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, continue with the
