Installation
I At least two other people are required to hold
and control the awning hardware until the
top mounting brackets and back channels are
correctly installed.
4. While one person guides the awning fabric (with the
awning roller cover, if equipped) into the awning rail,
carefully move (carry) the awning hardware assembly
to the desired location.
6.2.2 Attaching the Top Mounting
Brackets/Arm Assemblies

WARNING: IMPACT AND/OR PINCH HAZARD.
Arm assemblies are under tension from the gas strut.
Hold the arm assemblies and the FRTA securely
before removing ties. Otherwise, the arms will
extend quickly and unexpectedly. Failure to obey this
warning could result in death or serious injury.
NOTICE: Control the arm assemblies while installing the
brackets. When the weight of the FRTA is not supported,
downward force could cause the arm assemblies to
swing sideways and damage the RV.

I Some awning rails have a wide drip channel
to catch water as it runs off the RV roof. If the
awning rail is too wide, it may be necessary to
lower the position of the top mounting brackets
to avoid interference with the FRTA.
2. While holding the arm assemblies securely in place,
mark the top mounting bracket hole locations.
3. Determine the location of the wiring harness hole
on your model. See "Back Channel Hardware
Dimensions" on page 4.
I The back channel will either have a notch at the
top, or a hole near the bottom for wiring to pass
through the RV wall.
– If the wiring will pass through the RV wall at top
of the back channel, mark the wiring hole (notch)
location.
– If the wiring will pass through the RV wall at the
bottom of the back channel, go to the next step.
4. Carefully move the arm assemblies out of the way to
expose the marked mounting hole locations.
5. Drill 3/16 in. diameter holes through the marked
mounting hole locations and into the solid structure
of the RV.
Drill 7/32 in. diameter holes if drilling into steel.
I
6. If the wiring will pass through the RV wall at the
bottom of the right-hand back channel, drill a 5/8 in.
diameter hole at the marked top wiring hole location
and through the outside wall of RV.
