B-LINE SB78706 – Frequently Asked Questions
1) What does a runway dropout kit actually do on a cable tray or ladder rack?
The Eaton B-Line SB78706 is a universal drop-out that mounts at the point where cable leaves the runway and heads down to a rack or cabinet. It gives the cable a smooth radius to bend over instead of a bare rack edge, so the conductors are not kinked or crushed as they exit. It is a cable management accessory, not a structural rack part.
2) Is the B-Line SB78706 drop-out UL Listed for a telecom room install?
UL Listed, yes. That is the certification carried on the SB78706 drop-out kit, which is what most spec writers and AHJs look for on runway accessories in a communications room.
3) Will this drop-out work on runway from another manufacturer, or only Eaton B-Line ladder rack?
It is built as a universal drop-out, so it is not tied to a single runway series. Confirm your stringer spacing against the 5.44 inch width before ordering a quantity for a full room.
4) What is the SB78706 made of, and will the finish match my existing telco runway?
Aluminum with a telco gray powder coat. That is the standard finish on B-Line runway systems, so it blends with gray ladder rack already in a data or telecom room, and aluminum keeps corrosion down in conditioned indoor spaces without adding weight.
5) Do I need a drop-out at every cable exit point on my ladder rack?
Anywhere cable leaves the runway and turns down over an edge is where the SB78706 belongs, since its job is to provide the radius at that turn. Runs that stay on the rack and terminate elsewhere do not need one. Facilities standardizing a whole room typically count one per rack or cabinet drop.
6) Is the SB78706 one part number or do I have to pick options?
Single part number, SB78706, sold as a kit. There is no handing, size, or finish choice to specify, so ordering by quantity is all that is needed. Mounting to the runway is separate hardware if your rack does not already have it.
