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

The SB1812AFB is a 12 inch wide runway section. Stringers are sold and installed in pairs joined by the runway width, so ordering this model commits the pathway to a 12 inch tray width for the run. Length of the section is 119 inches.

Tubing is 1008 steel to ASTM A513 at 11 gauge, finished in flat black powder coat. A513 is the mechanical tubing spec, so the stringer is welded tube rather than formed channel, which is why it takes load across a long unsupported span between threaded rod drops.

23.1 lb per section. Add that to your cable fill when you size threaded rod, ceiling anchors, or wall angle brackets for the run.

What the record covers is the tubular stringer itself with a removable post, in 12 inch width and 119 inch length. Splice plates, junction hardware, threaded rod, wall angles, and ceiling kits are separate B-Line runway accessories and need to be ordered alongside it to finish the run.

Tubular stringer runway gives a closed round profile with no sharp channel edges for cable to bear on, and it reads cleaner on exposed overhead runs in a data room. Formed channel ladder rack is the usual pick where you need heavy fill and standard tray fittings. This B-Line section is 11 gauge A513 tube in flat black, sized at 12 inches wide, so it suits light to moderate communication cable pathways rather than power tray duty.

The removable post lets the vertical support be taken off the tubular stringer, so the runway can be dropped in, aligned, and spliced without fighting a fixed leg, then the post reinstalled. Useful over populated racks where you cannot get a one-piece assembly into position.
