Wood Post Layout & Installation
for In-Ground Application
Measure and mark out the location of the
p
ergola
p
osts using
string line and tem
p
orary wood stakes. Diagonal distances must
be the same to ensur
e a squa
re installation. Adjust string lines
accordingly. The inside corner of the string lines will be the
p
ost
location.
Please Note:
Should you decide to moderately modify the dimensions of your
pergola from the standard kit size, a circular saw with a sharp
fine-tooth blade is all that you need to cut, shorten or modify the
vinyl components.

This pergola can also be installed on a pre-existing wood or
concrete surface using our bolt down bracket system with
a 4x4 wood post (sold separate). See page eight for more details.
Post location and placement is the most critical step in the
overall installation process. Please double check for the
possibility of any underground utilities such as sprinkler, gas
or telephone lines.
STEP ONE
After you ha
v
e determined where the
p
osts will be located,
exc
av
ate 10” diameter x 36” d
eep p
ost holes.
After holes are dug and cleaned,
pl
ace the 4x4 wood
p
ost into
a hole ensuring it’s le
vel and squa
re to string lines. The final
p
ost
height should be no more than 84” out of the ground. If a
p
ost
is higher because of obstructed exca
v
ation of footings,
plea
se
cut down in height accordingly.
Fill the
v
acant hole with
p
re-mixed concrete all the way to
within 3” of the t
op
of the hole. After the concrete has set, back
Re
p
eat for all four
p
osts.
Please Note:
Some 4x4 pressure treated posts can be larger than 3 1/2 x 3 1/2
square due to twisting or cracking. We have allowed a tolerance
for this in the internal one way and two way 4x4 wood post guides
(see page 8). However in extreme cases you may need to shave down
the top of the 4x4 wood post slightly to get the vinyl post started
over the wood post. Before installing your wood posts in the ground,
please check to confirm this and correct at this stage if necessary.
