Threaded Couplings The threaded couplings, including electrical conduit couplings, are manufactured from tubular steel.

The electrical conduit couplings are used for connecting together lengths of electrical conduit or to connect electrical fittings to the conduit.

In the alternative to the Tribunal granting NCI’s request to exclude threaded couplings from the finding, Emco/ERI requested that the Tribunal exclude electrical conduit couplings.

Emco/ERI requested that the Tribunal exclude electrical conduit couplings retroactively to the date of the original finding, July 16, 2003, or the date of the last known Canadian production of electrical conduit couplings, whichever was more recent.
