Jet line is polypropylene pull string, named after a common brand and sold in buckets so it pays out freely. A foam piston called a mouse or carrier is tied on and blown or vacuumed through an empty conduit with a power fishing system, and the string then pulls in a heavier rope, mule tape or the wire itself. It is also left in empty conduits for future pulls, tied off at both ends.
Blow a jet line through all the empties to the roof and tie them off so the next guy has something to pull with.
