### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Sturdy and Adjustable Two Gang Device Box
  

*by D***D on Reviewed in the United States on July 16, 2024*

I recently used the Southwire Two Gang Device Box for a home wiring project, and it did not disappoint. The adjustable depth feature was incredibly handy, allowing me to fit the box perfectly into the wall without any hassle.The construction is impressively sturdy, which gave me confidence that it would hold up well over time, even with heavy-duty use. It's also very accommodating for different types of wiring, making the installation process much smoother.One thing I particularly liked was how secure the box felt once installed. It didn’t wobble or shift, which is a big plus when you’re dealing with electrical components. The gray color blended nicely with the rest of the installation, maintaining a neat appearance.If I had to point out a small drawback, it would be that the adjustment screws could be a bit more accessible, but this is a minor issue given the overall quality. For anyone tackling a similar project, this device box is a reliable choice.

    Fantastic product.
  

*by S***Y on Reviewed in the United States on August 30, 2024*

I had a ceiling fan box pull out of its place. This product is designed for installing without further damage to your ceiling. It works great! The attachment screws are a little tricky to get at directly. I used a nut driver at first then a screw driver bit to finish and tighten. The metal reinforcement makes it real sturdy. I love that there are bolts with nuts to attach your light fixture. The nuts are nylon locknuts and will never come loose. Installs easily and fast.I highly reccomment this product.
