Overview

The NSI Industries Mighty-Merge Transition Fitting (SKU 4157-DC) is a zinc die-cast coupling designed to join 3/4" EMT conduit to 3/8" AC/MC or FMC cable. This patented fitting eliminates the need for junction boxes, reducing labor time by up to two-thirds compared to traditional installations. The formed steel body includes a rounded bushing to protect conductors during installation. The TITE-BITE® connector uses a single screw to securely grip flexible metal cable, allowing the armor gripping saddle to remain open during insertion for easier setup. The fitting accommodates cable sizes from 14/2 (.43") to 10/3 (.61") and is compatible with 3/8" flexible metal conduit and 1/2" EMT. Its zinc die-cast construction and ball-burnished finish provide durability for commercial and institutional applications. Standard packaging includes 25 units per box and 100 units per case.

Specifications

Application
Set Screw type transitional fitting ideal for commercial and institutional facilities. The 4157-DC is used to securely join EMT to two armored or metal clad cables and 3/8” flexible metal conduit. New and Improved: Now features a tapered body and a rivet to separate cables during installation. A 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 strap screws between the armor convolutions, and for the 3/4" EMT conduit. Patented.
