B-LINE SB2129U09YZ – Frequently Asked Questions

1) What does the B-Line SB2129U09YZ runway dropout actually do on a cable runway?
It gives cable a controlled radius where it leaves the runway and drops down to a rack or cabinet. Instead of copper or fiber bending over a bare steel rail edge, the formed steel dropout carries the bend so the cable keeps a gentle curve on the way out. It is a 9 inch steel runway drop-out in yellow zinc.
2) Does the B-Line dropout kit come with the fasteners, or do I need to order hardware separately?
Self-drilling screws are included with the kit, so it mounts to the runway stringer without pre-drilling and without a separate hardware order.
3) Is the SB2129U09YZ runway dropout UL Listed for a data center or telecom room install?
Yes, it carries a UL Listed rating, which is usually what a facility or institutional spec calls for on runway accessories in an equipment room.
4) What is the steel and finish on this Eaton B-Line dropout, and will it hold up in an unconditioned space?
It is 18 gauge ASTM A569 steel with a yellow zinc finish. Yellow zinc plating is an indoor corrosion finish, so it suits equipment rooms, telecom closets and covered industrial areas rather than outdoor or wet exposure.
5) How much room does the runway dropout take up below the runway?
The unit measures 4 in height, 4 in length/depth and 7 in width, and weighs 1.2 lb. Use those figures to check clearance between the runway and whatever sits under it before you set the drop point.
6) Can I add this dropout to a runway that is already installed and loaded?
Yes. The self-drilling screws let you attach it to the stringer in place, so you do not have to pull the runway section or unload cable to add a drop point. At 1.2 lb it is a one-hand piece on a ladder.
7) Is a runway dropout the same thing as a waterfall, or do I need a different part?
For cable leaving the runway, this is the piece that does that job: it is a drop-out that gives the cable a radius as it exits. It is not a runway-to-runway junction and not a conduit fitting, so if you are joining runway sections or branching a run you need splice or junction hardware instead.
8) What part number do I order to match dropouts across a building standard?
Order by MPN SB2129U09YZ, the Eaton B-Line 9 inch yellow zinc runway dropout kit. Specifying that one number keeps every drop point in the facility identical in width, finish and mounting method.
