### ⭐⭐⭐⭐⭐ Great price for a standard wet location electrical box
*by R***R on December 11, 2025*

Great price for a standard wet location electrical box. These are about half the price of the ones at the big box stores, which are exactly the same. Why pay more for the same exact thing? If you don't need one right away, they are a better deal on here.
