B-LINE SB2129U09TG – Frequently Asked Questions
1) What is a B-Line runway dropout kit used for in a cable runway?
The Eaton B-Line SB2129U09TG dropout is the curved piece that lets cable leave the runway and turn down toward a rack or cabinet without a sharp bend. It provides a radius for cable exiting the runway, so the bend radius of the jacket is protected at the exit point instead of the cable rolling over a bare steel edge.
2) Do I need to order separate hardware to mount the B-Line runway dropout?
No extra fasteners needed. The kit ships with self-drilling screws, so it attaches to the runway stringer without drilling and tapping first. Bring a driver rated for self-drilling screws into 18 gauge steel.
3) Is the Eaton B-Line SB2129U09TG dropout UL Listed?
Yes, the SB2129U09TG runway dropout is UL Listed. That is the relevant point for an inspector or a spec that calls for listed runway components in a telecom or data room.
4) What material and finish is this runway dropout, and will it match my existing B-Line runway?
It is ASTM A569 steel in 18 gauge with a Telco gray powder coat, which is the standard finish on B-Line ladder runway, so it blends with an existing gray runway run rather than standing out.
5) Is a runway dropout the same thing as a waterfall, or do I need both?
They do the same job at different places. This 9 inch B-Line dropout is the radius piece where cable leaves the runway and drops vertically to a rack or cabinet. If you instead need the radius where cable transitions off the end of a runway run, that is an end waterfall. Order by where the cable actually turns, and match the piece to your runway width.
6) How heavy is the B-Line 9 inch runway dropout for overhead install?
It weighs 1.2 lb, light enough for one tech to hold in place on a ladder while driving the screws. It adds effectively nothing to the load on threaded rod or wall angle supporting the runway.
7) What part number do I order for the B-Line 9 inch runway dropout kit?
Order Eaton B-Line SB2129U09TG. That single model covers the 9 inch steel dropout in Telco gray with the self-drilling screws included.
