Frame Assembly
ASSEMBLY NOTE: INSTALLING THE 108938 DIAGONAL STRUT (mounting feet only)
For all frames that include the 108500 mounting feet and rafter legs, complete the following procedure after each rafter
is assembled and attached to the rafter legs and
before
you add purlins to the entire frame. Completing these steps will
help maintain a uniform result when assembling each rafter and the entire frame.
NOTE:
If your building does not include the 108500 mounting feet as shown, skip this page and continue with the strut
installation steps on Page 15.
Complete the following procedure:
With the assembled rafter attached to the top of each rafter leg as previously described, install a brace under
a.
the middle of the rafter and push the rafter up to the height shown on the Front Profile Grid diagram in the Quick
Start section for your building. (Brace is supplied by the customer/contractor. Consult a contractor if needed to
determine the best way to support each rafter during assembly.)
Verify that both rafter legs are plumb and that the rafter is not twisted or leaning toward the front or back.
b.
Measure center-to-center between the tops of the rafter legs to verify that the on-center measurement is equal
c.
to the width of the building. Adjust the brace as needed and use it to help secure the positions of the rafter legs.
NOTE:
If needed, use a strap or rope to keep the tops of the rafter legs plumb until you install the diagonal
struts. See the dashed line in the diagram above.
With the rafter supported and braced in place, install the diagonal struts as described on the next page. Use
d.
assistants to help align the rafter mounting hole with the hole in the strut.
See the Front Profile Grid diagram
in the Quick Start section for the
height of your building.

rafter during the installation of
the diagonal struts.
Verify that each rafter leg is
plumb and secured to the
mounting foot.
Install brace and push rafter up to reach height
of the building. Adjust brace as needed to
account for an uneven site. Consult the Front
Profile Grid diagram in the Quick Start section
for building height.
