1" Expansion Coupling Rigid Conduit Coupling

The 1" Expansion Coupling by Southwire is designed for use in electrical distribution and lighting solutions to accommodate thermal expansion and contraction in rigid conduit systems. This coupling allows up to 4 inches of linear movement, making it suitable for outdoor structures prone to movement such as bridges, railroads, and buildings. Its weatherproof and hot dip galvanized finish ensures durability against severe environmental factors, while its internal grounding design eliminates the need for external bonding jumpers and cables.
