US Duct Clamp Together T Branch 10-10-10, 10" Diameter, Galvanized, 18 Gauge, Us Duct, Mfr#: RBT1090.G18

T-branches have one "leg" coming off of the main line at 90 degrees forming a ‘t’. T- branches are constructed of 18 gauge steel which allows us to solid weld the branching parts to the trunk to ensure a very tight seal.
