1.
Unscrew the front and rear plates and the security
screws from the sides. Slide the top and bottom
plates apart.
The filler plate is attached to the rear
plate and should not be removed.
2.
Ensure that the mounting pipe is installed with
the cable access hole facing the rear, away from the
projector screen.
3.
Loosen the four pipe collar set screws
to allow the
top plate to move freely along the pole.
4.
Slide the top plate up the pipe
until the pipe collar is
positioned just above the cable access hole (Figure 2).
Ensure the rear of the top plate is facing to the rear, in
the same direction as the cable access hole in the pipe.
5.
Level the top plate and secure it
by fully tightening
the set screws. At least three screws must come in
contact with the pipe.
6.
Route the cables
so that they exit the pipe via the
cable access hole (Figure 3).

the supplied Velcro pads.
8.

back into the ceiling. Feed the output cables to the
projector via the cable access hole and the bottom of
the pipe.
