Installation of stringers
STEP1
Measure the length of the stringer “W” between the cross-beams
(Figure18). The measurement should be perpendicular to the headers.
STEP2
Cut the stringer to size. Use timber similar in size to the existing
ceiling joists.
STEP3
If the joists do not make up the other two sides of the frame, you
need to install one more stringer of the same length as before. On
Figure 18 only one stringer is needed because the ceiling joist
makes up one side of the frame.
STEP4
Position the stringer (or stringers) along the unframed side if the
ceiling opening (Figure19). The inside dimensions of the frame
should be equal to the ceiling opening (see Table 2 on Page 5).
STEP5
In order to install stringers to the headers you should use nails long
enough to go through both cross-beams and enter the stringer at least
1”. In most cases it should be 20d nail 4” long. Square the stringer
and drive 3 nails at each end through the double header. Both
measured dimensions should be within 1/8” to consider them equal.
