RACO 2156 Set-Screw Conduit Coupling

This steel coupling joins two 4-inch trade-size EMT, IMC or RMC conduits in a straight line. The set-screw connection secures each pipe without threading tools. UL listed and concrete-tight, it suits commercial and industrial raceway installations. The plain gray finish matches standard conduit appearance.

4-Inch Trade Size and Set-Screw Connection

The coupling accepts conduit with a 4-inch trade size and uses set screws to lock each length in place. Overall length is 4 23/32 inches with an overall height and width of 4 25/32 inches. This single dimension determines whether the fitting matches the raceway being installed.

Steel Body Sustains Mechanical Load

The steel body resists deformation when conduit runs are pulled tight or subjected to vibration. At 2.57 lb the fitting adds mass that helps dampen movement in long straight sections. Concrete-tight rating means the joint maintains integrity when embedded in poured slabs.
