ABSTRACT:
A hatch generally includes a hatch lid frame having a fixed opening defining a perimeter, a lens having a lens perimeter smaller than the opening perimeter such that the lens is insertable into the opening, and a gasket disposed between the hatch lid frame and the lens. The lens asserts a force upon the gasket to sealably secure the lens within the hatch lid frame. A method of securing a lens within a hatch lid frame generally includes inserting the lens into an opening of the hatch lid frame, asserting a force upon the lens to direct the lens in a direction, inserting a gasket between the lens and a perimeter of opening, and de-asserting the force applied to the lens to sealably secure the lens within the hatch lid frame.
