B-Line Eaton series runway tubular, 119" height, 119" length, 12" width, ASTM A513 grade, Steel, 1008 steel, 11 gauge, Tubular stringer, Computer whit

It is a tubular cable runway stringer, used to build overhead cable runway in communication pathways such as data centers, telecom rooms, and IDF/MDF closets. Stringers are the side rails of the runway; they run the length of the pathway and cross members tie the pair together to form the ladder. Model SB1712CW is finished in computer white.

What you are buying is the tubular stringer itself, one side rail. A working runway needs a second stringer, cross members sized to the 12 inch width, splice or butt kits at every joint, and your choice of overhead support, wall angle, or triangular support bracket. Order those separately.

Steel, specifically 1008 low carbon steel in 11 gauge tube built to ASTM A513. One stringer weighs 23.1 lb, so a single installer can handle a length, though a 119 inch piece overhead is a two-person lift in practice. Use the 23.1 lb figure per stringer when you total the load for threaded rod and ceiling anchors.

The stringer is UL Classified. Treat the runway as a metallic pathway that still needs to be bonded per your electrical inspector's requirements, using grounding kits and jumpers across the splices.

Tubular stringer has a closed tube profile rather than an open channel section. The closed profile gives a cleaner finished look in exposed data center and telecom rooms and no open channel to collect dust or debris. Open channel runway is more often chosen where you want to drop hardware into the channel. This B-Line piece is the tubular type, 11 gauge, in computer white to match white-finished rack rooms.
