The Bridgeport 280SPMB 1/2" To 3/8" Mighty-Merge® Combination EMT Transition Coupling with PUSH-EMT and Snap-In connects EMT to 3/8" flexible metal conduit or 14/2 to 10/3 AC/MC cable. Snap-in Transition Couplings have a quick install snap-in end for AC/MC cables and flexible metal conduit and a labor saving push-in end for EMT. This coupling is ideal for transitioning fixture whips above the drop ceiling and for continuing a run of MC down the wall to emergency lights. Made of zinc, the body provides corrosion resistance for long-term use in most environments. The transition coupling meets all the mechanical and electrical requirements of the National Electric Code.
