CLLOMAGY 9 x 9 in Chimney Cap — Galvanized Steel Square Chimney Cover, Mesh Screen for Animals & Rain

CLLOMAGY’s 9" x 9" galvanized chimney cap is a square outdoor chimney cover designed to keep out animals, debris and weather while improving draft and venting for square flues.

This chimney cover is built from heavy-gauge galvanized steel to resist rust and hold up to outdoor conditions. It fits a wide range of square flue tiles and metal chimneys, installs without special tools, and combines a hooded top with a mesh screen to block birds, leaves, rain and light downdrafts. The design focuses on durability, straightforward fitment, and maintaining reliable ventilation for wood stoves, fireplaces, boilers and masonry chimneys.

How does this chimney cap protect my chimney from animals and debris?

The CLLOMAGY cap uses a stainless-feel galvanized mesh around a solid hood to prevent small animals and loose debris from entering the flue. That barrier keeps nests, leaves and other blockages out while still allowing smoke and gases to escape.

• Galvanized mesh screen blocks birds, squirrels and leaves.
• Raised hood sheds rain and snow away from the flue opening.
• Close-fit design reduces entry points for pests and drifting debris.

Will this cap withstand harsh weather and high heat?

Yes—the cap combines a 14-gauge steel base with a 24-gauge galvanized hood for a balance of strength and corrosion resistance. It’s engineered to resist deformation in wind, rain and snow while tolerating the heat typical of residential wood-burning appliances.

• 14-gauge galvanized steel base provides structural durability.
• 24-gauge galvanized hood resists rust and warping.
• Built for outdoor exposure to snow, rain and wind without losing shape.

What chimney sizes and types does the 9" x 9" cap fit?

This square cap is sized to cover flue tile openings that range from about 7.5" to 9.5" per side, making it a flexible option for many masonry and metal chimneys. It works with clay, terra cotta, brick, masonry flue tiles and compatible metal pipes used on outdoor fireplaces and wood stoves.

• Fits square flue tiles 7 1/2" to 9 1/2" per side.
• Compatible with masonry, clay, terra cotta and some metal flue tops.
• Designed for common residential wood stove and fireplace installations.

How simple is the installation process?

Installation is straightforward and requires no special drilling or complex tools. The cap slides over the flue tile, aligns with the pre-drilled mounting holes, and secures by tightening screws against the outside flue wall for a snug fit.

• Slide-in fit for the chimney flue liner—no cutting needed.
• Side-mount screws tighten into pre-drilled holes for secure attachment.
• Can be fitted during a routine chimney inspection or basic DIY session.

Who this is for: The CLLOMAGY 9" x 9" chimney cover suits homeowners and property caretakers with square flue openings who want a durable, maintenance-reducing solution. It’s ideal for owners of wood-burning stoves, fireplaces, boilers and outdoor masonry chimneys seeking improved ventilation, fewer blockages from animals and debris, and a corrosion-resistant cap that can endure seasonal weather. If you need a simple-to-install, heavy-gauge steel chimney protection for a 7.5"–9.5" square flue, this cap is a practical choice.
