A straight oval supply boot is a fundamental component in heating, ventilation, and air conditioning (HVAC) systems. It is designed to connect the main supply duct to an air distribution register or diffuser, specifically for systems utilizing oval-shaped ductwork. This boot is typically constructed from sturdy materials like galvanized steel or aluminum to ensure durability and structural integrity.

The straight oval supply boot is engineered with precision to facilitate a smooth transition of airflow from the main duct to the supply register. It often features a flanged opening that securely attaches to the duct, while the other end is designed to accommodate the register or diffuser.

This component plays a crucial role in maintaining an efficient and balanced airflow within a building's HVAC system. It helps regulate and direct conditioned air to various spaces, contributing to overall comfort and climate control.

Due to its robust construction, a straight oval supply boot is resistant to wear and corrosion, ensuring long-term durability and reliability. It is available in various sizes and configurations to suit different ductwork layouts and system requirements.
