B-Line Eaton series runway tubular, 119" height, 119" length, 30" width, ASTM A513 grade, Steel, 1008 steel, 11 gauge, Tubular stringer, Yellow zinc

The SB1730YZ is a tubular stringer for overhead cable runway in communication pathways, the ladder-style tray that carries copper and fiber above racks in a data center or telecom room. A runway section is built from two stringers plus cross members; the stringer is the side rail, not a complete runway assembly.

No. Ordering SB1730YZ gets you the tubular stringer itself. Splice plates, junction kits, wall angle or ceiling support hardware, cross members, and grounding hardware are separate line items, so plan them into the takeoff.

Yellow zinc plated 1008 steel is an indoor finish. It suits conditioned telecom and data rooms; for exterior runs or wash-down areas you want a hot dip galvanized or stainless product instead.

Tubing is made to ASTM A513 in 1008 steel at 11 gauge. If your drawing calls out A513 tubular runway stringers, this meets that callout.

Each piece weighs 36.1 lb. Add that to your cable fill and hardware when sizing threaded rod, ceiling anchors, or wall angle support for the run.

Tubular stringers like the SB1730YZ use closed tube sections rather than open channel, which gives a cleaner appearance in exposed data center and telecom rooms where the runway is visible. Open channel ladder rack is the more common choice where the run is hidden above a dropped ceiling or where you are matching existing channel-style runway already in the building.
