B-Line Eaton series runway tubular with removable post, 119" height, 119" length, 24" width, ASTM A513 grade, Steel, 1008 steel, 11 gauge, Tubular str

The Eaton B-Line SB1824AYZ is a tubular stringer section for cable runway in communication pathways, the overhead ladder-style tray that carries copper and fiber between racks in a data center or telecom room. Stringers are the side rails of that runway; they run the length of the pathway and the cross members tie between them. This one is a 24 inch width runway component with a removable post.

What you are buying is the tubular stringer itself, the runway side rail with its removable post. Cross members, splice kits, wall angle, threaded rod, and junction hardware are separate items sized to the same 24 inch pathway width, so list them on the order alongside the stringers to finish the run.

Steel, specifically 1008 steel at 11 gauge, manufactured to ASTM A513 tubing. The finish is yellow zinc. That is a plated indoor finish, appropriate for equipment rooms and data centers rather than exposed exterior runs.

It is UL Classified. That is the rating carried on the SB1824AYZ; for grounding and bonding of the runway itself, follow your spec and use the manufacturer's bonding hardware, since the classification does not by itself substitute for a bonding conductor.

31.7 lb per section. That is a two-person lift at height when you factor in the 119 inch length, and it matters when you are sizing threaded rod, ceiling anchors, or wall angle support spacing for a loaded runway.

Order Eaton B-Line part number SB1824AYZ. It is a single configuration, so there is no finish or length option to specify separately: 24 inch width, 119 inch section, 11 gauge steel, yellow zinc, with a removable post.
