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

The SB1730CW is a tubular stringer section for overhead cable runway in communication pathways, the ladder-style tray that carries copper and fiber above racks in a telecom or data room. The stringer is the side rail member; it runs the length of the pathway and the cross members tie the two stringers together into the runway.

If the existing pathway is a 30 inch wide B-Line series runway, yes, the SB1730CW is the matching 30 inch tubular stringer in computer white. If your existing runway is a different width, or uses a channel (non-tubular) stringer profile, the splice pattern and cross member spans will not line up and you want the stringer that matches that width and profile instead.

A stringer alone is not a runway. You are buying one side rail member; a finished run needs a second stringer, the cross members that set the 30 inch width, splice or butt-splice kits at each joint, and the ceiling, wall angle, or rack-top support hardware. Order those separately in the same 30 inch width.

Formed from 1008 steel to ASTM A513 tubing, 11 gauge. ASTM A513 is the spec for welded carbon steel mechanical tubing, which is what gives the tubular stringer its closed box section rather than an open channel.

36.1 lb per stringer section. Two stringers plus cross members and the cable load is what your ceiling anchors or wall angle support carries, so size the drop rod and anchors off the full assembly, not the single piece.

Yes, it carries a UL Classified marking. That is usually what the inspector is looking for when the runway is used as a grounded communications pathway in a telecom room.

A tubular stringer like the SB1730CW is a closed tube section, which gives a clean finished edge on both faces and is what most spec'd telecom rooms call out when the runway is visible below an open ceiling. A channel stringer is an open C profile, lighter and generally used where appearance matters less. The two do not splice to each other, so pick one profile for the whole pathway.

Computer white. If the existing overhead pathway is black or grey, this section will stand out, so for a visible open ceiling install match the finish across the whole run.
