A selfbolting door is called as such because of its special hinges that permit the panel leaf to move laterally so that the door itself becomes a giant bolt for better security result. The selfbolting door principle can be used both for hinged doors as for rotating doors, as well as up-and-over doors (in the latter case, the bolts are then placed at top and bottom rather than at the sides).
French doors are derived from an original French design called the casement door. It is basically a double-leaved door with large glass panels in each door leaf, and in which the doors can swing both out as well as in. French doors traditionally have a moulded panel at the bottom of the door.
Dutch door or stable door; the top half of the door operates independently from the bottom half.
Garden door Similar to a French door; the hinge is next to the adjacent fixed door and the latch is located at the wall opening jamb. Typically only one door is operable. More secure than the French door.
