ABSTRACT:
An outside corner fitting including an arcuate channel having a radius of curvature greater than a predetermined minimum bend radius for the cable to be installed in the duct system. A first embodiment of the invention fits within straight ducts and allows the straight ducts to be placed flush with the outside corner of the wall. A second embodiment features an outside corner fitting that abuts against the straight ducts and is mounted directly to the wall. Both embodiments include a cover having a first edge and a second edge, the first edge being shorter than the second edge. The shorter first edge minimizes the gap between the cover and the wall if the wall is not exactly 90 degrees.
