This extension is tailored to tall kitchens, helping to bridge gaps between a higher ceiling and the existing dishwasher-safe chimney. It creates a clean, integrated look when installed on 9–10 ft ceilings with a 15.5″ chimney, allowing the total height to reach up to 47 inches. It is designed specifically for SNDOAS hood models GD2475B/BB/GC and GD1760BPA family, ensuring precise compatibility. The unit comes pre-assembled to simplify installation and includes all necessary hardware for a quick setup. A balanced stainless steel finish supports durable, long-term use while maintaining a sleek aesthetic in modern kitchens. Ideal for upgrading visibility and airflow efficiency in tall spaces, especially where the original chimney appears short or uneven.

The 8 1/4″ wide, 63″ tall chimney extension is designed to expand the capture range and exhaust path for wall-mounted setups up to 11 feet high. It’s adjustable between 31.5″ and 63″ in height, making it suitable for various ceiling heights and hood distances from the stove. Its universal design aims to be compatible with many wall-mounted range hoods, though a quick compatibility check is recommended before purchase. The extension improves aesthetics by concealing piping and creating a tidy look, while maintaining effective airflow to contain cooking fumes near the hood’s intake.
MTAEI 31.5″ Range Hood Chimney Extension (GD17/GD24) – Assembly Required
This product provides a modular approach with adjustable height, designed to extend the upper chimney for SNDOAS GD17 and GD24 series hoods. It replaces only the upper portion of the chimney and is intended to connect with the existing lower chimney. This design keeps installation straightforward, as the unit is assembled from stainless steel panels rather than requiring new brackets or complicated hardware. It is suitable for 9–10 ft ceilings and helps to finalize a high-end, integrated appearance by concealing the exhaust routing above the hood. Pros include a compact upper section and a clean finish, though assembly is required before mounting.
HTH HTHomeprod Extension Wall Mount
HTH HTHomeprod offers a dual-piece duct cover set designed to extend wall-mounted range hoods up to 9 feet high. The two telescoping sections adjust from 23.6″ to 44″ for flexible ceiling fits. Each piece measures 11.8″ wide by 11.22″ deep, providing a substantial, clean cover over the ductwork. This option emphasizes ease of installation and visual integration with stainless steel or black hoods. It is particularly useful when upgrading a kitchen with tall ceilings where the hood is mounted away from the stove, delivering a neat silhouette and improved airflow management.

This exclusive compatibility chimney extension is designed for SNDOAS wall-mounted hood models GD1760BPA, GD1775BPA, GD1790BPA, and GD2475BPB. It pairs with the hood’s lower chimney to achieve a combined height up to 47 inches on 9–10 ft ceilings. The unit is an upper-piece replacement, aligning with the hood’s existing mounting bracket for a simple, bracket-free installation. The black finish adds a stylish contrast or match to contemporary kitchens, ensuring a cohesive and unobtrusive look while extending the duct cover up to the ceiling line.

Designed for Winflo island mount range hoods, this extension set includes both upper and lower pieces for a complete chimney upgrade. It supports ceilings ranging from 9 to 11 feet and comes with mounting hardware for straightforward installation. The retractable, adjustable design ensures a snug fit around the hood, reducing visible ductwork and improving the kitchen’s overall visual appeal. This option is particularly suitable for island configurations where the hood sits prominently above the cooktop and requires a long, clean vertical cover.
Buying Guide: Key Purchase Considerations
When selecting a chimney extension, consider the following factors to ensure a secure fit, optimal performance, and a cohesive look:
- Compatibility: Verify the hood model and brand. Extensions are often model-specific (for SNDOAS, Winflo, etc.) and may not fit other brands. Double-check the chimney diameter and height ranges before purchasing.
- Ceiling Height Range: Extensions are designed for ceilings that are 8 to 11 feet tall in many cases. Choose an adjustable extension if you have an irregular ceiling or plan to relocate the hood later.
- Material And Finish: Stainless steel and black finishes offer durability and a premium look. Ensure the finish matches your hood and cabinet hardware for a seamless appearance.
- Installation Type: Some extensions come pre-assembled; others require assembly. Consider your comfort with tools and brackets, plus whether the lower chimney will still connect securely.
- Aesthetics And Concealment: The purpose is to hide exposed ductwork and create a built-in feel. A well-finished chimney extension should align with ceiling lines and hood dimensions.
- Length And Adjustability: Look for adjustable heights (e.g., 31.5″ to 63″ or 23.6″ to 44″ ranges) to accommodate future kitchen layout changes or different ceiling heights.
- Accessibility For Maintenance: Ensure the extension allows access for cleaning and any potential repairs to the hood or ducting.
- Warranty And Returns: Check return windows and manufacturer warranties in case of compatibility issues or fit concerns.
- Cost And Value: While not listing prices, weigh the installation effort against the aesthetic and airflow improvements, especially in high-ceiling kitchens.
Usage Tips
- Measure Ceiling And Hood: Before buying, measure the current lower chimney height and ceiling distance to the hood to confirm the extension length you need.
- Check Connection Points: Confirm that the upper chimney extension will connect to the existing lower portion without requiring extra brackets.
- Professional Installation: For complex installs or ceiling work, consider professional installation to ensure a secure and compliant setup.
