This is a long shot, but I an hoping for a 53x41" plexiglass bubble SKYLIGHT. 4.5x3.5ftwould work too.The roofers stepped through and disappeared of the face of the earth leaving me with a hole and roof to finish.. Or larger is OK too. Failing that, I will be happy with a  larger piece of clear plexiglass, or plate glass, to the cover the hole in my roof and still have light in my kitchen. Today's doubleglazed skylights are too heavy for the building.
