Add 2x4 blocks here
to trap the top 2x4.
Step 1
Assemble Trusses
79-5/8" Long Top Member
Building Tip: To aid in the assembly of the trusses, temporarily tack 2x4 blocks to the floor.
There are short 2x4s, that may have an angle on one end, supplied in the kit for this purpose.
This will trap the truss parts and insure that all the trusses will be assembled the same.

Top Gusset
1.
Position a 138" long 2x4 and (2) two 79-5/8" long 2x4s diagonally across the floor. The shorter
2x4s will rest on a flat spot on the bottom 2x4. See Detail 'A' below.
2.
Affix 2x4 blocks around the truss members to hold them in place. Tack a 3" wide gauge block,
in hardware bag, at both ends of the bottom 2x4 to maintain the correct overhang.
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 12"x12" wood gussets to the ends of the trusses, flush with the end of the bottom 2x4.
Glue and nail the gusset. Use 8 nails per gusset.
5.
Turn this truss over and apply wood gussets to the opposite side.
6.
Assemble (3) three more trusses.
Do Not remove blocks from floor until completing Step 2.
