Step 8:
Continue adding rafters (at 48" spacing) and purlins until all inside rafters are in place
between the two end rafters. Remember to use the other end rafter last.
Step 9:
Using 1-1/2" carriage bolts and nuts, attach struts between the end rafter just installed and
bottom purlins as you did at the other end of the frame.
Step 10:
With all rafters and purlins in place, position the shelter exactly where you want it located.
Step 11:
Recheck the 48" rafter-to-rafter dimensions along all the purlins. Also check that every raf-
ter is standing up straight (plumb). Square the corners by measuring diagonally corner-to-cor-
ner, and line up all rafters using a straight line.
Step 12:
Secure every joint between purlin sections with a Tek screw.
