1.  Using enclosed Overhang Measurement Tool, measure counter 

overhang in center of location where you plan to mount extension.  Place 

overhang tool under overhang with dimension lines facing upward.  Slide 

tool forward under overhang until it touches cabinet side (Figure A).  Note 

which line the edge of overhang comes closest to.  You may have to round 

off, depending on your unit.  Record corresponding letter for this dimension 

line (for example:  If overhang measures 7/8", record letter "C").

If you choose to use a ruler, measure and record the counter overhang.
