Constructed from 26-gauge aluminum, this duct provides a strong, durable airflow passage that holds its shape under normal HVAC and exhaust system conditions. It is sold in cases of 15 sections, making it a practical choice for contractors, HVAC technicians, and plumbers who need a reliable supply of rigid duct on hand for multiple jobs or larger installations.\u003c\/p\u003e\u003cp\u003eRigid aluminum duct is a preferred material for in-wall duct runs, dryer exhaust systems, bathroom exhaust fans, range hood venting, and other ventilation applications where a smooth interior surface is required. The smooth inner wall reduces airflow resistance compared to flexible duct, which helps maintain proper exhaust velocity and system efficiency. This is especially important for dryer venting, where lint accumulation in corrugated duct can create a fire hazard. Rigid duct minimizes that risk and meets most local and national building codes for concealed in-wall use.\u003c\/p\u003e\u003cp\u003eThe 110643 rigid aluminum duct sections are easy to cut, join, and seal with standard sheet metal tools, duct tape, or mastic sealant. At 4 inches in diameter, this duct size is compatible with most residential dryer vent connections, bathroom exhaust fans, and range hood outlets. The 26-gauge aluminum construction offers a balance of rigidity and workability, allowing installers to make clean cuts and secure connections without specialized equipment. Each 5 foot section is lightweight and easy to handle, speeding up installation on the job site.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e26-gauge rigid aluminum construction for durable, code-compliant ventilation runs\u003c\/li\u003e\n\u003cli\u003e4 inches diameter by 5 foot length per section, sold 15 sections per case\u003c\/li\u003e\n\u003cli\u003eSmooth interior surface reduces airflow resistance and lint buildup for safer dryer and exhaust venting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Builders Best 110643 rigid aluminum duct provides a code-compliant, smooth-wall ventilation solution in a contractor-friendly 15-per-case quantity.
