Threeproof Fabric Duct — waterproof, heat resistant, and abrasion resistant. Built to reduce maintenance and extend service life while staying lightweight and easy to install. Key benefits Longlasting performance: Waterproof and abrasion resistant construction lowers and replacement frequency, saving time and cost. temperature tolerance: Safe operation from 22°F to 212°F (30°C to 100°C), so it won't crack in winter or warp under heat. Flexible and adaptable: 360° bend capability lets the duct route around corners and obstacles without kinking; it also compresses and extends for compact storage. Easy to install and : Cut to the required length, secure with the included clamps, and reinstall quickly. Lightweight design reduces labor and handling effort. Function and compatibility Designed for HVAC systems, dryer vents, and workshop exhaust applications. Suitable for commercial and industrial spaces such as warehouses, gyms, and cleanrooms. Works with typical vent and duct connections; clamps are provided for a tight fit. (Wear gloves during installation to avoid injury.) Practical features Temperature range: 22°F to 212°F (30°C to 100°C) — reliable across extreme cold and heat. Threeproof fabric minimizes moisture damage and surface wear in demanding environments. Fully flexible construction enables easy routing through complex layouts and around equipment. Use scenarios HVAC retrofit in a warehouse: Route air supply or ducts around shelving and equipment without cutting rigid ducting or risking kinks. Home or commercial dryer vent: brittle or damaged ducting with a heatresistant, waterproof hose that resists abrasion from handling and airflow. Workshop exhaust or gym ventilation: Withstand fluctuating temperatures and frequent movement while providing a durable, lowmaintenance ducting solution. Installation tips Measure and cut to the needed length; secure both ends with the supplied clamps. Wear gloves when cutting and fitting the duct to prevent injury. Compressible design simplifies storage when not in use. This duct combines durability, heat performance, and flexible routing to meet common HVAC and venting needs while reducing maintenance and installation effort.
