Important to note that in the realm of Full-Access/Frameless cabinets, opening sizes are often defined by parameters given for door or drawer front heights. For an example, upon selecting a “Base 3 Drawer” unit we will require that you specify for us a top-drawer front height so that we might automatically calculate the remaining drawer openings. It is also important to note that once a project through Cabinotch’s Full Access portal is “Carted” to your account we will give you a Door and Drawer front list (non-included parts) which have sizes which are calculated based upon the responses you give for this option as well as all options pertaining to “Reveals”.
