MAIN COVER INSTALLATION
After the end panels are installed, install the main cover.
The steps to install the main cover include:
1. The double poly latch U-Channel (#104211) is attached
to each side of the frame and runs from the front to
the back of the shelter. The position of the U-Channel
attaches the cover to the extended cover with roll-up
sides. Tek screws are used to secure the U-Channel to
each rafter.
2. The single poly latch U-Channel (#102197) is attached
to the along the top of each end rafter between the
double U-Channel runs using Tek screws. This
U-Channel is used to secure the main cover. During
installation, the single poly latch U-Channel will bend
with the curve of the end rafter as it is attached.
3. Pull main cover over the frame.
4. Attach the main cover to the end rafters and double
poly latch U-Channel using the poly latch springs.
5. Single poly latch U-Channel will also be attached to
each side of the frame and runs from the front to the
back of the shelter. The position of this U-Channel
identifies the highest "open" position of the roll-up side
panels.
6. Finish the end rafters with single poly latch U-Channel
between the double and single U-Channel that are
attached on the sides of the frame.
7. Attach roll-up covers to the sides of the frame using the
double and single poly latch U-Channel; and poly latch
springs.
8. Install roll-up side kits, the anti-billow ropes, and test
the operation of the twist-of-the-wrist assembly.
INSTALL POLY LATCH U-CHANNEL
Attach double and single poly latch U-Channels along the
frame sides and single U-channel along the tops of the end
rafters between the U-Channel runs.
Gather the parts:
• Aluminum single U-Channel (#102197): End rafters
and sides
• Double poly latch Channel (#104211): Sides
• Tek screws (#FA4482B)
Assembly Procedure
1. Using the pipe joint between the drilled leg pipe and
the curved rafter pipe as a guide, attach the double
poly latch U-Channel flush along both sides of the
frame using Tek screws. The double U-Channel will be
attached over the center of pipe joint. See diagrams
below.
NOTE:
If needed, remove existing Tek screw from the
pipe joint so the double poly latch lays flat against the
rafters.

8" Splice Section
Tek Screw
Tek Screw
Cut one (1) double poly latch channel into 8" pieces
to use to splice the longer double poly latch channel
sections together.
The insert above shows how to splice the joint between
two sections of double poly latch channel. Use Tek
screws and an 8" section of double poly latch channel
and place the channel on the back of the poly latch (or
to the inside of the frame). Install Tek screws through
the double poly latch channel from the outside of the
frame and into the 8" splice section.
