B-LINE SB212905FB – Frequently Asked Questions
1) What does a runway dropout kit like the B-Line SB212905FB actually do in a cable runway?
A runway drop-out is the rounded transition piece that mounts at the end or side of a cable runway so cable can leave the runway and drop down to a rack, cabinet, or wall without bending over a bare metal edge. The B-Line SB212905FB is that piece in flat black powder coat, and it ships with the self-drilling screws needed to attach it to the runway stringer.
2) Do I need to order screws or hardware separately for the B-Line SB212905FB dropout?
No separate fasteners needed. The kit includes self-drilling screws, so it goes straight onto the runway stringer with a driver. You supply nothing but the tool.
3) How big is the B-Line SB212905FB runway dropout, and will it fit at the end of my ladder rack?
The dropout measures 5 in wide, 3 in in length/depth, and 2 in in height, and weighs .6 lb. Check those numbers against the stringer depth and the clearance at the point where your runway terminates, since the piece has to sit flush on the stringer face for the self-drilling screws to bite.
4) Is the B-Line SB212905FB dropout UL Listed for a data center or telecom room install?
Yes, it carries a UL Listed marking, which is the line most institutional and government spec sheets want to see on runway accessories before they will approve the submittal.
5) Will this dropout match black cable runway that's already installed?
It's finished in flat black powder coat, so it matches black-finished runway and ladder rack rather than the gray or zinc finishes. If the rest of the room is gray runway, this one will stand out.
6) What is the exact part number to order this B-Line dropout, and is aluminum an issue in a damp room?
Order it as Eaton B-Line SB212905FB. It's aluminum with a flat black powder coat, so it won't rust the way bare steel does, though the powder coat is the primary protection and it should still be kept out of standing water.
7) How many dropouts do I need for a cable runway run?
One per cable exit point. A drop-out is placed wherever bundles leave the runway, typically above each rack or cabinet and at the wall penetration, not once per run. At .6 lb each the added load on the runway is negligible even with several installed.
