I. Marking
According to the footprint and outer dimensions of the cabinets, do the following:
1) Decide where to drill the mounting holes.
2) Measure mark dots with a tape.
3) Draw two lines parallel with the reference and 720 mm (28.3 in.) away from each
other with an ink fountain.
4) According to the design, mark the position of a mounting hole on one of these
two lines. Based on this mark, mark the position of other mounting holes.
5) Verify marking and sizes to prevent mistakes.
Figure 8-7 and Figure 8-8 illustrate the mounting holes and cabinet feet layout
for a single and two cabinets respectively.
