12 x 16 Attached Flat Top Pergola
Using a helper and two ladders proceed to complete the
following steps:
Mount the main support beam which has the rafter hangers
onto the wood boards as shown. The top of the wood beam
should be flush with the top of the pergola beam.
Align the joiners to be between the 4” (10.2cm) gaps between
the wood boards mounted in the previous step.
To fasten, use a minimum of eight 3½” (9 cm) lag screws
through the main support beam and wood beam. Space the
lag screws between the rafter hangers.
Place the nine rafters into the rafter hangers & rafter brackets.
Ensure that they are pushed all the way in the rafter hangers.
Fasten into the rafter hanger using four - 5/8” (16mm) screws as
shown.
Fasten the rafters onto the rafter brackets using
5/8” (16mm) screws as shown.
Using 4“ (102mm) screws, lock the rafters into position inside
the posts by driving in 8 screws from the outside and 8
screws from the inside of each column.
