Abstract
A method and apparatus for reinforcing duct work is provided. In one embodiment, a reinforcement comprises a conduit having a first end and a second end. A pair of plugs is insertable into the first and second ends of the conduit. Each of the plugs has a groove extending along the circumference of the plug, and the plugs are crimped inside the conduit along the grooves. Each of the plugs may have a threaded end extending out of the plug and being retractable into said plug. Alternatively, each of the plugs may have an internally threaded opening extending at least partially through the plug. In this embodiment, the conduit can be secured to duct work by aligning the conduit with holes in the duct work, and inserting a bolt through the holes and into the internally threaded openings of the plugs.
