Set Screw EMT to duplex push-in cable type transition fitting, ideal for commercial and institutional facilities. The 4156-DC is used to securely join 1/2" EMT to two 14/2 to 10/3 (.43" to .61" Diameter) AC/MC/MCI-A/HCF/HCFMCI-A or 3/8" flexible metal conduit. These fittings provide a huge labor savings, compared to the traditional junction box or fitting assembly installation. When using AC/MC/FMC cable simply remove the armor and expose the conductors to the desired length needed to reach the device box or enclosure. The inspection holes will provide a visual end stop for the cable or flex conduit. The use of anti short bushings is recommended. Tighten the steel screws for the 1/2" EMT conduit. Patented.
