APPENDIX - Framing A Rough Opening Parallel To Ceiling Joist
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 18.
A. For Rough opening without joist removal (Figure 18)
• Locate headers in front and rear of the
opening as shown in Figure 18.
• Check for squareness by making sure
that diagonal measurements are
within ⁄.
• Secure using (3) 16d nails into each end
of the Header.
B. Rough opening with joist removal (Figure 19)
• Install temporary support boards
spanning both sides of joists to
be removed.
• Remove joist at length to allow for
double headers to be installed on both
ends of opening.
