NOTE:
Begin at one end of the U-channel
on the upper
side purlin
and work toward the other, pulling the cover
film down and around the ground posts to secure with
spring.
Maintain an even length along the side. The final
stretching of the cover takes place when the last side is
secured.
11. After securing the upper side purlin, move to the side
U-channel located on the corner posts and secure it in
place.
NOTE:
Pull the cover tight as the spring is inserted into
the U-channel.
12. Repeat steps to secure the cover film to the lower
purlins.
IMPORTANT:
If trimming the excess cover material at
the ends and sides, DO NOT remove too much of the
excess material. Some excess main cover material (the
material that extends beyond the end rafters) should
remain in place to more easily re-stretch the film if
needed.
Dashed line represents the U-channel.
