sides and tops of the greenhouse
end rafters
.
2. Pull one cover film over the frame and attach to the end
rafters.
3. Stretch and attach the first cover to the sides.
4. Install the Inflation Fan kit.

INSTALL POLY LATCH U-CHANNEL
Gather the parts:
• Aluminum U-channel (#102197)
• Ribbon board (supplied by customer)
• Tek screws (#FA4482B)
1. Measure the desired height to identify the top of the
roll-up sides.
NOTE:
For the roll-up side panel to function properly,
the poly-latch channel attached to the sides of the
frame must remain below the curve of the rafter.
Attaching a ribbon board (not included) to the rafters
and then attaching the poly-latch U-channel to the
ribbon board is recommended for the best results.
Consult the diagram below for clarification.
2. Attach one section of the poly latch U-channel to the
side of the frame using Tek screws. Attach U-channel
flush with the outside edge of the end wall panels.

and are
supplied by the customer.
NOTE:
The single poly latch is attached to the sides
and tops of the end rafters.
3. Continue to attach the U-channel sections to the rafters
(or ribbon board if used) and work toward the other end
of the frame. Cut the last section of U-channel to the
required length so that it is flush with the end wall panel
(if needed).
4. Repeat these steps for the remaining side.
5. After
attaching the U-channel to the sides of the frame,
use Tek screws to attach the single U-channel to the
top edge of the end rafters.
Insert 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.

installed on the top of
both end rafters
