* Steel EMT Compression Couplings are used to connect the ends of two  EMT thinwall conduits together to extend the raceway. 
* Our steel compression couplings provide concrete tight connections when taped, and are rated for electrical applications above 600 volts.
*  Their heavy gauge steel construction maintains mechanical protection and solid grounding of one conduit to another.  
* They are also zinc electroplated for excellent corrosion protection in damp locations.
