Review: 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. Review: Great quality, easy to fit! - Really great quality product! I purchased this to mount a Ring Floodlight Camera on the side of my house for the drive. It was really easy to mount and provided a level surface for the ring camera to mount on. The box itself is really high quality metal and feels very sturdy in the hand. Very easy to install aswell and really liked the built in earth screw which made it very easy to wire everything up. ## Features - Provide a junction for conduits or can be used to mount lampholders and lighting systems - Features five 1/2-in knockouts and 16 cu. in. capacity - Includes mounting lugs, closure plugs and a pre-installed ground screw - Die-cast construction and powder coated for corrosion resistance - Product is UL and CSA listed, suitable for wet locations and NEMA 3R rated ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C3YD6HU | | Brand | Sigma Engineered Solutions | | Brand Name | Sigma Engineered Solutions | | Capacity | 16 cubic inches | | Color | White | | Colour | White | | Customer Reviews | 4.7 out of 5 stars 1,734 Reviews | | Finish Type | Powder Coated | | Finish type | Powder Coated | | Global Trade Identification Number | 00031857643850 | | Included Components | Sigma Engineered Solutions 143854WH 1/2-Inch 5 Hole Round Weatherproof Box, White | | Installation Type | Screw-In | | Item Dimensions D x W x H | 10.7D x 14W x 5.7H centimeters | | Item Type Name | Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box, White | | Item Weight | 0.5 Pounds | | Manufacturer | Sigma Electric | | Material | Aluminum | | Model Number | b5b4dfb4-09e3-40da-b716-f01bcab2f649 | | Part Number | 143854WH | | Product dimensions | 10.7D x 14W x 5.7H centimeters | | Specification Met | CSA, NEMA 3R, UL | | Style | Compact | | UPC | 031857643850 | | Unit Count | 1 Count | ## Product Details - **Material:** Aluminum - **Brand:** Sigma Engineered Solutions - **Colour:** White - **Style:** Compact - **Product dimensions:** 10.7D x 14W x 5.7H centimeters ## Images ![Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box - Image 1](https://m.media-amazon.com/images/I/61yLHRT151L.jpg) ![Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box - Image 2](https://m.media-amazon.com/images/I/71cZ1EshuJL.jpg) ![Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box - Image 3](https://m.media-amazon.com/images/I/71fiksjteHL.jpg) ![Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box - Image 4](https://m.media-amazon.com/images/I/61NsO6teZcL.jpg) ![Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box - Image 5](https://m.media-amazon.com/images/I/61np3i+LF0L.jpg) ## Questions & Answers **Q: How many threaded plugs does it come with?** A: It has 5 holes, and 4 plugs.
