In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

This Southwire square electrical box is built from steel for new work installations, giving you a solid, code-conscious base for switches, outlets, or fixture connections. The square shape and steel construction stand up to the wear of rough-in work better than plastic boxes, and the New Work design means it's meant to be installed before walls are finished, not retrofitted into existing drywall.

  • Material: Steel
  • Shape: Square
  • Work Style: New Work
  • Height: 4 inches
  • Weight: 1.66 lbs

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
