Installation Guide

Wood Post Layout & Installation using
Bolt Down Brackets for Concrete or
Wood Surface for Attached Pergola
Measure and mark out the location of the bolt down brackets using
string or chalk line. Adjust string lines accordingly. The inside
corner of the string lines will be the corner of the bottom flange.
Mark out the location of bolt down brackets accordingly using
the base of the bracket accordingly.
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
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 two post brackets installed plumb, proceed to set
the 4x4 x7’ wood post in place. Secure using the same concrete
screws included in the kit. Repeat for both posts.
Posts should be 96” in height.
In order to create a snug fit between the wood posts and the inner
cavity of the vinyl posts, it will be necesary to “build out” the 4x4
posts near the bottom and the top using 1/2” x 3 1/2” x 12” shims.
Follow instructions as illustrated.
Please Note:
Some 4x4 pressure treated wood 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 post brackets and the internal one way and
two way 4x4 wood post guides. However in extreme cases, you
may need to shave down the end of your 4x4 wood post slightly
to allow access.
