1) Attach the nailing tabs to the corner posts
using the 2 sheet metal screws sup-
plied. Secure through the centre of the
top and bottom slots in the nailing tab
and then through the existing holes
in the corner posts.
If there are no existing holes, follow
these instructions:
Position the nailing tab so that the
front face is offset with the front edge
of the corner post (approx. ½"). Cen-
tre the nailing tab vertically on the cor-
ner post.
Figure 12 a.
Drill through the centre of the top and
bottom slots in the nailing tab. Secure
using the two sheet metal screws
supplied. This allows the nailing tab to
slide back and forth for desired framing. Figure
12 b.
2) To determine the final location of the nailing tab you
must first determine the thickness of your finishing mate-
rial (i.e. drywall). This will determine the dimension from
the front edge of the corner post to the nailing tab. Once
the nailing tab is in the desired location, drill through the
centre hole of the nailing tab. Secure with a sheet metal
screw*. Figure 12 c.
* Additional set screws may be installed.
