Hidden Doors are most often found in the walls, floors and ceilings of homes.

They can open inward, outward, upward, downward, sideways and the technology of today allows us to build automatic or electronically operated hidden doors that lock, unlock, open and close at the push of a button!

Hidden Door Hinges > are needed for some but not all doors.  Heavy Duty Doors require Heavy Duty Hinges to bear the load without sagging.
