Step 1
Assemble (2) Two Dormer Trusses
Building Tip: To aid in the assembly of the trusses, temporarily tack 1x4 blocks to the
floor. There are short 1x4s supplied in the kit for this purpose. This will trap the truss
parts and ensures the other truss will be assembled the same.
1. Assemble a dormer truss using (2) two 78-3/4" long 2x6 rafters, (1) one 95-3/4" long 2x4
with angle cuts on the ends, and a pre-built saddle. There should be 140" between the notch
in the 2x6s. Hold parts in place with 1x4 blocks. Secure the 95-3/4" long 2x4 with (2) two
2-1/2" deck screws.
2. Install pre-cut OSB gussets over the dormer truss parts
to secure them in place. Apply wood glue between the
framing and OSB gussets. Attach gussets with (2) two
rows of 6d common nails spaced 6" apart.
3. Remove the siding that covers the slot in the saddle. This
will allow the ridge beam to extend through the truss.
140"
4. Turn truss over and install another
OSB gusset in the center of the truss.
Glue and nail. Do Not cut a notch
in the siding.
5. Repeat steps to assemble another
dormer truss. Set these trusses aside,
they will be used later.
