Exposed Spiral Ductwork

The duct 2-foot rule generally refers to the requirement that duct connections to equipment must be made within 2 feet of the appliance or fitting to minimize leakage and pressure loss. It is a best-practice guideline used in HVAC and industrial ventilation design to ensure efficient airflow and compliance with installation standards such as SMACNA.

Exposed spiral ductwork is used in industrial ventilation, dust collection, and material handling systems. It efficiently moves air, fumes, dust, and particulates through facilities such as manufacturing plants, warehouses, woodworking shops, and metal fabrication facilities where ductwork is left visible rather than concealed within walls or ceilings.

Spiral ductwork is commonly available in galvanized steel, stainless steel, and aluminum. The appropriate material depends on the application — galvanized is standard for general ventilation, stainless steel suits corrosive or high-moisture environments, and aluminum is used where lightweight construction and corrosion resistance are both priorities.

LaserLock uses a clamp-together assembly method that eliminates the need for welding or specialized tools. Components including pipes, elbows, adapters, and branches snap and clamp into position, allowing technicians to configure runs quickly. Design assistance and installation tips are available from Duct Incorporated to support proper setup.
