The base unit has a face frame and skeleton frame.
A number of joints can be used to fasten the stiles and
rails together, as shown in figure 5-9. The stiles are
always mortised and the rails are always tenoned (fig.
A typical full-size wall unit is usually 12 inches
deep and 30 inches high (fig. 5-11). A wall unit above
a range is 18 inches high. Above a sink, it is 22 inches
high, while over a refrigerator, it is only 15 inches high.
The number and spacing of shelves depend on the
purpose of the cabinet. Shelves may be fixed or
adjustable. Shelves are usually spaced from 3 to 12
inches according to the customers wishes.
The wall unit, like the base unit, has a face frame on
which to fit and hang doors. These face frames are
usually made of 1-inch by 2-inch solid lumber. The
actual size is 3/4 inch by 1 1/2 inch.
An allowance is made on the back edges of the end
pieces for scribing. Mounting strips must be included
in the wall units. Screws are driven through these strips
to hold the cabinet on the wall.
