Step 1
Assemble Roof Trusses
1.
Locate a 2x4 -12' board,
with angle cuts on both ends
, to be used for the truss bottom.
2.
Position 105-3/4" long pre-cut 2x4 rafters on the 12' board.

6.
Install wood gussets to secure truss
parts in place. Apply wood glue be-
tween gussets and 2x4s. Secure top
gussets with (12) twelve 6d common
nails. Secure the lower gussets with
(16) sixteen 6d common nails.

8.
Repeat process to assemble (6) six more trusses. Do Not remove the 2x4 blocks around
the perimeter of the truss until the gables are assembled in the next step.
Wood Gussets
7.
Turn truss over and apply wood
gussets to the opposite side of the
trusses.
3.
Temporarily tack 2x4 blocks,
packed in kit
,
around the truss members. This will insure
that the trusses are built exactly the same.
4.
Position a 2x4-17-1/2" block at the ridge.
5.
Position a 16-3/4" long 2x4 gable stud
at each end of the truss.

Important:
To insure the proper overhang, insert a
11-1/4" long 2x3 gauge block (GB) on each end. Butt
the 2x4 truss bottom against the block. Mark this end
of the trusses with an 'X' mark. When you install the
trusses later, install all the trusses with this end on
the same side of the building.
