Buying Guide: What To Consider When Choosing A Chimney Flue Hole Cover
- Size range: Look for adjustable covers that span 4″ to 8″ or more to cover most common chimney openings without gaps.
- Material and finish: Steel cores with powder-coated or matte black finishes offer durability and corrosion resistance in high-heat environments.
