Typically, stocked cabinets are available in extremely limited sizes, and while most cabinets can be found in 3 inch increments, some stock cabinets might be available in 6 inches increments. This is important when it comes to the overall layout of your kitchen remodel, because stock cabinets happen to be mass-produced to the same size and specifications with no relation as to where they go. You will usually need fillers and end panels to create a finished look when using stock cabinetry. The end of each cabinet that is exposed, on both the top and the base cabinets, will need to be finished to match the front of the cupboards. This will include cutting and fitting finished panels onto the cabinet carcass itself. Keep in mind that if you are running the cabinets wall to wall, then finishing the ends is not important considering that the wall will hide the ends.
