B-LINE SB212912FB – Frequently Asked Questions
1) What does a runway dropout kit like the B-Line SB212912FB actually do?
The SB212912FB is a steel drop-out that mounts to the side or end of a cable runway and gives cable a smooth radius as it leaves the runway and heads down to a rack or cabinet. Instead of copper or fiber bending over a bare steel stringer edge, it rides the curved surface, which keeps the bend radius under control and protects the jacket.
2) Do I need to buy mounting hardware separately for the B-Line SB212912FB dropout?
No. The kit ships with self-drilling screws, so you are not sourcing fasteners or pre-drilling the runway stringer. Bring a driver and you can mount it in place.
3) What size is the B-Line SB212912FB dropout and how much does it weigh?
It measures 10 inches wide by 4 inches high by 4 inches deep and weighs 1.7 pounds. The 10 inch dimension is what you want to check against the runway section you are dropping cable off of, and the low weight means one tech can hold it in place while driving the screws.
4) How do I order the right B-Line runway dropout, and is there more than one configuration?
Order it by part number SB212912FB. It is a single configuration, one model, flat black, with the screws in the box, so there is no finish or size option to specify on the purchase order.
5) Will the flat black finish on the SB212912FB match black cable runway?
It is finished in flat black powder coat, so it blends with black-painted ladder rack and runway rather than standing out the way a zinc or gray piece would. Good call for open racks in a visible room; if your runway is gray, expect a visible color difference.
6) What gauge and grade of steel is the B-Line SB212912FB made from?
18 gauge ASTM A569 hot-rolled carbon steel with a powder coat over it. That is a formed sheet steel part sized to carry the bearing load of cable turning off a runway, not a structural support member, so it should be screwed to the runway rail and not asked to hold rack weight.
7) Is the SB212912FB suitable for outdoor or wet locations?
It is a powder coated carbon steel part intended for indoor cable runway use. Powder coat over A569 steel is not a corrosion treatment for exterior or damp environments, so for outdoor or wash-down areas look at a hot-dip galvanized or stainless pathway component instead.
