It’s built with strong, high-impact polycarbonate, so it feels very durable and able to handle harsh outdoor conditions without cracking or fading.

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.

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.

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. ## Frequently Bought Together - TayMac MM420C 1-Gang Nonmetallic Extra Duty Weatherproof In-Use Horizontal/Vertical 16-in-1 Standard Cover, 2.75 in, Clear - SIGMA ENGINEERED SOLUTIONS 14250 Metal Electrical Outlet Box, Weatherproof, Easy Mount Plug and Receptacle Protector, Gray, (3) 1/2-Inch Holes, 1 Gang Box - Leviton W5320-T0G 15 Amp, 125 Volt, Weather and Tamper Resistant, Duplex Receptacle, Grounding, Side and Quickwire, Gray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/25843208-mm420c-1-gang-nonmetallic-extra-duty-weatherproof-in-use-horizontal](https://www.desertcart.tn/products/25843208-mm420c-1-gang-nonmetallic-extra-duty-weatherproof-in-use-horizontal) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-14*
