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 Romex Type NM-B WG in 8/3 gauge, built for circuits that need more headroom than standard 14 or 12 gauge wire can give you - think electric ranges, dryers, subpanel feeds, or other 40-amp loads. Each 25-foot coil has three stranded copper conductors plus a copper ground, wrapped in PVC insulation and jacketed for indoor use.

The 90-degree temperature rating gives it flexibility across different termination requirements, and the flame-retardant, sunlight/UV-resistant jacket holds up well in the conditions it's rated for. This is indoor, non-direct-burial, non-wet-location cable, so keep it inside walls and conduit runs where it belongs. UL listing means it's been tested to the standards inspectors expect to see.

  • 8/3 AWG, 3 conductors plus ground, stranded copper
  • 40 amp rating, 600V rated, 90°C temperature rating
  • PVC insulation, nylon jacket, flame retardant
  • Indoor use only - not for direct burial or wet locations

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.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
