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

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.

About Product Overview

The Klein Tools AFCI/GFCI Electrical Outlet Tester is a compact, professional-grade tool built to validate outlet wiring and protective functionality quickly and reliably. Designed for electricians, contractors, landlords, and serious DIYers, it helps you confirm that outlets are wired correctly and protected by both AFCI and GFCI systems.

Key benefits that matter in real-world use:

  • AFCI and GFCI verification in one tester: instantly confirms the presence and operation of arc-fault and ground-fault protection, reducing the guesswork on safety-critical outlets.
  • Automatic Ranging: adapts to different outlet configurations automatically, delivering clear results without manual adjustments.
  • Audible alert: built-in sound provides immediate feedback, even when you’re working with tools or PPE on.
  • Automatic Delay Shutoff: conserves battery life by powering down after tests, so you’re ready for the next outlet without worrying about drain.
  • Ready to use out of the box: ships with a AAA battery included, so you can test immediately without hunting for a replacement.
  • Durable, high-visibility design: the black/orange housing makes the tester easy to spot in a bag or on a crowded job site.
  • Safety-certified build: UL Listed and ETL Listed, giving you confidence in performance and compliance on the job.
  • Two-year warranty: backed by Klein Tools for long-term reliability and peace of mind.

Ideal applications include home renovations, property inspections, rental maintenance, and any scenario where you need fast, dependable confirmation that outlets are correctly wired and protected. The tester’s simple, at-a-glance indicators and audible cues make it a practical companion whether you’re diagnosing a miswired outlet or validating post-work safety after wiring upgrades.

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 co-op 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.
