Excellent sealing for outdoor use

5 out of 5 stars

Excellent sealing for outdoor use
I’m using this outdoor electrical box to protect connections outside, and the sealing is very solid. The lid closes tightly and the gasket does a good job keeping moisture out. We’ve already had rain and humidity, and everything inside stayed completely dry. The plastic feels thick and durable, not flimsy. It fits extension cords and connectors well without forcing them in, and the cover still closes properly. Installation was straightforward, and once it’s closed, it feels secure. If you need a weatherproof box for outdoor electrical connections, this one does exactly what it’s supposed to do. Very satisfied with the sealing quality.

    Really well made, sturdy product, and easy to set up. I really like how robust the latches are. It seems like the level of water protection is really good.I would recommend getting a size larger than you think you need for your power supply strip to leave enough room for routing cords. The cord pass through holes take up a little room on the interior as well which I didn’t take into account when I ordered the medium size. Their customer service is amazing though and very responsive. They helped me determine the large size would work better for my power strip and sent one directly to me. I highly recommend this product.

    Little tight with amazon smart plugs

    Reviewed in the United States on February 10, 2026

    Color: BlueSize: 1 PackVerified Purchase

    Keeps the water away from your electricity. So its working as intended. Just wish the unit was about 2 inches wider. Works well when you just have to plug in, but when you start to add some smart plugs in the mix. It gets a bit difficult and you loose room fast.

    Key note only 6 inputs/output in the case. Really needs 7 so you can use all 6 plugs on your power strip.

    Easy to use without 4 smart plugs jammed in
    Case thickness is good
    Waterproof sealed
    Needs 1 more input/output

    Decent but not the best out there

    Reviewed in the United States on November 18, 2025

    Color: BlackSize: 1 PackVerified Purchase

    Lasted thru two good down pour rains so far without leaking. Rated 4 stars due to the slots where the cords come in/out needs to be larger to accommodate the thicker cords of a heated pet house and heated water dish. I do not think it will last all winter but for the price it is so far doing it's job.

    Nice look for outdoor matching traditional stucco color

    Reviewed in the United States on January 2, 2026

    Color: AlmondSize: 1 PackVerified Purchase

    Great box and matche stucco. This assisted with the clean install for our permanent lights to hide cords by the eave outlets. The two holes on the back allowing for hooking it to a wall was very big and sturdy.

    I did need to provide my own screws to hook onto the wall but it was no issue.

    しっかり防水。サイズに注意。

    Reviewed in Japan on August 22, 2025

    Color: BlackSize: 1 PackVerified Purchase

    軽量で作りも良いです。防水性もしっかりしています。
    配線を出す部分のゴムの防水キャップでケース内が狭くなっているので内寸には注意が必要です。商品画像にあるように出っ張りのある位置と無い位置で内寸表記が２つあります。私は自分のミスで見誤って入れたかった予定のものが入りませんでした。。
    ケース内を広く作るか外観をスマートに作るかなのでどちらが良いとは一概に言えませんが、個人的には内側への出っ張りが大きすぎて外観に対して中のスペースが狭いかなと思います。
    ちゃんと入れたいもののサイズと比較して間違えなければ問題ありません。安くて良い商品だと思います。
