Face Frames

Here is an example of a seam (the thin verticle line to the left of the hinge) between two stock cabinets that have face frames.  Since each cabinet is made independently, they each come with their own frame.  That means when you put them together in an assembly, you have to butt the two frames together creating a seam.

When building custom cabinets you can make the face frame independently of the cabinets and apply one frame, without seams to an entire run of cabinets.
