Step 1
Assemble Trusses
1.
Screw (2) two 2x4 blocks to the 12' wide part of the floor, see below. The 2x4 blocks should
extend 2" beyond the outside edge of the floor, see detail 'A'. Use 2-1/2" screws provided.
2.
Place (2) two 96" long truss legs together at peak. Important: Bottom of truss legs must
measure 12'-4" as measured from tip to tip. Affix (3) three 2x4 blocks along top edge of each
truss leg. Place middle block 69" from peak, see below.
3.
Secure the tops together with a wood gusset. Apply wood glue between the 2x4 boards and
the gusset. Nail the gusset to the 2x4s with 6d common nails. Use 14 nails per gusset.
4.
Install a 2x4-84" collar tie between the 2x4 boards. Insure collar tie is parallel with edge of
work surface, see below. Hold collar tie from moving with 2x4 blocks. Install 12"x24" gussets
to the ends of the collar tie. Glue and nail using 14 nails per gusset.
5.
Turn truss over and apply wood gussets to the opposite side.
6.
Repeat 2 through 5 to assemble (4) four more trusses.
7.
Assemble (1) one more truss without the 2x4 collar tie and the lower gussets (used on porch).
Do Not remove blocks from floor until completing Steps 2 and 3.

Building Tip: If you are installing the building on a wood floor, temporarily screw 2x4
blocks to the floor as described below. There are short 2x4s, that may have an angle
on one end, supplied in kit. This will insure that all the trusses are assembled the same.
