STEP 3 – INSTALL POSTS OVER POST MOUNT
a)
Double check desired height
of pergola roof and mark each
aluminum post mount at the
top of the beam – simplest way
(short of using a laser level) is
to quick clamp your beams to
your post mounts and mark the
mount at the desired height.
Cut aluminum post mount 8
b)
½" below this mark - Use any
circular saw with a non-ferrous
blade. It is important that the
cut be as square as possible.
This will help the Post Top Plate
to sit level. We recommend that
you trace your cut line around
the post with a speed square.
c)
Slide the Post Mount Standoff
over each post. These provide
a friction tight fit between
the post and post mount.
They will sit on the top of

Insert the Post Top Plate into
the top of your post mount.

the top of the Post Top Plate.
Cut your vinyl post 9" longer
than this measurement.

sides are caulked adequately.
b.
Remember, your vinyl
post will stick up 1" taller
than the top of the 2x8
box beam to allow room
to fit in the post cap.
c.
If the bottom of your
post will be visible upon
completion you will want to
take extra time to ensure to
cut the post off as square
as possible. This is best
done by tracing your cut
line around the post with a
speed square and cutting
carefully and slowly.
g)
Slide the post over the top of
the mount. If you purchased
the post skirts, slide those
over the post next.
