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 a 500-foot spool of Southwire 6 AWG THHN building wire, stranded copper with a black PVC insulation and nylon jacket. It's rated for 600 volts and 90°C, with a 60 amp rating, making it a solid choice for feeder circuits, subpanels, and other branch circuit runs that call for heavier gauge wire. UL listed and rated for wet locations, it holds up in damp conduit runs as well as dry indoor installs.

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.
