It can be a decorative architectural element, or a combined ornamented/structural item. In the case of windows, the bottom span is referred to as a sill, but, unlike a lintel, does not serve to bear a load to ensure the integrity of the wall. Modern-day lintels may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block sla

thumb|Fusuma thumb|Kin-busuma (golden fusuma) In Japanese architecture, are vertical rectangular panels which can slide from side to side to redefine spaces within a room, or act as doors. They typically measure about wide by tall, the same size as a tatami mat, and are thick. The heights of fusuma have increased in recent years due to an increase in average height of the Japanese population, and a height is now common. In older constructions, they are as small as high. They consist of a lattice-like wooden understructure covered in cardboard and a layer of paper or cloth on both sides. They t

thumb|A trapdoor to a bomb shelter from [[World War II]] A trapdoor or hatch is a sliding or hinged door that is flush with the surface of a floor, ceiling, or roof. It is traditionally small in size. It was invented to facilitate the hoisting of grain up through mills, however, its list of uses has grown over time. The trapdoor has played a pivotal function in the operation of the gallows, cargo ships, trains, booby traps, and more recently theatre and films.

right|thumb|Door with two locks, one in the doorknob and a separate deadbolt A deadbolt or deadlock is a type of lock morticed into a wooden door where a bolt is thrown into the door frame, using a key from either side, to secure the door. It is distinct from a spring bolt lock because a deadbolt can only be opened by a key or handle. The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key, as well as make the door more resistant to fo
