Q&As

1 - 2 of 2 Questions

Q: What is the exact measurement of the inside diameter of the 7 inch side?

1 Answer
  • A: The DuraVent DuraBlack Increaser is 7 inches. DuraBlack pipe uses nominal sizing, meaning the specified diameter (7 inches in this case) refers to the actual interior diameter of the pipe, allowing it to connect properly to other components of the same nominal size.

Customer Service goes above and beyond every time.

Ordered at Tractor Supply in Hillsborough NH at Customer Service Counter as the item is available on line. Product is carried by Tractor Supply, just not at this location. Service personnel were knowledgeable regarding my product needs and agreed this item might resolve my dilemma how to connect parts of my Tractor Supply Coal Stove to my flue. Can not say enough about the staff and the helpful manner for me as a customer. When staff are not sure, they are comfortable saying so and then proceed to locate a staff member who may have more experience with my questions. Always a positive experience for me as a customer at Tractor Supply.

Yes, I recommend this product.
