5. Once the main cover is in place and centered, begin at
the peak of one end and install the wire spring into the
U-channel to secure the cover.
ATTENTION:
Center the main cover front to back and
side-to-side to ensure that enough cover material is
present to lock into the U-channel.
6. Remove the ropes as the cover is secured to the frame.
7. As the spring is install into the U-channel at the top of
the first end rafter, ensure that an even amount of the
cover is exposed and maintained along the edge of the
frame.
8. Continue down both edges of each bay end rafters until
the entire length of the end of the main cover film is
secured in place.
9. Move to the other end of the building and repeat the
steps to secure the main cover in the U-channel.
NOTE:
Pull the cover tight as the spring is inserted into
the U-channel.
10. After the cover is stretched end-to-end and secured
using the spring and U-channel, move to one side of
the frame and repeat the steps to anchor the main
cover to the first side.
Install the Main Cover Film
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.
Continue with the steps that follow.
1. Unpack the cover film and position it at the base along
one side of the frame.
2. Along the edge, make small holes in the cover at
evenly spaced intervals and tie rope or straps to the
cover.
NOTE:
The ropes or straps must be long enough to
reach over the top of the building to the other side.
Long buildings require additional ropes to prevent
tearing the main cover when it is pulled into place.
Keep the holes, used to attach the rope or straps, near
the edge of the material and below where the cover will
be secured to the U-channel.
3. After tying the ropes to the main cover, throw the ropes
over the top of the frame and pull the covers into place.
Use ropes to pull cover over the shelter and onto the
frame. ADDITIONAL ASSISTANCE IS REQUIRED.
4. Center cover side-to-side and end-to-end.
IMPORTANT:
To prevent damage to the main cover
during installation, additional personnel and lifts may be
needed.
