Review on RVMATE NEMA L14-30P Generator Power Inlet Box - Pre-Drilled, 125/250V 3750/7500W, Waterproof For Outdoor Use by Elliotte Rogers

Always tough to balance, resistance to elements with durability, in this case I would have preferred the box be made of metal.That aside, it is nicely made and ought to do the job as long as it it is not struck on, or by something.The plastic will likely shatter, while metal might just deform and end up being repairable, that is the reason for my preference.

If a metal box gets a bit rusty, there is always the option of a little wire brushing and paint, whereas once plastic gets deterriorated by UV, there is nothing you can do but replace it.
