Make a rough opening to the size as required in table 1 ensuring that the dimensions of the
diagonals of the frame are the same as illustrated in Figure 14.
A. For Rough opening without joist removal (Figure 14)
• Locate headers in front and rear of the
opening as shown in Figure 14.
• Check for squareness by making sure
that diagonal measurements are
within

.
• Secure using (3) 16d nails into each end
of the Header.
