Slip-in chimney cap – Slides snugly into the flue tile without bolts, making installation straightforward.
Adjustable bolt-on chimney cap – A flexible version designed to fit both square and rectangular flues.
Multi-fit chimney cap – A universal option that adapts to homes with varying flue sizes.
Multi-flue chimney cap – Installed with masonry screws into the chimney crown, this style covers multiple flues with a single cap.
Sealing damper chimney cap – Provides an airtight seal that reduces energy loss while keeping out moisture and debris.
Universal chimney cap – Works across most round and rectangular flues with flanges that create a tight, secure fit.
