Wood Post Layout & Installation
Using Bolt Down Brackets
for Concrete or Wood Surface
Measure and mark out the location of the pergola posts using
string or chalk line. Diagonal distances must be the same to
ensure a square installation. Adjust string lines accordingly.
The inside corner of the string lines will be the post location.
Mark out the location of bolt down brackets as illustrated.
Using the 5/32” masonry drill bit included in your bolt down
bracket kit, drill 3” deep holes to allow installation of 2 1/2 concrete
screws included in your kit.
Proceed to install three 2 1/2 concrete screws into the bottom
base of the bolt down bracket.
Please Note:
Concrete patios generally have sloped surface for water run-off.
If this is the case, when you secure the bolt down bracket to the
concrete, the bracket may be at an angle. This can be corrected
for level using galvanized steel washers (not provided), acting
as shims underneath the base to level -
VERY IMPORTANT OR
PERGOLA BEAMS AND RAFTERS WILL NOT BE LEVEL.

With the four post brackets installed plumb, proceed to set
the 4x4 x4’ wood post in place. Secure using the same concrete
screws included in the kit. Repeat for all 4 posts.
Posts should be approximately 48” in height.
In order to create a snug fit between the wood posts and the
inner cavity of the vinyl posts, it will be necessary to ‘build out’
the 4x4 posts near the bottom and the top using 1/2” x 3 1/2” x 12”
shims on all four sides (not supplied).
