Security doorstop assemblies configured for securing a door closed or partially closed. The doorstop assemblies include a detent (e.g., arm) assembly attachable to a wall proximate a header of a doorframe associated with the door. The detent assembly includes means for allowing movement of the detent assembly between an inactive position, in which the detent assembly is proximate the wall and out of the contact with the door, and an active position, in which the detent assembly is remote from the wall and oriented to arrest the movement of the door as it is being swung open. Methods for securing a door using the doorstop assemblies are also disclosed.

Window opening control device assemblies including a sash restrictor and a restrictor cover, fenestration units including the window opening control device assemblies, and related methods. A restrictor cover is provided to substantially enclose the sash restrictor such that the sash restrictor is protected during shipping and installation of fenestration units using the sash restrictors.
