RVGUARD NEMA 5-15, Black 15 Amp Flanged Inlet 125V, Shore Power Inlet Receptacle with Waterproof Cover, 2 Pole 3-Wire, Straight Blade（Black ETL Approved)

A few issues with this that make it mediocre at best. The hole size needed for install is 2, not the 1.75 the pictures and description in the listing seem to suggest. Even the instructions that came with the plug state a 2 hole is needed. Itd be nice if the listing was updated to not cause confusion. This plug is absolutely not waterproof. At best Id call it mildly water resistant. I installed this on a horizontal surface on a camper trailer so the receptacle is facing upwards. First issue is that the plastic base where the prongs are attached has a gap around the entire circumference of the receptacle that is very much open and allows water to pass through. Secondly, the cap that blocks the receptacle when not in use is not the tightest fit, so water can absolutely make its way in. While driving in wet conditions, a LOT of water made its way through the receptacle and into the battery compartment on my camper trailer. Definitely not a good place for water to be. I went to town with some silicone sealant and have a more water resistant receptacle now, but Im still not convinced it is going to be as tight as I need. So long story short, if you are planning to mount this horizontally or otherwise in a place that will see a fair amount of moisture, Id look for a different plug. If youre going for a vertical mount with little to no moisture around and definitely wont be using the receptacle during adverse weather, then its fine.

Not bad for the cost.

Worked perfectly on my camper, I now have a designated 120v plug for my oil filled heater that keeps us toasty.

Very sturdy and durable design. Simple installation. Great for a shop or shed, RV, Trailer, or just anywhere you need a plug that you would like to keep waterproofed.

The product meet my expectations

Great product

The insert is 1.875. The instructions call for a 2 hole saw to install, but that leaves about 1mm between each of the mounting holes and the main hole, and requires precise centering to mark them. It also leaves less room for the gasket to protect moisture from getting in the hole. For the best fit, drill a 1 7/8 inch hole (if you can find a hole saw that size). It makes a snug fit, better mounting security, and less room for water to get in the holes.

I generally use a different brand, but decided to give this a try. Easy to install. Im a little skeptical about the dependability of the cover flap, but so far it is working well.

I installed mine in the wall of a garden shed. Made it easy to power my shed with my solar generator.

I needed a simple way to put electric service into my metal shed. This plug worked perfect
