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 is Southwire's 10/3 Romex NM-B, the go-to cable for circuits that need more headroom than standard 12 or 14 gauge wire can handle, like electric ranges, dryers, or dedicated 30-amp shop equipment. It's a 200-foot coil with three solid copper conductors plus a copper ground, jacketed for indoor use and rated for the job from panel to appliance.

  • 10/3 gauge, 3 conductors plus ground, solid copper
  • 30 amp rating, 600 volt, 90°C temperature rating
  • PVC insulation with a nylon jacket, flame retardant
  • UL listed, rated for direct burial, made in the USA

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.
