FRAMING THE ROUGH OPENING

Double Headers
STEP 1. Measure the header length “H” between
the uncut
joists as shown in Figure 15.
STEP 2. Cut 4 headers this length. Use joist-sized
lumber.
STEP 3. Place one of these headers against the end
of the cut joist(s) as shown in Figure 16. It
must fit snugly between the uncut joists.
Hammer it into position if necessary; if it is
more than 1/16 inch too long, trim it. If it
is more than 1/16 inch too short, cut
another piece.
STEP 4. Square the header to the uncut joist and
nail the header to the end of the cut
joist(s) with 3 nails (16d) as shown in
Figure 16.
STEP 5. Check header for squareness then drive
3 nails (16d) through each joist into each
end of the header as shown in Figure 16.
STEP 6. Place a second header against the first
header and nail it to the first header with
3 nails (16d) between each joist as shown
in Figure 17.
STEP 7. Drive 3 nails (16d) through the joists into
each end of the second header as shown
in Figure 17.
STEP 8. Repeat steps 3-7 to install headers at the
opposite end of the opening.
STEP 9. To frame the other side(s) of the rough
opening, go to “Installing Stringers” on
