Step 4:
Secure each connection by inserting a Tek screw into the side of the arch.
Tip:
Tek screws are self-drilling and no pilot hole is usually required. If you have trouble
getting a Tek screw to “bite,” try another Tek screw (or you can drill a 3/16" pilot hole).
Step 5:
Repeat the steps above to assemble all remaining rafters using the same procedures.
Two of your rafters will be used on the ends of your shelter, and these end rafters use special fittings
including Purlin End Clamps and Band Clamps. You will add these fittings now.
Step 6:
Slide 3 sets of Purlin End Clamps onto one of the rafters. These will be be used to secure
the purlins to the end rafter. Turn them as required to get past the Tek screws at the joints.
You
ʼ
ll need one at the top of the rafter and one on each side of the rafter at the joint.
Tip:
On the sides of the rafter, position the top strap of the end clamp so it rests on the Tek
screw. This will help prevent the clamp from slipping if the purlin has to support any weight.
