through the opening area.
2. From inside, mark and drill a guide hole at the center of
the opening area.
3. From the outside, use the guide hole as a starting point to
lay out the installation.
A. Use a T-square to measure 11
13/16
” (30.0 cm) to the left
of the guide hole, then 14
11/16
” (37.3 cm) to locate the
top-left corner of the layout.
