A.2.4 Levelling Cabinets
I. Positioning Cabinets
After finishing marking, move the cabinet to the planned location with its feet aligning
with the corresponding feet marks.
II. Adjusting Cabinet Feet
Place two horizontal rulers perpendicular to each other on the top of the cabinet to
check that the cabinet is straight. Adjust the cabinet feet with a spanner to have the
cabinet perpendicular to the ground. Fasten the retaining nuts on the feet to have the
retaining nut closely meet the downside of the cabinet. Figure A-10 shows how to lock
cabinet feet.
