Since the product body is inclined, it takes into account the water slope from inside the sleeve to the indoor side! The ease of installation for fixed support and waterproofing treatment has improved!
The "Non-combustible Inclined Sleeve" is an external through sleeve made of high corrosion-resistant galvanized steel plate. It has a square flange, making it easy to install and waterproof, and the inclination of the main body prevents water from entering the indoor side from inside the sleeve. Additionally, it can be used in areas where non-combustibility is required, an important performance requirement for buildings, preventing the spread of fire into the wall structure. We also offer the "Fuji Air Duct M," which is a "fire department approved product" that can be used without issues even in narrow attics. 【Features】 ■ Can be used in areas where non-combustibility is required ■ Prevents the spread of fire into the wall structure ■ Made of high corrosion-resistant galvanized steel plate ■ Excellent corrosion resistance ■ Accurate and easy waterproofing during installation *For more details, please refer to the PDF materials or feel free to contact us.
