That's the correct answer<:-)) but there's a big difference between
lots and lots.
Just squirt it in your cupped hand and using both hands just slather it
on. Look at the last photo on
As you will notice there's a lot of tape on the leading end of the pull
to give it a tapered shape.
On a 400' run 2 to 4 bottles should be more than enough, depending on
how even you put it on. It takes a bit of experience to get enough on
without overdoing it. Over doing it won't hurt anything, but it sure is
messy. OTOH being soap it's easy to clean up. Most bottles are a
quart or a liter depending on where they come from. I didn't use and
where near a full bottle on an 80' run. It's amazing how much difference
there is between no lube and properly lubed. Just try to cover the
surfaces that will contact the conduit.

Corrugated means no blunt or cable ends on either end of the pull. You
might have to back up and it's easy to get caught on corrugations. Lots
of tape as in the photo and wire soap sometimes just called wire lube,
or pulling lube, or half a dozen other names should make it an easy pull

Usually you are talking about the diameter of the pull. Just go to Home
Depot or Lowe's. The last I purchased was Cable Lube #77 for $5.99 a quart
It's at least a two man job. One to pull and one to feed and soap. n
don't get the freshly soaped pull on the ground. It's like a magnet for
