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: Solid build, Easy install, lots of options. - Didn't realize the flood lights I ordered weren't going to mount on a deck without a box, so I quickly settled on these. Pros: * Looks great, feels very sturdy. * No sharp edges, & White is way better looking than bare metal. * Great size, with plenty of room inside to store wires & wire-nuts. * Fit my fixture, & fits at least 2 fixture sizes, as there are 2 sets of screw sockets to choose from. * Easy to mount to outside wall, or deck. No need to cut a hole to recess it into. Yay! * Plenty of choices on how to feed the wire in, & out, if need be. 4 threaded side holes, & 1 Back hole, with 4 little screw in plugs to keep critters & the weather out, when not in use. Cons: * None for me, but if you need it to go into a recessed hole, this is probably not the one to choose. The mounting tabs will surely get in your way. You may think there's not much difference between one electrical box and another, but there really is. This one is very nice compared to all others I've used. (a Lot). That coating is way nicer to your hands, too. No sharp edges on mine. Thanks designers. : ) ## Features - Features five 1/2-in knockouts and 16 cu. in. capacity - Fits standard 4-in round weatherproof box covers (with 4.1885-in diameter) - Provide a junction for conduits or can be used to mount lampholders and lighting systems - Die-cast construction and powder coated for corrosion resistance and includes a pre-installed ground screw and closure plugs - Product is UL and CSA listed, suitable for wet locations and NEMA 3R rated ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C3YD6HU | | Best Sellers Rank | #20,376 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #55 in Electrical Boxes | | Brand | Sigma Engineered Solutions | | Brand Name | Sigma Engineered Solutions | | Capacity | 16 cubic inches | | Color | White | | Customer Reviews | 4.7 out of 5 stars 1,834 Reviews | | Finish Type | Powder Coated | | Global Trade Identification Number | 00031857643850 | | Included Components | Sigma Engineered Solutions | | Installation Type | Screw-In | | Item Dimensions D x W x H | 2.26"D x 5.5"W x 4.2"H | | Item Type Name | Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box | | Item Weight | 8 ounces | | Manufacturer | Sigma Engineered Solutions | | Material | Metal | | Model Number | b5b4dfb4-09e3-40da-b716-f01bcab2f649 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 143854WH | | Product Dimensions | 2.26"D x 5.5"W x 4.2"H | | Specification Met | Csa, Nema 3r, Ul | | Style | Compact | | UPC | 031857643850 | | Unit Count | 1 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** Sigma Engineered Solutions - **Color:** White - **Material:** Metal - **Product Dimensions:** 4.2"D x 5.5"W x 2.26"H - **Style:** Compact ## Images ![SIGMA ENGINEERED SOLUTIONS 143854 Round Metal Electrical Outlet Box, Weatherproof, Easy Mount, White, (5) 1/2-Inch Holes - Image 1](https://m.media-amazon.com/images/I/61yLHRT151L.jpg) ![SIGMA ENGINEERED SOLUTIONS 143854 Round Metal Electrical Outlet Box, Weatherproof, Easy Mount, White, (5) 1/2-Inch Holes - Image 2](https://m.media-amazon.com/images/I/71cZ1EshuJL.jpg) ![SIGMA ENGINEERED SOLUTIONS 143854 Round Metal Electrical Outlet Box, Weatherproof, Easy Mount, White, (5) 1/2-Inch Holes - Image 3](https://m.media-amazon.com/images/I/71fiksjteHL.jpg) ![SIGMA ENGINEERED SOLUTIONS 143854 Round Metal Electrical Outlet Box, Weatherproof, Easy Mount, White, (5) 1/2-Inch Holes - Image 4](https://m.media-amazon.com/images/I/61NsO6teZcL.jpg) ![SIGMA ENGINEERED SOLUTIONS 143854 Round Metal Electrical Outlet Box, Weatherproof, Easy Mount, White, (5) 1/2-Inch Holes - 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. Basically they assume you will use at least one. **Q: How can it be 4.2 inches by 5.5 inches? That's not a circle.
