The 8 Best Plastic Outlet Box Covers (2023 reviews)

We are personally inclined towards enerlites plastic outlet box cover, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. It protects outlets from outdoor elements such as rain, mud, dirt, and snow. It comes with all required mounting screws and a foam gasket to place between your electrical box and the back plate. It is compatible with enerlites usb outlets, guide light outlets, and any standard decorator outlets or switches.

The ones that can open vertically and horizontally have two sets of hinges, one set on top and one down one side and you get to choose where you put the hinge pin to either allow it to open vertically or horizontally. It includes a thick gasket to help it stay waterproof. The screws that come with the box are very soft metal and the Philips head on them will strip out very easily. It is great to have the case a bit larger to hold larger connectors.

Why We Like This:

Best For outside plug: Greenfield Plastic Outlet Box Cover

Buy on Amazon

If you want nothing but the best reliable cover, then greenfield plastic outlet box cover is the one you should definitely consider, as it manages to bring a lot to the table. It’s more of a weatherproof cover when not in use. It is perfect outdoor cover for the style. It is spring loaded and will stay tightly sealed if nothing is plugged into it. The cover is metal and has no flex, which seals moisture out better. It will rust when exposed to constant salty air. It has a spring action that will keep it closed. This is easy to install and gives the appearance to be water repellent. It will add more colors in the future.

Why We Like This:

Best With Switch: Greenfield outside Outlet

Buy on Amazon

This cover is quality made but requires a box with four mounting holes two for your device and two for the cover all on centerline. They snap shut and protect the outlet from water. It comes with a cheesy thin foam seal. It has a blacker gasket in the cover and another to seal against the receptacle box. It closes tight and weather resistant.

It is made to cover newer rectangular outlets, not the old style where the plate screwed on at the middle. They offer you a modicum degree of protection and that is all. It's a little big for the spot installed, but it's a quality cover and keeps the moisture away from the outdoor outlet, which was a problem before.

Very sturdy, waterproof outside outlet cover that was easy to install
Takes two hands and the spring is strong
Easy to install, clean look and good snap shut

Best With knockout: Sealproof Outlet Box

Buy on Amazon

The sealproof outlet box should be able to handle its purpose and duties with ease. This is a very nice looking, low profile cover that just looks so much better than the typical "In Use Bubble Cover" type. This one is on pool deck for a light fixture above it. It is made of a durable polycarbonate construction. It comes with plates to fit all receptacle types.

The traditional outlet covers stick out very far, this is perfect for a location where you want it to hug the wall. This is for an outlet that you only use occasionally and then remove the plug and close the cover. This is made as an outlet cover, not to be used with a plug or wire leaving the box. These are well protected and looking great.

Best For additional Outlets: Sealproof Plastic Outlet Box Cover

It can acommodate switches, duplex receptacles either square or rounded, or large outlets. It can be used on a covered patio to cover fan switch & outlets. Whether you are installing a light switch or a thermostat, this works great. The larger size allows heavy duty outdoor cables access and still allows the cover to close.

This works great, has every imaginable cover for any mainstream outlet or switch included and the gasket to seal the bubble top to the bell box is part of the bubble top. It allows the room to allow for full closure of the cover and therefore keeps the water out well. The cover is closed and sealed per instructions and there should be no issues.
