A window frame including a pair of identical frame halves that can be interconnected without fasteners. Two different connector systems are integrally formed with the frame halves, and the frame halves have two possible orientations with respect to one another?a ship orientation and an install orientation. The first connector system releasably interconnects the frame halves in either orientation. The second connector system essentially permanently interconnects the frame halves only in the install orientation?not in the ship orientation.
