3-1/2" Expansion Coupling

3-1/2" Expansion Coupling Rigid Expansion Coupling The 3-1/2" Expansion Coupling by Southwire is designed to accommodate up to 4 inches of linear movement caused by thermal expansion and contraction, making it suitable for use in electrical distribution and lighting solutions. This rigid expansion coupling is ideal for joining two sections of rigid UL 6 conduit subjected to longitudinal movement. Its weatherproof construction supports applications on outdoor structures prone to movement such as bridges, railroads, and buildings. The internal grounding design eliminates the need for external bonding jumpers and cables, ensuring reliable circuit integrity.
