Wood Post Layout & Installation
Using Bolt Down Brackets
for Concrete or Wood Surface
Measure and mark out the location of the bolt down brackets
using string or chalk line. Diagonal distances must be the

Mark out the location of bolt down brackets as illustrated .
Using a 3/16” masonry drill bit, drill 3” deep holes to allow
installation of 2 3/4” concrete screws (Not included)
Proceed to install three 2 3/4” concrete screws into the bottom
base of the bolt down bracket (Not included)
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

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).
