The frame is the front of the cabinet box where the door attaches.
Framed cabinets are available as a standard-overlay or as a full-overlay (see 'Kitchen Cabinet Terminology' below).
Frameless cabinets have no front frame, the door attaches directly to the box itself.
The advantage to frameless cabinets is you end up with a little more interior space and larger drawer boxes.
The disadvantage is that they have zero tolerance if any adjustments need to be made.
Framed cabinets are more forgiving and much easier to install.
