Assemble and Install Center Collar Channels and Cap Plates
The following procedure is for assembling the center collar channels and cap plates on the ground, and lift-
ing the entire assembly as one unit.
1. Locate a short center collar channel (F), and install a short channel clip (D) to the outer edge of the
short center collar channel (F).
2. Install flange bolts (C) and flange nuts (E), and repeat this procedure for the opposite end of this
short center collar channel (F).
3. Install one 3/8 in. bolt (B) and nut (A) into the center hole of the short center collar channel (F) to aid
with water shedding,
NOTE: Installing the 3/8 in. bolt (B) and nut (A) will create a slight pitch when the center cap plate is
installed, allowing water to shed from this area.
4. Locate the second short center collar channel (F), and repeat this procedure.
5. Place both assembled short collar channels (F) aside to use later in this procedure.
