Buying Guide
What size do I need?
Most covers fit 4″–8″ flue holes; confirm your chimney’s opening diameter before purchasing. If your opening sits near 5″–7″, these adjustable models are ideal.
Material and durability considerations
Look for steel construction for long-term durability and corrosion resistance. Black or almond finishes offer different aesthetic matches for wall colors and room style.
Install and concealment considerations
Choose models with adjustable anchors for a secure fit on various wall types. If you want hiding capability, select decorative options that align with your interior decor, such as almond or white finishes.
Where should you install?
Install flue hole covers over wall openings that are visible or draft-prone. Ensure the chosen cover does not obstruct any venting pathways and is firmly mounted to prevent shifting.
Maintenance and longevity
Regularly inspect for rust or loosening screws. Clean with a dry cloth; avoid abrasive cleaners that could scratch the finish. A fresh coat of paint can refresh decorative covers if desired.
Compatibility and replacement notes
Many products list BM0026 and BM0353 as compatible models. If you plan to replace several parts, verify that the new cover matches the hole size and mounting method of the existing frame.
What to avoid?
Avoid covers that are too small for your opening, as gaps can allow cold air infiltration. Also avoid overly thin materials for high-traffic rooms where impact risk is higher.
