HEADERS PREPARATION
We recommend a maximum header length of 12 feet for 2x6 headers and 16 feet for 2x8 headers. The recommended rafter
lengths are 12 feet for 2x6 rafters and 16 feet for 2x8 rafters. We further recommend that you allow for 18” of overhang
beyond the posts on each side for the headers and 18” overhang beyond the headers on each side for the rafters.

Header and Rafter Tail Designs Cutting
Visit www.

to see our collection of Rafter Tail designs. Based on your cosmetic
preference and skill, select a rafter tail design shape that you plan to cut yourself or you plan to outsource the design cutting.
You may have your own design that you wish to apply to the rafter tails. The possibilities for rafter tail designs are endless.
However, even a small change in detail can add a dramatic flair to your pergola design. Be creative.

Rafter Tie Brackets Installation
After you determine the lengths for your headers, it is time to prepare the header to install the rafter tie brackets. We have
designed the rafter tie brackets to be auto aligning and simple to locate precisely. Follow these steps for easy rafter tie
placement:
1.
On the ground, place headers with the top edge of headers facing upward. Butt two headers together and align their ends
flush.
2.
Clamp headers together using a C-clamp or other vice.
3.
Measure and find the center along the header length. Mark a line at the center point on both header top surfaces.
4.
Measure outward 16 inches, incrementally, and mark a line at each 16” point out from center until you reach the end of the
header on each side.
5.
Separate the two headers by removing the clamp.
6.
Place one rafter tie bracket against the face of the header which will face the inside area of the pergola. A small tab in the
bracket sits on the top surface of the header. Eyeball and align the center of the small tab with the line you marked on the
header top surface.
