Abstract: A rod hanger uses a spring insert clip horizontally insertable into a sheet metal housing to embrace and grip the threads of a vertical rod. The hanger has a sheet metal housing with parallel slots in opposite walls parallel to the rod. The clip has spring thread-form legs which are guided into the slots and held embracing the rod. The clip is U-shape with parallel legs which project from and snap behind one of the walls of the housing. The hanger may be in the form of a beam clamp or flange clip.
