B-Line Eaton series runway tubular, 119" height, 119" length, 18" width, ASTM A513 grade, 1008 steel, 11 gauge, Tubular stringer, Computer white

It's a cable runway stringer, the side rail that carries cable pathway above racks and cabinets in communication rooms. Eaton B-Line lists the application as cable runway in communication pathways. Stringers are the structural rails; cross members, splice kits, and wall or ceiling supports make up the rest of the runway system and are ordered separately.

This is one stringer, meaning one side rail, not a complete ladder rack. A finished runway takes two stringers plus cross members at the spacing you want, so plan on ordering the stringers in pairs and adding the rungs, splice hardware, and supports to complete the pathway.

Formed from 1008 steel to ASTM A513 tubing, 11 gauge wall, finished in computer white. The A513 designation is the mechanical tubing standard the stringer is built to, which is what a spec engineer is usually looking for on the drawing.

27.4 lb per section. That figure matters when you're sizing threaded rod, ceiling anchors, or wall angle support spacing, since the hanger load is the stringer weight plus cable fill, not the stringer alone.

Yes, the tubular stringer is UL Classified. For data center and telecom rooms where the inspector wants listed pathway components, that's the line on the submittal.

Computer white is B-Line's standard runway color, so this section matches existing white B-Line cable runway on the same job. If your room was built out in black, the finish won't match and you'd want the black version of the same stringer instead.
