Rough Opening and Net Unit

Prehung door and sidelight units are purchased from Antigua Doors by specifying either rough opening or net unit size.  We have prepared a diagram titled, Measurement Diagram to illustrate the applicable measurements when ordering a prehung unit.  The charts that follow the diagram list the exact measurements in which your prehung unit will be sized depending on the chosen configuration.  Standard sizing is highlighted, with a nominal charge applied when the rough opening or net unit size requires a jamb thicker than 3/4".  Rough opening and net unit sizes that require the actual door to be built outside of standard widths will have an additional charge.
