Need a recommendation for an AP enclosure

Hello /r/Networking

I'm working on an exiting project will use state of the art APs from a start-up company named MIST. If you haven't heard about it, it's all about AI and LBS.

They will be installed on the roof of an open parking lot. We want to protect/conceal them against vandalism mainly. Power will be over ethernet.

The problem is that this company's outdoor AP is HUGE (12.2in x 12.2in x 4.3in), and I'm having a hard time finding any enclosure that is not taller than 6.5", our current legal-limit.

So far NEMA enclosures do not quite fit my requirements. I was thinking in ordering custom-built, but I don't know a good provider.

Thanks in advance for any help given.
