Poly Latch Channel on the Hipboards and
Baseboards:
Poly Latch Wire and Poly Latch Channel
are used to hold the main covering in place and secure it
along the length and above the roll up sides. Hereafter
we will simply refer to them as “wire” and “wire channel”.
a. Using #10 x 3/4" phillips self-drilling tek screws about
every 12", secure lengths of channel end for end down
the middle or lower side of the outside of the hipboard
for
the full length of the tunnel.
Cut off any excess on
the opposite end so it is flush to the end of the
hipboard.
b.
Prepare a section of wire channel to hold an overlap
panel of plastic that will prevent drafts and heat loss at
the ends of the roll-up sides
(shown on page 27) as
follows
: Cut to length and secure a 4’ 2”
section of wire
channel. Secure it to the end wall bow and the next bow
in
with #10 x 3/4" phillips self-drilling tek screws
.
You
may allternatey secure it to the top of the outside face
of the baseboard if desired.
c. Using clamps, hold cut-to-length pieces of wire
channel in between the hipboard and baseboard on
the outside edge of the first and second groundposts.
Secure with #10 x 3/4" phillips self-drilling tek screws
