Ledger Boards and Main Support Beam
Placement
13
12 x 12 Flat Top Pergola
Using a helper and two ladders proceed to complete the
following steps:
Position and place the two main support beams onto both
sides of the posts.
Fasten the two beams to the post by using the bolt assembly
that comes with the hardware kit. You’ll need two wrenches
to fasten the nuts and bolt.
Mount the two 2x6x6’ pressure treated wood pieces (sold se-
parate) on your wall surface. Please consult your local hardware
store regarding methods of mounting. We recommend 6 lag
screws if mounting to a wood siding or concrete/brick anchor
if you are mounting to a brick wall. Screws heads should be
recessed flush with the wood beam.
To locate the position of your wood beams;
A. Measure half way between the two vinyl posts (67”)
B. Mark and draw a string line square to the wall.
C. Measure up 98 1/2” and mark with pencil
D. Measure 3.25” on either side of the mark. This would
be the top corner of the two wood beams as shown.
