I spotted this on our hike.
We wrapped five 200 foot segments of the direct burial line back onto the original spool so we could tape them all together. The paint cans are ballast to keep the spool from sliding around.
Our first pull attempt was thwarted by friction. We yanked it back and greased the nose of the cable and it went through well.
The cables then had to be completely un-spooled again, the opposite end taped, and then pushed through three more short conduit runs. It comes out of the wall in the sound room of the sanctuary.
This should better re-use than zip ties
