High quality outdoor electrical box

Perfect for mounting outside floodlights or cameras. Price is much better than both of the big box stores in my area. High quality at a reasonable cost.

Sturdy and Reliable for DIY Projects

I've been using this for my recent electrical DIY project, and it's been a solid choice. The material feels robust and dependable, which is exactly what I need when tackling home improvements.One thing I really like is how easy it is to work with. The five-hole design provides ample flexibility for different wiring configurations, making my task much simpler. It also has a clean, white finish that blends well with my home's interior, a small detail but one that adds a professional touch to the work.The only minor downside is that the paint can chip if you're not careful during installation. However, this is easily avoidable with a bit of caution. As someone who enjoys taking on DIY projects, I find this round box to be an excellent addition to my toolkit. It holds up well under various conditions and simplifies the wiring process significantly.

Great Product - Recommended

This is a well-engineered device that replaced an older one. Unlike the previous unit, it came with a super high-quality finish that matches the woodwork and will likely last a very long time. Easy install. Highly recommended.

A solid fit for ring floodlight Pro

A used this to mount the Ring flood light. This is my first electric project in the US, which went smoothly with this quality product. It fits perfectly. It's sturdy.
