The Rectangular Access Door is designed to provide easy and safe access to airflow control dampers, fire dampers, and other ventilation and air conditioning equipment inside ducts. It facilitates inspections, maintenance, and adjustments without the need to dismantle the system.

The sandwich-type design, with a flat profile and oval contours, offers rigidity and durability, while the fasteners—galvanized steel screws and nuts—ensure corrosion resistance and a secure fit. The door is made of galvanized steel and features an airtight internal seal, ensuring reliability and airtightness in all applications.
