Just what I need for my Gheenoe mini console. Comes with hardware. I did not check whether the screws are made of stainless steel. The included jacks are rubbish so I didn't use them. Weather protection as expected. This model does not have a large seal as it is part #12VRC. Marinco also sells the 12VRC.PG with a full seal. I limited the circuit to 10A but I think you can increase it to 15A. It has a twist-to-lock feature, although not many 12V plugs have this feature. Overall I would buy these again.
