B-LINE SB2129U15FB – Frequently Asked Questions
1) Is the B-Line 15 inch runway dropout UL Listed?
Yes, the SB2129U15FB steel runway drop-out is UL Listed. That is usually the box an institutional or MRO spec needs checked for telecom pathway hardware.
2) What does a runway dropout actually do in a data center cable run?
It gives the cable a smooth radius where it leaves the runway and turns down to a rack or cabinet, so the copper or fiber is not bent over a bare steel edge. The SB2129U15FB also has cable tie down holes so you can strain-relieve the bundle right at the transition instead of letting the weight hang on the cable.
3) What is the B-Line runway dropout made of, and will the finish match black runway?
A569 steel at 18 gauge with a flat black powder coat, so it matches standard flat black B-Line runway and ladder rack rather than a gray or zinc finish.
4) Is the B-Line runway dropout a complete kit or do I need extra hardware?
It ships as a runway dropout kit, and the tie down holes for securing cable bundles are already punched in the part. No separate drilling is needed for the tie points.
5) How much does the SB2129U15FB dropout weigh for overhead runway loading?
2.2 pounds. Light enough that adding several drop-outs along a run adds little to the runway's supported load, and one installer can set it in place overhead without help.
