When installing the rafters, set the lower clip end on the "C" eave member. Leave the bolts to the center collar and the
eave member loose until all rafters are in place. Use 3/8" x 1" hex bolts and nuts to connect the center collar and eave
member to three (3) rafters at 90 degrees to each other. These first three (3) rafters should all face the same direction.
Every other rafter should alternate direction. IMPORTANT: There are left & right rafters. Be sure to alternate left,
right, left, right, etc.. The floor sheet support purlins can now be installed using 5/16" x 3/4" bin bolts. There are two
(2) different lengths of purlins to fit between the rafters. Insert the straight tab of the purlin through the upper slot in
the left hand rafter when looking toward the bottom of the rafters. Bolt the bent end of the purlin to the right hand rafter
in the upper two (2) holes. After inserting the next purlin tab, bolt the first purlin tab to the second purlin. Continue
around the bin alternating lengths as the rafter facings did. Tighten all bolts.
