An improved hopper vent is provided which includes many novel features. The hopper vent includes a removable sash window that is removable from the interior side of the hopper vent. The removable sash window is spring loaded into the frame of the hopper vent and is injection molded for easy manufacture. The hopper vent also includes a removable screen which is also removable from the interior side of the hopper vent. The hopper vent also includes a pivot system to allow the removable sash window to pivot open instead of rotating open like in previous, hinge-based systems. Also, the hopper vent includes a dam system which prevents water from draining to the interior of the hopper vent. The dam system includes a front riser to prevent water from draining to the interior of the hopper vent and a drain, such as weep holes or a gap between the frame and the screen of the hopper vent, to allow water to drain to the exterior of the hopper vent. The removable sash window of the hopper vent is also fixedly positionable at a plurality of different openings.
