INSTALL THE PVC CONDUIT FOR MAIN COVER ENDS
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 then evenly
tightened to stretch the main cover from end-to-end.
Required parts and tools:
• LJ2842 (3/4" PVC conduit) and 103620E (1" strap)
• Duct tape, Tek screws, and Tek screw driver
• Tool to cut strap, a lift or ladders to reach top of frame,
and assistants to install and tighten strap
Photo shows the stretch pocket and the conduit and
strapping as installed for a similar main cover. View shows
the cover as seen when standing inside the frame looking
up at the end rafter.
Complete these steps to install the conduit and strapping
for the stretch pockets of the main cover.
1. Take the first section of PVC conduit and feed it into the
stretch pocket from 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 bell end of the first.

stretch pocket. Cover is shown with the underside facing
up, which is the side visible from inside the frame when the
cover is installed.
