XJGD Combination Expansion/Deflection Couplings

Crouse-Hinds series XJGD combination expansion/deflection couplings are used with rigid metal conduit and IMC to couple together two sections of conduit subject to movement due to thermal expansion and contraction.  They are installed indoors or outdoors in long conduit runs to permit linear and axial movement and to accommodate angular and parallel misalignment.  

XJGDs maintain electrical continuity without the need for an external bonding jumper and clamps.
