Step 1
Assemble Trusses
Building Tip: To aid in the assembly of the trusses, temporarily screw 2x4 blocks to
the floor. There are short 2x4s, that may have an angle on one end, supplied in kit.
1.
Screw (2) two 2x4 blocks to the 12' wide end of the floor at the top corner, see below.
2.
Place two truss legs together. Position the notch in the 2x4s (called a bird's mouth) into the
2x4 blocks. Important: You must have 12'-0" between the bird's mouth. Affix more 2x4
blocks above the truss legs to hold the truss members in place.
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 2x4-90" collar tie between the 2x4 boards. Hold in place with 2x4 blocks. Install
12"x24" gussets to the ends of the collar tie. Glue and nail using 14 nails per gusset.
5.
Turn this truss over and apply wood gussets to the opposite side.
6.
Repeat 2 through 5 to assemble (6) six more trusses. Note: The parts for the last (2) two
trusses are packed in the carton with the porch material.
Do Not remove blocks from floor until completing Step 2.
