application over standard sized wells which presently come in sizes such as 42 u2033 50 u2033 67 u2033 and the like cover 100 is most preferably slightly resilient to accommodate dimensions that deviate slightly from the standard dimensions as will be further understood herein below domed or elevated body member 110 comprises the majority of surface area and is designed to allow standard casement window 220 to operate freely when cover 100 is in operative position as shown in fig1 consequently in the event of an emergency an occupant may fully open casement window 220 and then enter into the well area defined by well wall 240 cover 100 and building foundation 200 furthermore using the preferred embodiment cover 100 the orientation of hinges on casement window 220 such as whether the hinges are left or right handed is irrelevant body member 110 includes top body member 120 which is generally trapezoidal in shape while generally planar in preferred embodiment cover 100 top body member 120 will most preferably be slightly domed from the edges to the center this slight dome shape ensures drainage of moisture rather than pooling or puddling and also adds to the total load bearing capability of top body member 120 in addition to being slightly domed top body member 120 will most preferably exhibit a slight or gentle slope away from foundation 200 to help direct moisture away from siding 210 and foundation 200 supporting top body member 120 are sides 130 132 134 each which extend in a generally vertical direction sides 130 and 134 have a trapezium geometry while side 134 has the shape of.
