## Description

While-in-use outdoor cover. Extra-duty rated. 16 in 1 interchangeable plate configurations.

Review: Excellent outdoor outlet protection - 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.
Review: Heavy-duty, well-sealed, and easy to work with - 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.

## Questions & Answers

**Q: Would a nightlight fit in this?  I’m tired of my toddler running off with it.**
A: Yes it can fit inside but Remember There are many size of nightlight, Good luck!

**Q: I'm confused about "mounting hardware". I'm just trying to replace a snap-on cover.  Would this unit be able to just snap on without hardware?**
A: I think you're asking if the clear plastic "cover" which is part of this whole exterior outlet cover package will simply snap onto your current outlet cover plate.  The answer to that question is "No."  The clear plastic cover which is part of this product does not snap on.  Rather, it is attached with a plastic pin which must be inserted through a hinge on the cover plate and the clear plastic cover.  However, this product includes all the mounting hardware you would need to replace your entire current exterior outlet cover and the installation is quite simple.

**Q: How much does it stick out from wall?**
A: Mine sticks out 3 inches

**Q: Can you turn the faceplate from 12 to the 9 o'clock position so the outlets can be mounted sideways (=)o(=) with the box hinges on top?**
A: Manufacturer states VERTICAL mount. Hinge is molded on the top only.
