Which junction box for 250v receptacle 30A

Which junction box do I need for a 30A 250v receptacle like this:
https://www.homedepot.ca/en/home/p.3...000174855.html

Seems to be deep and the attachments are not standard.
It's for a 5600w electric garage heater.

I would recommend a deep 4" square (1900) box with a mudring.

The flush mount receptacle seems to have these clamp type connectors for the wires. I thought push fit connections were considered bad? I was expecting a screw terminal but these seem different.

The clamp terminals are fine because there is a screw to put pressure on the wire. Push-in terminal on 120v receptacles on the other hand have just a light spring finger that can weaken with time.
