Main Cover Installation
INSTALL THE PVC CONDUIT FOR MAIN COVER ENDS
The PVC conduit is inserted into notched pockets at each
end of the main cover. Strapping is then threaded around
the conduit and the end rafters. This strapping is evenly
tightened to stretch the main cover end-to-end.
Required parts and tools:
3/4" PVC conduit and 1" strap
•
Duct tape, Tek screws, and driver for Tek screws
•
Tool to cut strap, a lift or ladders to reach top of frame,
•
and assistants to install and tighten strap

Sample Main
Cover to show
pocket location.
PVC conduits are installed near the ends of the main
cover to provide an additional tie-down position. Complete
these steps to install the conduit and strapping for the
stretch pockets of the main cover.
Take the first section of PVC conduit and feed it into
1.
the stretch pocket just above the installed corner cap
from the inside.
Insert the plain end of the conduit into
the pocket so the next section can be joined to the
first.
If needed, cut a small opening in the stretch pocket
2"-4" above the corner cap and insert the plain end
of the PVC into the pocket and continue with the next
step.
Do not cut the main cover; cut only the pocket.
Photo shows the stretch pocket and the installed PVC
conduit at the end of a similar main cover. Feed PVC into
pocket and connect additional sections until the conduit is
assembled and it reaches the same point at the other end of
the pocket.
Once the bell end (lower end of the PVC) reaches
2.
the pocket, take another section of PVC conduit, coat
plain end with PVC glue (customer-supplied), and
insert end into the bell end of the PVC in the pocket.
NOTE:
Wrap the joint using duct tape if desired.
Repeat the steps and continue to assemble and feed
3.
the PVC conduit into the pocket until you reach a
point just above the corner cap on the other side of
the frame. Cut the PVC to the required length.
Repeat the steps to install the PVC for the remaining
4.
end of the main cover.
With both PVC conduits assembled and installed,
5.
verify that the cover is centered on the frame (side-to-
side and end-to-end) and move to one end rafter.
