Angle Boot, End Boot, Streight Universal Boot
HVAC boots are made of galvanized sheet metal and are designed to convert ductwork into a vent to heat a room. In a home, the trunk of the HVAC system either runs through the ceiling or the basement of the home. The trunk consists of the main ductwork line that supplies all the air throughout the house. From the trunk, there are lines that branch out the run to each room in the home.
