Using a helper and two ladders proceed to complete the
following steps:
Raise one Main Support Beam Assembly at a time and insert
the 9” Bolt Assembly into the holes to hold into place as shown.
Some force may be required to get the bolt through.
Do not tighten the nuts until all four beams are in place,
instead, simply hand-tighten them.
Fasten the main support beams onto the Posts using the 4” (102mm)
screws provided (8 screws per post) through the pre-drilled holes.
Place the rafters onto the main support beams as shown.
Space the middle two rafters 42” (106.7 cm) apart (Critical for louver
placement)

Note: The 9" Bolt Assembly is used to properly position the main
beams on the columns.
Once all four main support beams are in position, use two
wrenches to tighten the nuts. Stop once the bolts bottom out
inside the nuts. Over-tightening the nuts could cause damage to
the bolts.
