## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Exactly what I needed.
  

*by F***R on Reviewed in the United States on 18 April 2023*

I do metal cutting and grinding on a dedicated cart with electrical wiring for a/c power in, outlets, and power on/off switches. I use cable glands with these boxes to keep dust, moisture, etc. out of the enclosures. The typical electrical boxes from the big box stores has too many little holes for metal dust/particles to enter which is not ideal for electrical connnections.
