Depends on the tent really. Some tents have slide tracks that some shops custom fab hangers for. Other tents have a
unistrut like
channel ( but it mostly certainly is NOT
unistrut compatible) that shops custom fab hangers for. Some tent roofs have straps that run along the edges you can pull cable through. Other tents are just poles or none of the above, in which case zip ties or tie
line is your best friend. There is no easy way. I try to run my cables down one side of the tent and then run the cables up the ribs. Cable ramps are often also a necessity.
The Light Source also makes and will custom fab cheeseburgers to fit I the larger round tent uprights.
