Topband: Weatherproof enclosure source?

[jan0 at comcast.net]

I'm looking for suggestions for sources for a large weatherproof enclosure,
at least 6 feet wide by 4 feet high and 8 inches deep (supporting a minimum
of seven, 4-inch conduits entering from below), to house the entrance panel
and single-point ground of a new station.  It will need to be metal,
preferably galvanized steel, and will be mounted on the outside wall of the
house.  

 

Has anyone a suggestion for a supplier?

 

Thanks, and 73,

 

Ed N4II.
