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

Upgrade your laundry vent with the Deflect-O Supurr-Flex 20 ft L X 4 in D Silver Aluminum Dryer Transition Duct. This two-piece, flexible aluminum duct is purpose-built for longer vent runs, delivering steady airflow from your dryer to the outdoors while staying durable and simple to install.

Why this two-piece Supurr-Flex setup stands out

  • 20 feet in length, two pieces — a longer run with fewer joints makes routing easier through tight spaces and around obstacles, reducing potential leak points.
  • 4-inch diameter — a standard size that fits most residential clothes dryer exhaust outlets for compatibility and straightforward installation.
  • Silver aluminum construction — lightweight yet resilient, resistant to heat and crushing, and designed to maintain airflow over time.
  • Flexibility with reliability — Supurr-Flex design offers bendable routing while preserving interior path for smooth air flow, helping to minimize lint buildup and improve dryer efficiency.

Ideal uses and who benefits most

  • For new installations or remodeling projects where a longer vent path is needed in laundry rooms, basements, or utility closets.
  • When upgrading from vinyl or foil ducts to a durable, metal solution that’s better suited for continued, safe venting.
  • Homes seeking easier maintenance and fewer joints along a dryer vent run, contributing to more consistent drying times.

Practical tips for best results

  • Route the duct with gentle bends and avoid sharp angles to maintain optimal airflow.
  • Secure the duct with appropriate metal clamps and mountings to prevent sagging and leaks.
  • Keep the exterior vent hood clear of snow, debris, and lint buildup to sustain efficient exhaust.
  • Periodically inspect the duct for kinks or crushed sections and replace as needed to preserve airflow.

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.
