n. a non-keyed deadbolt, with a one piece escutcheon/faceplate, typically mounted flush to door surfaces
A door bolt that is flush with the face or edge of the door. For use on a dummy door.
A bolt that is mortised into the edge of a door that will lock either or both the top and bottom of the door. Usually used on a pair of doors so that one door will remain closed or inactive, allowing the other door to lock into it.
The locking devise mortised into an astragal which secures the astragaled door of a pair of doors in a closed position. The flush bolt engages in the sill and the header to hold the door in the closed position.
A bolt mortised into a door that holds the door closed when the bolt is projected, usually into the head or sill of the doorframe. In contrast with a surface bolt, the flush bolt is mounted flush with either the edge or face of the door. Flush bolts are often used to hold the inactive door in a pair closed, while the active door is kept open for regular use. (See Surface Bolt.)
Sliding bolt mortised into the edge of a door or astragal that typically engages into the jamb head and sill to secure the door. Commonly used on the inactive door of a pair.
A bolt that is flush with the face or edge of the door when retracted. Keeps an inactive door stationary.
