Sturdiest:
DIG post HOLES
ABOUT 2 FEET DEEP
Measure the differences in elevation,
and cut the bottoms of the posts to
accomodate for any slope
Adjust the holes to make the bottoms
level in elevation. Do not fill & tamp till after
you complete the step on page 7.
INSTALL POST ANCHORS
ONTO EXISTING CONCRETE*
Gravel for drainage
Tamped dirt
OR
For ledgered pergolas, half of the posts are replaced
by a ledger beam attached to your structure.
You will need to determine the strength
of your foundation and/or ledger
attachment method.
Titan Post Anchors are optional with each kit.
They provide increased vertical support, especially
for free-standing pergolas. Initially, install with only
2 screws and not all the way tight (see page 7).
Set posts with
3x3 notches
“stepping down” toward
the inside of the pergola.
GRK Caliburn
Concrete Screws
Check with your local building department for post foundation and/or ledger requirements.

4
Inner Beam
Inner Beams sit in the notch at the top of the 6x6 posts, and should be flush to the ends
of the posts. Attach with two 5” screws at each post. Pre-drilling is not necessary for all
of the 5” screws unless going through a knot.
OC Spacing
Rafter spacing (in inches) = (length of Inner Beam - 3”) ÷ ( # of Rafters - 1)
Mark your rafter spacing on top of the inner beam, before placing your inner beam.
5" Construction Screw
x2 per post

5
Outer Beam
Outer Beams extend one foot past the Inner Beams on each side and feature decorative cuts
to match the Rafter Tails. Attach the Outer Beam to the Inner Beam with one 5” screw at every
Rafter location. Offset from the center of your markings so the 10’ screw will not hit it.

Rafter Tail Rafter

Outer Beam
*An alternative method for joining the Inner and Outer Beams so that
the Rafters and Rafter tails are flush to each other across the top
(see page 8) is to layout the Rafters and Rafter Tails upside-down on
a flat surface. Then, place the Outer Beams upside-down into the
grooves created by the rafter tails, then attach the Inner and Outer
Beams together at each rafter location with 5”screws, before
installing this beam assembly on the posts.

10" Construction Screw
1 at each end of each Rafter
Pre-drill outer rafters with a 1/4” x 6“ drill bit, then set and
attach with 10” screws with the T-40 driver bit.
Pre-drill at a slight angle from the rafter
into the inner beam.
6
Outer Rafters
Square the frame and
level the posts before
attaching the braces.

Rafter Braces are longer
than Beam Braces, so that
they rest at the same level
on the bottom as the
Beam Braces.
Beam Braces are shorter
and rest under the
Outer Beam and next
to the Inner Beam.

Braces
After attaching the outside rafters and braces, secure the posts to the
ground, or tamp dirt around post evenly, checking for level as you go.

Inner Rafters
Pre-drill remaining rafters, then set and attach with 10” screws.
Pre-drill at a slight angle from the rafter into the inner beam.

9
Rafter Tails
5" Construction Screw
x2 per Rafter Tail
Rafter Tails sit on the Outer Beam, aligned with the Rafters.
They are pre-drilled through the notch and attach to
the Outer Beam with two 5” screws.
Do not attach tightly you
will need to align them
with a purlin during
the next step.

Shade Purlins
Attach Shade Purlins with a 12” overhang on
each side. It helps to measure, calculate
spacing, and mark the Shade Purlin
locations on the Outer Rafters.It also
helps to pre-drill and pre-load the
Shade Purlins with 5” screws on
the ground before installation.
Purlins are usually spaced 8” OC.
5" Construction Screw
per Purlin/Rafter connection
You can put fewer screws as long as the
purlins are secured at each end and
staggered at least at every-other rafter.
Be sure to calculate, measure out,
and then mark your spacing so it
looks even on both end of
the rafters.
