 5 in of frame depth it is a widening section rather than a freestanding rack. Choose it when you are expanding an existing B-Line lineup and can bolt into the in-place frame with 1/2"-13 hardware. If the new position is isolated, in a different room, or you need full four-post equipment mounting depth, order a complete open frame rack instead.

Plan for a 56 in tall, 25.5 in wide footprint with a 5 in depth on the extender section itself. That 5 in depth is the extender frame, not a full cabinet depth, so your cable and equipment depth still comes from the rack it attaches to. The 25.5 in width is what you add to the existing run, so measure your aisle clearance from the current rack face outward before committing.

The extender ships in Telco gray powder coat, which is the standard finish across the Eaton B-Line open rack line, so it lines up with existing B-Line gray frames in the same room. If your installed racks are black, this section will not match visually, and finish is not something to field paint on a bonded rack without redoing the grounding path.

Order it as Eaton B-Line SB5946056TG. That single part number covers the 56 in, 25.5 in wide, 11 gauge steel network bay extender in Telco gray powder coat with 1/2"-13 rack attachment hardware, so there is no separate finish or gauge suffix to specify.

No certification applies to the SB5946056TG extender, so do not list one on a submittal. It's a steel structural bay section, and any listing requirements on your job will attach to the active equipment, bonding and grounding components rather than to the frame extension itself.
