Double-aperture apparatus for attaching lock or lockbox to door lever
Apparatus for attaching a lockbox used for retaining a key to a door opened by the key to a door handle and especially a door lever used to open and close the door. The apparatus includes two arms each having a head portion and a bottom portion below the head portion. The arms have an open state in which the head portions are at least partly separated from one another, and a closed state in which two different-sized apertures are defined between the head portions and separately receive the door handle. The arms are positionable around the door handle or removable from such a position when in the open state. The arms are maintained in the closed state and movement thereof from the closed state to the open state is prevented by inserting a shackle of the lockbox through a staple engaged with both arms.
