You might try their FLBR5420 series (for wood floors). These require a 5" hole in the floor and the top trim plate is 6 5/8" in diameter. It is a surface mount version. **Q: Will this ever be offered in an oil rubbed brass finish?** A: You can find other options here on Amazon. Try searching Lew Electric 812-DFB. The below link might also work. https://www.amazon.com/stores/LewElectric/FlushMetalFloorBoxes-812Series_FloorBoxes/page/31737FC6-7297-4335-B19C-A5A4AD6585CF **Q: Do they make one for a single socket ?** A: I don't know. But this two-socket one comes with nickel-plated caps that screw in to any unused socket. They are then flush and look nice. **Q: Where can I get replacements for the rheaded plugs in nickel?** A: We don't sell replacement plugs for this item. You may have to check with the manufacturer directly to see if they have the plugs or not. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect. *by S***N on February 12, 2026* Looks great! Love that it’s flush with the floor and was easy to install. ### ⭐⭐⭐⭐⭐ Sturdy and very nice design *by A***G on March 1, 2026* Easy to install, very sturdy. Photo is without plate as I wanted to test these. ### ⭐⭐⭐⭐ Could do with better instructions. *by J***T on December 22, 2025* Does what it’s meant to do, but instructions could be better. It’d be nice to see what depth it’s meant to be set at as opposed to guessing and shimming. ## Frequently Bought Together - Arlington Flush Floor Box Kit (Brass) - ENERLITES Screw Cap Cover Floor Box kit, 5” x 2.8” 1-Gang, 20A Tamper-Weather Resistant Duplex Receptacle Outlet, Watertight Gasket, Corrosive Resistant, UL Listed, 975506-C, Brass --- ## 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.co.uk/products/347294295-flush-floor-box-kit-brass](https://www.desertcart.co.uk/products/347294295-flush-floor-box-kit-brass) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
