Preparation (cont.)
The side supports should be 10" (25.4 cm) long unless the back
support is thicker than 1" (2.5 cm). If the back support is thicker
than 1" (2.5 cm), determine the length of the side supports by
measuring from the inside edge of the back support to the inside
edge of the apron.
The back edge of the support frame should be located 17-3/8"
(44.1 cm) from the front of the sink. Do not measure from the
front of the cabinet.
