Abstract
A hingeless ventilator comprises a frame defining two openings surrounded by a seating rim, which is surrounded by a door recess. A pair of upright sleeves is disposed between the openings, and each upright sleeve defines an exterior track surface. A door is disposed to face the outer surface of the frame and has a main body configured to be selectively positionable to cover and uncover both of the openings and defines a lip surrounding the periphery thereof and extending generally perpendicularly to the main body. Two door struts connected to the door extend through the frame openings and hold a handle that has rollers that are biased against the exterior track surfaces of the sleeves.
