B-Line Eaton series runway tubular, 119" height, 119" length, 6" width, ASTM A513 grade, Steel, 1008 steel, 11 gauge, Tubular stringer, Computer white

It's a tubular cable runway stringer, used to build cable runway (ladder rack) for communication pathways in data rooms and telecom closets. Stringers are the side rails of the runway; cross members tie a pair of them together to form the ladder. Model SB17T06CW is the 6 inch wide, 119 inch long version in computer white.

No. Model SB17T06CW is the tubular stringer only, one piece. A working runway also needs cross members at the width you want, butt splice kits to join lengths, and wall or ceiling support hardware such as wall angle support kits and threaded rod with hold-down clamps. Order those separately with the stringers.

It is 1008 steel tube manufactured to ASTM A513, in 11 gauge. One stringer weighs 18.7 lb, so a single installer can set a piece and a two-man crew can hang a full section without a lift.

It is finished in computer white, the standard B-Line runway color found in most telecom and data rooms. If your existing racks and runway are white rather than black, this matches. For black installations you would need the black version of the same stringer instead.

Tubular stringers, like this 11 gauge ASTM A513 piece, use a closed tube section that gives a cleaner finished look in exposed data rooms and no sharp open channel edge for cable to bear on. Formed channel runway is the more common utility choice in back-of-house telecom closets. Both carry cable the same way; pick tubular where the run is visible or where you want the smoother edge over the cable bend.
