I like the BUD industries NBF series NEMA enclosures. They come in a variety of sizes, and you can get them with clear or solid door. The door is important. I would be reluctant to use a box with a screw on cover. I think you would need to drill holes for the conduit using a hole saw. No big deal.
They are available direct from BUD industries, or many models are available from Amazon, some are even Prime.
