INSTALL MAIN COVER
Gather the parts:
• Main covers and inflation fan kit
• U-Channel spring (#102198)
• Ropes long enough to reach over the frame (provided
by customer)
• Box cutter or utility knife
Assembly Procedure
After the poly latch U-channel is attached to the frame,
unpack the main cover and pull into place. Ropes or straps
are typically used to pull the main cover onto and over the
frame.
WARNING:
To prevent damage to the cover and to
prevent serious personal injury, DO NOT attempt to
install the main cover on windy or stormy days.
Consult the Spec Sheets for cover identification. The
greenhouse is equipped with double-layer main cover and
an inflation fan kit. One cover is pulled into position and
anchored to the frame, then the inflation kit is installed, and
finally the last main cover is attached.

Top edge of the end rafter
NOTE:
Cut the remaining 2' section into 8" pieces
to use to splice the longer double poly latch channel
sections together.
5. The insert 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
poly latch channel from the outside of the frame and
into the 8" splice section.
Double poly latch is attached along the sides of the
shelter only. Single poly latch is attached to the top of
each end rafter.
6. Continue by attaching the 8' double poly latch sections
to the rafters and work toward the other end of the
frame. Cut the last 8' section of double poly latch to the
required length so that it is flush with the outside edge
of the end rafter.
ATTENTION:
Use the remainder to finish the other run
of double poly latch channel.
7. Repeat these steps to secure the double poly latch
channel to the other side of the frame.

4. To begin,
cut one 8' section
of double poly latch
channel to 6' and attach the 6' section to the rafters
using Tek screws. Attach the poly latch channel flush
with the outside edge of the end rafter. Use the chalk
line as a guide to position the poly latch channel.
INSTALL POLY LATCH U-CHANNEL (continued)
8. After attaching the double poly latch to the sides of the
frame, measur
e between the two runs of double poly
latch channel at one end rafter
to determine the length
of the single U-Channel. See the dashed line below.
9. Cut the single poly latch U-Channel (if needed) and use
Tek screws to attach the single U-channel to the top
edge of the end rafter.
Insert above shows the installation of poly latch U-
Channel on top of an end rafter. The poly latch U-
Channel will bend with the curve of the rafter as it is
attached. Dashed line shows where to install the single
poly latch U-channel.
10. Repeat the steps to install the single U-Channel at the
remaining end of the frame.
11. Continue with the installation of the main cover.
