8. Installation
Rafter Installation and Floor Support Angle Attachment
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° to each other. Two (2) of the first three (3)
rafters should all face the same direction and be from bundle of eleven (11) rafters. Every other rafter
should alternate direction. IMPORTANT: There are left and 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
three (3) 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.
