1) Allowable loads have been increased 60% for wind or seismic loads; no further increase shall be permitted.
2) LFTA6: To achieve F1 lateral loads, three nails must be installed on each side on the strap located closest to the bend line.
Lateral F1 and F2 load directions do not apply to roof truss-to-top plate installations.
3) 8d common nails may be substituted for 8d x 1-1/2 nails, and 10d common nails may be substituted for 10d x 1-1/2 nails.
4)
NAILS:
8d x 1-1/2" nails are 0.131" dia. x 1-1/2" long, 8d nails are 0.131" dia. x 2-1/2" long, 10d x 1-1/2" nails are 0.148" dia. x 1-1/2" long,
