ABSTRACT:
A fixed frame mounted on a housing and a vent frame hinged to the fixed frame. The vent frame is moved between closed and open positions by a single-handle double operator actuated from the interior of the housing. The hinge and operator apply forces to create a continuous water seal in the closed position. The seal and hinge prevent rattle of the vent frame.
