6. Move the band clamps into position by sliding each to
its location marked on the rafter in Step 2.
7. After assembling the rafter, securing the joints, and
setting the band clamps in position, cut a length of
rope (or cable) that is the width of the shelter plus and
additional 12 inches.
8. After the rope (or cable) is cut, insert approximately 6"
through the rafter foot mounting holes at the bottom
of the rafter leg and clamp the rope in place with the
clamp on the outside as shown below.
9. Insert the remaining end of the cable through the other
rafter bolt holes, measure the 28' on-center width
dimension, and clamp the legs in place to prevent the
rafter from spreading as the struts are attached.
10. Position three (3) sections of the 166S099 pipe (99"
each) and one (1) 166P040 pipe (40") on the ground
between the rafter legs, slide two (2) of the smaller
band clamps (QH1402) onto one of the center pipe
sections, and assemble the chord.

11. Secure each pipe joint of the chord with one FA4484
Tek screw. Standing on the chord assembly helps to
keep the pipes from turning as the screws are installed.
Be certain each joint is properly seated before installing
the screw.
Band clamp locations may differ from actual locations.
