TayMac MM420C 1-Gang Nonmetallic Extra Duty Weatherproof In-Use Horizontal/Vertical 16-in-1 Standard Cover, 2.75 in, Clear

I’m very impressed with the TayMac MM420C 1-Gang Extra Duty Weatherproof In-Use Cover. It’s built with strong, high-impact polycarbonate, so it feels very durable and able to handle harsh outdoor conditions without cracking or fading. One of the best features is the “in-use” design—you can keep something plugged in while the cover stays closed and protected from rain. The 16-in-1 configuration makes it super versatile and compatible with different outlet types, including GFCI setups. Installation was quick and easy thanks to the keyhole mounting system, and it can be mounted either horizontally or vertically depending on your setup. The clear cover is also a nice touch—you can easily see the outlet status without opening it. Overall, it’s a reliable, heavy-duty solution for protecting outdoor electrical outlets. Highly recommended for anyone needing a safe and durable weatherproof cover.

Installed this over a 1-gang exterior box and it’s exactly what you want for an in-use cover. The housing is solid, seals well, and doesn’t feel like brittle plastic that’s going to crack the first cold winter. The horizontal/vertical mounting flexibility is a big plus, and there’s plenty of room inside for cords without forcing the cover or stressing the seal. Gasket fits properly, screws tighten evenly, and everything lines up the way it should — no fighting it during install. Rated Extra Duty for a reason. Once it’s mounted, it stays closed, stays sealed, and does its job. Costs a little more than the cheap covers, but this is one of those “buy it once” items that’s worth it. Would absolutely use these again.

I’m a 64 year old woman who knows only enough about electrical work to shut off a breaker and change an outlet. I became a little concerned about purchasing this cover after reading a few reviews from people who said they had difficulty. I’m glad I purchased 2 of them anyway. They come with everything you need, including parts you can change out to fit your outlet or switch. It’s easy (with a little force) to push the hinge pin out and move it to either the top or side, depending on your needs. After installing the first one I learned that it’s better to start your screws and THEN slip the outlet cover over the screws before tightening. Those with more experience than me would say “duh” to that since it’s quite obvious the holes on the box are made for that, but I wasn’t that bright the first time around. Just thought I’d mention it for others like me. Very simple, took little time, and there’s a nice tight fit that appears to be good and waterproof. Recommend and will buy again.

Does the job, and is deep enough to even hold a usb charger cube. The only drawback I see is that it only is capable of opening on one side. I would have liked to be able to switch the hinge to the opposite site (there are some that allows this). It was easy to install and you don't have to completely pull out the socket to install the cover, becuase it has a slotted opening that allows you to slip it over the existing screws.

Exactly what I needed without confusion.

Fit perfectly, install easily. Water and rain proof and stays shut.

​This weatherproof outlet cover is absolutely fantastic! The deep, extra-duty "bubble door" design is exactly what I needed. It provides a generous amount of interior space, which allowed me to easily insert a bulky smart Wi-Fi plug to control my outdoor lights right from my phone. ​Unlike standard flat covers, this one shuts completely and securely even with the larger smart plug and heavy cords attached. It seals out rain perfectly and keeps everything dry and protected from the elements. If you want to use outdoor automation or smart home plugs on your patio or exterior walls, this is an absolute must-have!

It’s excellent, fits perfectly and is easy to install and work perfectly

Needed a replacement for my septic tank plugs. Easy to replace and now protected.

Excelente!

A good solution for a more robust child-proof electrical outlet. Most AU outlet plates will be too big to fit inside so some DIY modifications are required. I recommend using low-profile outlets to maximize cable clearance.

excelente buena calidad

Used to make sure my freezer is never unplugged by my infant. It works great and now I never have to worry that the cord was tugged on because the clear box allows me to see inside. Way sturdier than other babyproofing outlet covers.
