OPTIONAL MAIN COVER INSTALLATION W/ ROLL-UP
SIDES (CONTINUED)
Photos show installing the spring into the U-channel on
the outside of a frame. The process is the same for the
U-channel attached to the top of the end rafters.
5. Continue adding the spring 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 as it is attached.
NOTE:
The cover material is cut longer/wider than is
required to cover the frame. For easier anchoring, allow
approximately 10" to extend past the edge of the end
rafter as the cover is anchored in place.
6. Continue down both edges of the first end rafter
until the entire length of the end of the main cover is
secured in place.
7. Stretch the cover 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.
8. 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.
Begin at one end of the U-channel and work toward the
other. It is also possible to begin at the middle of each
side and work toward each end.
NOTE:
Maintain an even length along the side. The
final stretching of the cover takes place when the last
side is secured.
9. After securing the first side, move to the remaining side
and secure it in place.
IMPORTANT:
DO NOT REMOVE TOO MUCH OF THE
EXCESS COVER MATERIAL AT EACH END.
Some
excess main cover material–the material that extends
beyond the end rafters–should remain in place. If the
main cover needs stretched in the future, remove the
spring from the U-channel, grasp the excess material,
pull the cover tight, and reinstall the spring.
The excess material along the sides is rolled up in the
roll-up side assembly.
10. Once the main cover is installed and secured in the
U-channel, follow the instructions provided with the
Twist-of-the-Wrist Assembly if used.
11. Once you have completed the Twist-of-the-Wrist
installation and install your Anti-Billow ropes, read the
Care and Maintenance
section that follows.
