I am having trouble locating good dealers to supply the above item (Lowe's seems to carry just one size).
We have several old-fashioned awning-style windows let into our concrete foundation that are relatively close to grade.
I would like to dig out a shallow well around the foundation, surround with a steel corrugate semicircle, fill with gravel, and then cover with a plexiglass or polycarbonate bubble.
Despite multiple tries at google, I haven't found many dealers of such on the Internet.
Any suggestions?
Thanks
