There are several selctions for the knockout size and location that made running the conduit a snap. The build quality and color are on point. They are easy to install with the tabs included and a good value for the money. I couldn't find this color/configuration at my local big box or Ace Hardware.

Made from good materials, and reasonably heavy duty. This outdoor single-gang box is painted white. The paint is tough and survives some handling. After installation, it does seem weather proof, but only time will tell. Had to add silicone sealant to each of the plugs to ensure weatherproofing. Will buy again. ## Frequently Bought Together - SIGMA ENGINEERED SOLUTIONS 14250WH Metal Electrical Outlet Box, Weatherproof, Easy Mount Plug and Receptacle Protector, White, (3) 1/2-Inch Holes, 1 Gang Box - TayMac MM410C Single Horizontal/Vertical Mount 1-Gang Weatherproof In-Use Electrical Outlet Cover for Home Improvement, 2.75 in, Clear - TAYMAC ML500W Single-Gang Mount 16-in-1 Flat Nonmetallic Weatherproof Vertical/Horizontal, 1-Pack, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/46783314-sigma-engineered-solutions-14250wh-weatherproof-1-2-3-hole-1](https://www.desertcart.pt/products/46783314-sigma-engineered-solutions-14250wh-weatherproof-1-2-3-hole-1) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-11*
