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.

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. A
minor change in rafter tail 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.
The rafters may be spaced apart 12” or 16”. 12” rafter spacings will shield sunlight longer in the morning as the sun rises in the
sky and earlier in the afternoon as the sun starts to sink in the sky as compared to using 16” spacings. Here, we assume that you
selected 16” spacings for the rafters. Adjust the mark location if you choose 12” rafter spacings.
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. Alternatively, you may wish to use 12” centers if you want the sun light shaded for longer periods.
5.
Separate the two headers by removing the clamp.
