Cable From Below
Pushing cable up into a wall from below can be done using a similar method as dropping it from above.
This time the cable must be pushed up from below. You must measure distances from corners and drill into the supports in the same manner.
The difficulty in cabling from below lies in getting inside a wall when the framing is not visible.
Drilling at an angle may be necessary.
To mark the location, you can drill directly through the floor outside the wall.
Shove a coat hanger through the hole so that it is visible from the floor below.
