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 DuraVent 6 in. D Steel Damper is your go-to solution for precise airflow control in Type A vent systems. Built for durability and dependable performance, this adjustable damper lets you fine-tune draft, optimize combustion, and improve overall venting efficiency in a single, compact unit.

Why this damper stands out

  • 6-inch diameter to fit standard Type A vent openings with a snug, secure fit.
  • 24-gauge steel construction delivers long-lasting durability under high-heat conditions.
  • Adjustable design provides precise control over exhaust flow and draft, so you can adapt to changing weather, fuel types, or appliance usage.
  • Black finish offers a clean, low-profile appearance that blends with most hearths and vent runs.
  • UL Listed for safety and code compliance, giving you confidence in installation and performance.
  • Maximum temperature: 2100, ensuring reliable operation across a wide range of high-heat venting applications.
  • Type A vent compatibility ensures seamless integration with approved vent systems.
  • Boxed packaging protects the damper during shipping and handling, making on-site installation straightforward.

Ideal uses and practical benefits

Designed for installations that require dependable draft control, this 6-inch damper is ideal for residential vent runs where Type A venting is specified. Use it to:

  • Regulate chimney draft for stable flame performance and efficient fuel use
  • Reduce back-drafting during cold weather and when the appliance is not in use
  • Fine-tune exhaust flow to minimize heat loss and maintain comfortable indoor temperatures

Who benefits most

  • Homeowners upgrading or replacing aging dampers in Type A vent systems
  • HVAC and fireplace professionals seeking a reliable, UL-listed damper with a robust 24-gauge steel build
  • Renovators and new installations where precise, adjustable draft control is a priority

Installation and care tips

  • Confirm 6-inch opening compatibility with your Type A vent system before installation.
  • Position the damper for easy access and reliable operation from the exterior or an accessible interior location.
  • Use the adjustable mechanism to dial in the optimal balance between draft and exhaust, especially during seasonal changes.
  • Inspect the damper periodically for signs of corrosion or obstruction and clean as needed to maintain smooth operation.

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.
