STEP 1: ATTACHING THE SIDE PANELS TO THE HEADERS
Headers are designed to allow three sizes of opening allowing you to choose
the size of opening that best fits your project needs.
Outside holes for a 60 1/2” opening, center holes are for 54 1/2”, inside holes
are for 48 1/2”. The diagram at right shows a 54 1/2” setting.
Drive the 3 1/2” screw through the top hole in the side panel post, the screw
should stick through about 1/2”. Place the screw point with the appropriate
hole in the header and drive th e screw in the rest of the way. Do not driv e the
second (lower) screw; these will be installed in Step 2.
Repeat the above process with the second side panel on the other end of the
same header.
STEP 2: SQUARING THE ARBOR
The arbor may be squared by using a carpenter square
between the header and side panel or with the aid of a
measuring tape and careful adjustments.
A=b and x=y.
STEP 3: INSTALLING THE CAPS
Securely prop the header end of the arbor 7” off the
ground. Use a 3 1/2” screw to install the first cap
into the marked center point on top of the header.
Use the 9 7/8” spacer block and 3 1/2” screws to
install the remaining caps.

Brace
When the arbor is square, drive the second
screws into the posts securing them to the
header.
Install two of the included braces using 2 1/2”
screws.
Turn arbor 180 degrees by lifting the arbor up-
right and back to the ground so that the second
header is under the posts.
Repeat steps one and two, attaching the header
and braces.
