B-LINE SB212920FB – Frequently Asked Questions
1) What does a B-Line runway dropout kit actually do on a cable runway?
It gives cable a smooth radius where it leaves the runway and drops down to a rack or cabinet, so the bend radius is controlled instead of the cable pulling over a bare rung or edge. Tie down holes are built in so you can dress and secure the bundle right at the exit point.
2) What size is the B-Line SB212920FB runway dropout kit?
The stated dimensions are 18 in width, 4 in height, and 4 in length/depth, so it is sized for an 18 inch wide runway. If your runway is a different width, you need the dropout matched to that width.
3) What material and finish is the B-Line runway dropout, and will it match black ladder rack?
A569 steel with a flat black powder coat, 18 gauge. That matches the standard flat black finish used on B-Line series runway, so it blends with existing black ladder rack in a telecom room rather than standing out.
4) How heavy is the B-Line SB212920FB dropout kit for handling and shipping?
Listed at 30 lb. Plan on a second set of hands overhead when mounting it to a runway at ceiling height.
5) Do I still need cable ties and hardware for a runway dropout, or is everything in the kit?
The dropout has tie down holes punched in it, but the ties themselves are not part of it. Order your cable ties or hook and loop wrap separately and use the provided holes to anchor the bundle at the exit.
