Just pull through several lengths of that spare Cat6, you can use it
for network, phone, baseband video, all maner of things. Pull them all
together, once you get three or four cables in a duct in can get
remarkably difficult to pull another through, especially of there are
any bends.

One of the secrets here is to sprinkle talcum powder over the cable as
it enters the ducting. It then glides thru quite easily (usually).
