Lew Electric Round Floor Box Kit (Screw Plugs, Brass) - Clean Floor

In this review of the Lew Electric Round Floor Box Kit the bottom line is simple: this kit is for homeowners and contractors who need a discreet, solid-feeling power solution for finished floors. The single biggest reason to buy is the combination of a metal cover with an included duplex outlet that installs quickly into a subfloor and sits nearly flush, delivering reliable in-room power without a bulky profile. Installation is straightforward and the kit is ETL listed for North America, which gives confidence for indoor projects.

Key Features

• Round metal cover: The solid brass-look round cover provides a low-profile, finished appearance that blends with many floor materials.
• Included duplex outlet: The kit ships with a single duplex 15A receptacle, so the box is ready for power immediately on installation.
• Certifications: ETL listed for USA and cETL listed for Canada with listing number 4004534, ensuring it meets applicable safety standards.
• Secure mounting: Three wing clamps secure the box to the subfloor so the unit stays stable and aligned during and after install.
• Compact dimensions: The cover is 5 1/16' round with a 3 7/8' cutout and 3 1/4' depth, making it suitable for common subfloor depths.

Who It's For

The Lew Electric Round Floor Box Kit is best for interior residential projects where a discreet floor outlet is preferred, such as living rooms, home offices, and conference rooms. Installers who value a metal cover with a simple screw-plug finish will appreciate the kit for retrofit or new construction subfloor work.

It is less appropriate for outdoor, wet locations or installations that require more than a single duplex receptacle or specialized wiring configurations. Buyers needing multiple outlet types or heavy-duty commercial boxes should consider alternative products.
