Step 5:
One at a time, slide purlins through the rest of the clamps and tighten the bolts with the
ends of the purlins a half inch past the edges of the clamps on the end rafter.
Step 6:
After you have installed the first two rafters, slide a brace band onto each of the two bottom
purlins (before you go on to attach the third rafter).
Step 7:
Using 1-1/2" carriage bolts and nuts, attach struts between the brace bands on the purlins
and the brace bands on the end rafter. Position the struts so that they form a triangle at roughly
a 45° angle when installed. Make sure the end rafter is plumb before you tighten the nuts.
Tip:
If you forgot to slide a brace band into position on a rafter or purlin, you can wedge the
brace band onto the pipe by striking it with a mallet.
Be careful, and wear eye protection!
You can then reclose the end of the brace band by pinching it with slip joint pliers if necessary.
