XJG Expansion Coupling, 4" Diameter, 4" Movement, Steel

XJG expansion couplings are used with rigid metal conduit and IMC to couple together two sections of conduit subject to longitudinal movement, in conduit runs to prevent damage to conduit supports such as in a building or on a bridge, indoors or outdoors in long conduit runs to permit linear movement caused by thermal expansion and contraction, in conduit runs that cross structural joints, on long conduit runs to prevent conduit from buckling and ensuing circuit failures.
