INSTALL PVC CONDUIT (CONTINUED)
Shelter shown above may be a different model and
length. Photo used for illustration purposes only.
NOTE:
During this procedure, maintain an even
distance between end rafter and PVC conduit as strap
is tightened.
Also check that bonnet portion of cover overlaps end
rafters evenly at both ends
before
stretching cover.
Check this periodically as cover is stretched.
If side straps are too tight and prevent cover from
stretching end-to-end, loosen but do not remove the
straps as needed and continue.
15. Once strap is tight at one end, cut it to length (if
needed) and tie it to end rafter.
16. At each end of the stretch hem strap, drive a Tek screw
through the strap and into the back side of rafter to
secure strap to rafter.
17. Return to the other end of frame and tighten that
strapping to complete stretching main cover from end-
to-end.
18. Secure strap using a Tek screw at each end (Step 16).
19. Tighten side ratchets by completing next procedure.
14. Beginning at either end, tighten strap. Strapping will
pull against strapping installed at the other end.
TIGHTEN SIDE RATCHETS
Verify that cover is in the desired position and centered on
the frame. (Loosen and reposition if needed.) Continue with
these steps to tighten side ratchets.
1. Move to side ratchets attached to the outside of pony
wall or support posts. Begin with the pair of ratchets
closest to center of pony wall and opposite each other.
2. With someone on each side of the shelter, tighten the
first pair of ratchets opposite each other until cover is
snug. Do not over-tighten.
ATTENTION:
Tightening ratchets opposite each other
simultaneously helps keep cover centered and results
in a more uniform appearance.
3. Move to the next pair of ratchets and repeat the steps
to tighten them.
NOTE:
If strap builds up in ratchet, loosen ratchet,
remove some strap, and tighten.
4. Repeat steps until all side ratchets are snug.
5. Return to all ratchet pairs and repeat the steps to
tighten.
6. After all side ratchets are tight, move to the end of
the pony wall where cover bonnet straps are located.
Tighten these end ratchets to secure cover bonnet.
7. Move to other end and secure cover bonnet.
8. Recheck all ratchets and read care and maintenance
information presented near the beginning of this guide.
