Eaton COUP Locking Coupling for Conduit Fixture Stems

Crouse-Hinds COUP locking couplings are used in both hazardous and non-hazardous areas to lock a light fixture conduit stem into a conduit hub to prevent the conduit stem from loosening when the fixture is relamped and torque is transferred to the fixture stem.  COUP couplings prevent loosening of the fixture stem due to vibration.
