A drain is a channel, conduit, or pipe designed to carry away or channel superflous liquids for disposal or reclamation.

A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges like the elbow joint.

A mullion is a slender vertical member that forms a division between units of a window, door or panel. A mullion may include a heating element or wire that is activated to keep moisture and frost from forming, for example on the exterior or glass door of a refrigerator or freezer.
