ABSTRACT STAYS A stay for, for example, a window has a channel section for connection to the fame and an arm for connection to the opening window leaf. A linkage extends between the arm and the channel and includes a slider on which is mounted at least one of the links and which slides along the channel during opening and closing movement of the arm. In one embodiment, the slider carries on elongate member which is biased into a position in which the member engages a stop on the channel to restrict the opening movement of the arm. A member can be depressed to disengage it from the slot and allow full opening movement of the window. In a second embodiment a device is provided between the slider and the base channel for selective operation to limit the opening movement of the leaf. This device may be an elongate removable intermediate stop that prevents the arm opening to the maximum extent and limits the opening to a point at which, for example, ventilation is provided but access through the window is not possible. As a second possibility a screw may be provided on an elongate restrictor bar attached to the slider so that when the screw is in an operative position it contacts the stop before the leaf is fully open. A third possibility is to provide a screw on the slider which, when moved to an operative position, engages the slider. 114DO
