ABSTRACT:
A control device is disclosed for selectively displacing two drive rod drivers which are coupled to drive rods of a window or door. The device includes a housing having a guide path defined therein for slidably receiving two drivers. The handle includes a turning member which is directly engaged with one driver and the device includes a clutch which is selectively engageable or disengageable between the two drivers so that, with rotation of the handle member, either both or one of the drivers may be moved along the guide path in the housing.
