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

The SB1712YZ is a tubular cable runway stringer, used to build overhead cable runway in communication pathways such as data centers, telecom rooms, and equipment closets. Stringers are the side rails of the runway; they are joined in runs and crossmembers span between a pair of them to carry the cable. It is UL Classified.

No. The SB1712YZ is the stringer only, one tubular side rail. To build a runway you order stringers in pairs plus 12 inch crossmembers, splice or butt-splice kits to join runs, and your chosen support method (wall angle, triangular brackets, or threaded rod with ceiling kits). Plan those separately on the takeoff.

It is 11 gauge, 1008 steel tubing manufactured to ASTM A513, with a yellow zinc finish. The yellow zinc plating suits dry indoor equipment rooms; it is not a finish for exterior or corrosive environments.

A tubular stringer like the SB1712YZ uses closed steel tube for the side rail, which gives a clean finished appearance and consistent stiffness in both directions. Channel or U-shaped stringers have an open profile that lets hardware be dropped in from the side. Pick tubular where you want the finished look and the standard welded crossmember runway; pick channel where you plan to add or move attachment hardware along the rail frequently. Mixing the two types in one run is not practical because the splice and crossmember hardware differs.
