Multiple Story MDUs/Exterior Installation
It may be simpler to run the cable on the outside of the building up to each floor or each apartment. A separate
cable will be needed for every unit. As always, make a thorough visual inspection of the proposed route and all
outlet locations.
Prior to installing the cable, read page 9.4 for the methods needed to locate and drill your entry hole.
Running Cable to Each Unit
Use a ladder of greater height than required or a bucket truck to run the cable up the side of the building. Look
for vertical and horizontal architectural elements that will help disguise the installation. Be sure you are using an
outdoor-rated cable.
Take the cable end with you up to the entry point.
Form more cable that you will need (you can never
use too much) into a loose loop. Tie off the loop with
a cable tie and attach the cable to the building wall
with a cable clip. Don’t let the loop hang free until
you have at least two clips in the wall.
Continue to attach the cable to the wall using clips
every 3 feet (1 meter) until you reach the point where
you want to turn downward. Being careful not to exceed
the bend radius, attach the cable to the wall as
you descend.
Return to the entry point and enter the wall as described
on page 9.4. Untie the cable loop and feed
the cable through the hole.
