Decorative End Doors, or Decor Deeors, are designed to be installed on cabinet sides.  While our cabinets have finished sides, many people choose to install these decor doors to give their cabinets a high-end look.
Doors are sized appropriately to be installed directly onto side of face-frame at front of cabinet.  (Use 1/4" shim to adjust decor door at back of cabinet side.)
