Buying Guide

Material and corrosion resistance

Choose galvanized steel for cost-effective rust protection or stainless steel for longer life in coastal or high-moisture areas

Fit and flue configuration

Match cap dimensions to your flue opening and single- versus multi-flue layout to ensure a secure, weather-tight fit

Mounting style

Bolt-on caps provide a more permanent attachment for masonry chimneys; verify bolt pattern and clearance for your chimney crown

Spark arrestor and mesh size

Look for a mesh that balances ember containment with adequate draft—finer mesh blocks more sparks but can restrict airflow

Maintenance and serviceability

Prefer designs that allow easy removal for inspection and cleaning, and choose materials that simplify long-term maintenance
