ABSTRACT:
A support assembly for supporting a flexible duct includes a radius strap for maintaining the desired angle of bend for the flexible duct. The radius strap retains its shape through ribs along the back side of the strap. The assembly is secured at both ends to the flexible duct via arms branching off of cross pieces which branch off from the radius strap. The arms contain slots which allow varying connection devices to pass through and secure the flexible duct to the assembly itself and to varying pieces of HVAC equipment.
