Starting on back corner measure from the backside of the 2x4 gable frame when marking
the location of the first truss. Continue 24" spacing to other gable. Important: When marking
the opposite wall, place the 'X' mark on the same side of the line so your trusses are parallel
when they are installed.
2.
Install metal hangers to the tie plate with 1-1/2" hanger nails . The opening should line up
with the 'X' mark, the bottom of the opening, flush with the 2x4 tie plate. Detail 'D'.
