Flush Inset Panels
The flush inset application is an overlay model with flush
inset panels. It is not a separate model.
The flush inset design allows custom panels to be installed
flush with adjacent cabinets. Similar to overlay, flush inset
panels are typically created by combining a ⁄" (19) custom
panel, a .10" (3) spacer panel, and a ⁄" (6) backer panel.
Refer to the illustration below.
For flush inset panels thicker than ⁄" (19), a 90° door stop
may be required to prevent interference with adjacent
cabinets. Refer to the full-scale templates at the end of this
guide.
When installing two units side by side, refer to page 13 for
dual flush inset installations.
