<p>A restrictor device for limiting the degree of opening of an openable closure. The restrictor device has an arm (10) with a mounting plate (12) to pivotally mount the arm to either the closure or the frame on which the closure is mounted. The arm (10) is furthermore coupled to the closure or the frame as the case may be by a slideable element (16) to which the arm is pivotally coupled by pivot (15). A movement restricting device is incorporated in the slideable element (16) whereby the movement of the slideable element can be selectively restricted.</p> |
