Abstract
A duct reinforcing rod and fabrication apparatus for use with a conduit and a threaded element dimensioned to fit within the conduit includes a positioning device to position the conduit at an insertion position and an insertion device for inserting the threaded element a predetermined distance into the conduit. A deformation device is also employed to deform the conduit such that the deformation occurs at two locations on the conduit, the two locations being longitudinally spaced from one another along a length of the conduit.
