B-LINE SB212918YZ – Frequently Asked Questions

1) What does a B-Line runway dropout like the SB212918YZ actually do on a cable runway?
The Eaton B-Line SB212918YZ dropout gives cable a smooth radius as it leaves the runway and turns down toward a rack or cabinet. Instead of cable bending over the bare edge of a stringer or rung, it rides the curved steel surface, which keeps the bend radius under control at the exit point. It is an 18 gauge steel drop-out, not a splice or a support member, so it adds no load capacity to the runway itself.
2) What size runway does the 16 inch B-Line dropout fit?
The dropout measures 16 inches across, with a 4 inch height and 4 inch length/depth, so it is sized to span a 16 inch wide runway section at the cable exit. Measure your runway stringer to stringer before ordering; a dropout wider or narrower than the runway will not sit correctly against both rails.
3) Do I need to order separate hardware to mount the B-Line SB212918YZ dropout?
No extra fasteners needed. The kit ships with self-drilling screws, so it mounts straight to the runway stringer without pre-drilling or sourcing hardware. Bring a driver rated for self-drilling screws into 18 gauge steel.
4) Is the B-Line yellow zinc runway dropout suitable for a data center or telecom room, and is it UL Listed?
It is UL Listed and built from ASTM A569 steel with a yellow zinc finish, which is a plated indoor finish typical of equipment rooms, data centers, and telecom closets. The yellow zinc is corrosion protection for dry interior environments, not a coating intended for outdoor or wet exposure.
5) Will a runway dropout work instead of a waterfall or radius drop on my ladder rack?
They do the same job under different names. The B-Line unit is a steel drop-out that carries cable over a curved surface as it exits the runway downward, which is what a waterfall or radius drop does. What matters is matching the 16 inch width to your runway and confirming the mounting face on your stringer suits the included self-drilling screws.
6) What is the exact part number to order this B-Line runway dropout kit?
Order Eaton B-Line part number SB212918YZ. The YZ suffix designates the yellow zinc finish on the ASTM A569 steel.
7) How much does the B-Line SB212918YZ dropout weigh for overhead runway loading?
It weighs 2.7 lb. That is minor against a runway's rated load, but if you are already near capacity on a long unsupported span with heavy cable bundles, count it along with the cable mass at the exit point.
