Using the vinyl weld glue, insert the One Way 4”x4” Internal
Wood Post Guide in the one end of the main column posts.
This step is only applicable if your wood 4x4 post are embedded
into the ground. If your pergola is going to be installed on
wood or concrete surface, please dispose of these four pieces.
Using a step ladder, guide the bottom vinyl columns over the
wood 4x4 posts .
If you purchased base moldings or trims, slide the molding over the post.
Using a step ladder guide the top vinyl columns over the
wood 4x4 posts.
Please Note:
Ensure that holes at top of column are orientated correctly for
future beam and rafter placement. See diagram at top of next page.
Connect the bottom and top vinyl column by using vinyl weld
and sliding together. Please Note: Vinyl Weld Glue has about a
sixty second cure time and about a 20 minute dry time.
Slide the bottom post trim into position to cover the joint on
the column.
Slide the top post trim into approximate position just below the
bottom routed hole on the bottom of the top vinyl column assembly.
If necessary, adjust post heights accordingly to ensure future
level installation of beams and rafters as necessary. If slope is severe
causing a height difference between the posts, you may need
to trim down the bottom of two or more of your vinyl columns
as necessary.
Secure the vinyl columns to the wood posts using 4 – 2 1/2“
(64mm) self-auguring stainless steel screws at 8” (20.3cm)
up from the base of the posts, and 4 – 2 1/2” (64mm) self-
auguring stainless steel screws just above the trim cap as
illustrated. This will prevent possible uplift during high winds, etc.
If base moldings are installed, place screws above the
base moldings.
