B-Line Eaton series runway tubular with removable post, 7" height, 119" length, 24" width, Steel, ASTM A513 steel tube, Tubular stringer trough, Flat

Steel construction, specifically ASTM A513 steel tube stringers, finished in flat black powder coat. The black finish is what most integrators run overhead in customer-facing equipment rooms where the runway is visible.

Each 119 inch section weighs 34 lb bare. Size your threaded rod, ceiling anchors and wall angle supports for that plus the cable load you intend to carry, which on a loaded run is usually the larger number by far.

This is a tubular stringer trough, meaning the side rails are closed steel tube rather than open flat bar or channel. Tube stringers give a cleaner finished look overhead and no sharp open channel edge to dress cable against. Flat or channel stringer runway is the other common style and typically accepts a wider variety of clamp-on accessories that bite onto an open profile. If your existing runs are channel stringer, match the stringer style so splice kits and butt splices line up.

What you are buying is the runway section itself, 24 inches wide by 119 inches long with a removable post. Ceiling kits, threaded rod, wall angle brackets, butt splice kits and elbows are separate items and need to be ordered for the run you are building.

The SB1824AFB gives a 24 inch usable width with a 7 inch stringer height, which is the common mid-size for rack-to-rack backbone and horizontal bundles in a telecom room. If you are feeding a long row of racks or expect growth, step up to a wider runway rather than running two narrow sections side by side.
