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 500-foot spool of Southwire 12 AWG THHN is stranded copper wire built for general circuit wiring, conduit runs, and panel feeds where you need a dependable 20-amp conductor on hand. The PVC insulation with a nylon jacket resists heat, flame, and sunlight, and it's rated for wet locations, so it works equally well fished through indoor conduit or run outdoors. At 600 volts and a 194°F temperature rating, it covers most standard residential and light commercial jobs, and being UL Listed means it meets code requirements electricians rely on.

  • PVC insulation, nylon jacket - flame retardant and UV resistant

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.
