The Imperial 6 Galvanized Take-Off is a type of starting collar made from 30-gauge galvanized steel, designed to provide a transition point from a rectangular trunk duct supply line to a round branch duct in an HVAC system. The fishlock tabs help ensure the connection between the take-off and the main rectangular duct remains securely connected, preventing movement or disconnection. Secure with self-tapping galvanized screws. Moreover, the galvanized steel construction of this take-off adds durability and corrosion resistance, making it suitable in HVAC systems where the ducts consistently encounter air moisture and other potentially corrosive elements.
