INSTALL MAIN COVER
Gather the parts:
• Main cover (Film or 5.2oz Clear)
• U-channel spring (102198)
• Ropes long enough to reach over the frame (provided
by the customer, or use the anti-billow rope included.)
• Box cutter or utility knife
After attaching u-channel along sides and to the end rafters, install the main cover. Ropes or straps are used to pull main
cover onto and over the frame. The main cover material is typically cut two (2) feet longer than the frame length (e.g.,
length is 48'; film roll is 50'). For some frames, it is possible that the over-the-top dimension exceeds the length of the
frame. Roll out the cover along the frame and take additional measurements to ensure you are pulling the cover onto the
frame correctly.
Complete these steps:
1. Take the cover and position it at the frame base along one side.
NOTE:
Unfold cover and locate edge. Cover ground if needed to protect film and to keep film clean and free of debris.
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.

Actual frame may differ
from example shown.
2. Along cover edge to pull over frame, tie rope (or strap)
around a tennis ball, for example, and
toss free end of
each rope over the frame
. See photo.
This procedure may not be required for small high tunnels;
simply pull the cover over by hand.
NOTE:
Evenly space ropes along side. Number of ropes
depends on building length; use additional ropes spaced
evenly throughout length to prevent tearing cover when
pulled onto frame.
