Installation Guide

Main Support Beams & Rafter Placement
12
12 x 12 Flat Top Pergola
Using a helper and two ladders proceed to complete the
following steps:
Slide the main support beam with rafter brackets pre-installed
through both holes of the vinyl column (overshooting), and
then back through both holes of the opposite column.
Please Note:
The top of the vinyl columns may need to be tensioned in opposite
directions to each other to allow the beams and rafters to be
installed on a slight angle. The vinyl columns naturally allow
some measure of flex.
Mount the two 2x6x6’ (5x15x183cm) pressure treated wood pieces
(sold separate) on your wall surface. Please consult your local hardware
store regarding methods of mounting. We recommend 6 lag
screws if mounting to a wood siding or concrete/brick anchor
if you are mounting to a brick wall. Screws heads should be
recessed flush with the wood beam.
To locate the position of your wood beams;
A. Measure half way between the two vinyl posts = 67” (170cm)
B. Mark and draw a string line square to the wall.
C. Measure up 94.5” (240cm) and mark with pencil
D. Measure 3.25” (8.3cm) on either side of the mark. This would
be the bottom corner of the two wood beams as shown.
