szomk Enclosures

I am trying to a cheaper alternative case to the following on Polycase. It was recommended to me to look at a website called http://www.szomk.com.cn/. The site is in Chinese, and I can't really tell if there's a watertight, NEMA enclosure that is sized the same as what I am currently using.

I know it's not quite Arduino, but I do have an Arduino inside of my enclosure. Can anyone suggest an equivalent enclosure on this site or perhaps another? Thanks.

EVERY enclosure meets NEMA ratings.
NEMA 1 is open
NEMA 4 is hose directed water
NEMA 3r is rain proof

The quest might Which NEMA rating?
