8.2.4 Adjusting Cabinet Feet
After finishing marking, move the cabinet to the planned location with its feet aligning with the
corresponding feet marks.
Then follow these steps to adjust cabinet feet, ensuring the cabinet is sturdy, as shown in
Figure 8-10:
1) Place two horizontal rulers perpendicular to each other on the top of the cabinet
to check that the cabinet is straight.
2) Adjust the cabinet feet with a spanner to have the cabinet perpendicular to the
ground.
3) Fasten the retaining nuts on the feet to have the retaining nut closely meet the
downside of the cabinet.
4) Repeat the steps to install other cabinets, if there is any.
