Modular Chimney Caps 3/4
Extend your stainless steel chimney cap with 3/4 modular extensions from Chicagoland Fireplace & Chimney Restoration. Designed for precision fit, increased draft height, and long-term structural durability.

Multi-flue chimney caps made from 304 stainless steel are designed to provide heavy-duty protection while accommodating chimneys with multiple flues in one stack. This 3/4 mesh model with a reversible mounting skirt adds even more flexibility, making it an excellent choice for both new construction and retrofits. Its ability to flip the base offers a clean solution to installation challenges—especially when working with uneven or non-centered flues.
Crafted from corrosion-resistant stainless steel, this chimney cap is built for longevity. It maintains its form and function even under constant exposure to moisture, wind, and freeze-thaw cycles, making it a favorite among professionals working in four-season climates.
The reversible mounting skirt allows the cap to be installed in two different ways: either “right side up” or flipped, depending on the layout and dimensions of the chimney crown. This makes it easier to align with flue liners or secure to brick surfaces without extensive modification.
Whether your chimney has two, three, or more flues exiting the crown, this cap adapts to your setup while maintaining structural integrity and performance.
Designed for long-term exposure to the outdoors, 304 stainless steel holds up under the most demanding conditions. It resists rust and corrosion, even in coastal or high-humidity environments, and retains its appearance over time without paint or coatings.
This cap is also designed to minimize the risk of spark escape, making it a fire-safe addition to your chimney system.
Despite its rugged build, the 304 stainless steel multi-flue cap provides a refined appearance. Its clean lines and uniform welds offer a professional finish that complements both brick and stone chimneys. The silver tone of the stainless steel blends seamlessly with modern and traditional home exteriors.
Whether you're protecting a historic chimney or adding the final detail to a new build, this cap delivers the reliable coverage and clean look your project demands.
