INSTALL THE PVC CONDUIT FOR MAIN COVER ENDS
For some covers, the PVC conduit is inserted into a pocket 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:
LJ2842 (3/4" PVC conduit) and 103620E (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

PVC conduits installed near the ends of the main cover 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 the stretch pocket from
1.
the bottom at one end of the cover.
Insert the plain end of the conduit into
the pocket so the next section can be joined to the first.
Photo shows a similar cover and
the location of the stretch pocket.
Cover is shown with the underside
facing up, which is the side visible
from inside the frame when the
cover is installed.
For some covers, the notched
portion of the stretched pocket
is removed in the field by the
customer.

NOTE:
Some covers may
not ship with the pocket
material removed for the
installation of the straps. If
slots need to be created,
cut only the cover pocket;
do not cut the main cover.
Space slots approximately
24" apart (on-center) if
these need created.
