ABSTRACT:
A Non-metallic Elbow Conduit Transition Fitting is disclosed. The fitting is specifically suited to interconnect vertical electrical conduit runs and horizontal electrical conduit runs in commercial construction environments. The fitting is suitable for immersion within poured concrete floors used in commercial building construction. The fitting is designed to threadedly engage a vertical run of EMT (metallic) conduit with a horizontal run of nonmetallic (e.g. PVC) conduit. A final aspect of the fitting is that it must have a short sweep angle bend so that it is adequately buried within a concrete floor made from 6 inches of concrete.
