The RV Park box I have is lockable, but it's rather large, since it has circuit breakers in it, and a 14-50, TT-30 and a 120V 20A GFCI outlet in it. There are holes on the lower left and right of the cover/body to insert a rod or locks.
Here's a link for a similar model, much smaller, and it is lockable:

By the way, I'm an electrical contractor with nearly 30 years experience in Washington state. Feel free to ask me any electrical questions.
Good luck!

Are you looking to secure it when you're not using it or also when you're using it? I used to live in a townhouse complex with carports. I had a weatherproof box installed with a Nema 14-50 plug. When you're not using it, the box closes and you can attach a small padlock to keep it closed. When you're using it, it gets a bit trickier because the cover doesn't close all the way.
Here's a link to my solution. It's at the bottom of page 1. It worked pretty well. I usually just kept the UMC plugged in all the time and locked to the box.
Will the UMC fit when the cover is closed?

Here is a much smaller installation, with a locking slot on the lower right I did at my house.
Sorry they oriented sideways.

Here is the solution we put together at my office. It captures the mobile charging adaptor so it can't easily be stolen.
I would maybe put a rubber grommet on the bottom of that box where the cable is coming out. But looks like a great idea for outside!

Here is an inexpensive version with locking lid, $30 at Home Depot. Surface mount with knockouts on both sides, bottom and back.

You might be required to put an additional means of disconnect, like this within line of sight, since you are defeating the regular means of disconnect (the plug). The locks are supposed to remain open when in use if no other means of disconnect are within line of sight. The locks on boxes are mostly meant to protect people servicing the circuits. This prevents someone from being electrocuted because someone else energized the circuit. More info here.

No way a Tesla 14-50 adapter fits under that lid when it is locked.
14-50 is not much different from a dryer plug, so unlikely to need a separate shutoff other than circuit breaker. I wouldn't/didn't even pull a permit for such a thing.
I like this.

Only thing is you don't have the UMC with you if you need it.
Most jurisdictions require a permit for anything short of a direct replacement of an existing device. Any new circuit or circuit extension generally requires a permit pull in those jurisdictions where separate electrical permits are required.
Hi Dane, I really like your box setup. I was wondering how did you cut a hole to fit the wire in? It looks really clean.
Just joined this forum but have been lurking/researching for an EV solution for my office but didn't know what would work as it's exposed and outdoors. Obviously, was worried about theft / security but was able to come up with a solution based on a lot of what I saw here.
Just wanted to give back to future users to see what can be created.
I came up with the following solution which has been working great. Box is 24in x 24in. Locks easily.

That’s a pretty interesting setup. I’ve come across dozens of HPWCs mounted in public locations at this point and never thought of putting one in a giant metal box.

Not sure what the point of this is, unless you're locking the entire cable in the box when not in use. The wall connector is already securely mounted.
