Details products: 

Semi-Bridge Coupling   
- Small non-threaded bridge in the center
- Smaller diameter steel end portions fit together in the center bridge area of the coupling
- Steel cannot thread past bridge area
- Semi-bridged couplings are most suited to high torque machines
- Most Rope and HM Threaded couplings are semi-bridged
 

                                                            
Full-Bridge Coupling 

- Eliminates the potential for the coupling to creep along the threaded joints
- Typically used in surface applications
- Better uncoupling characteristics and tend to maintain tighter joints
- Less chance of jamming
- Best suited to machines equipped with independent rotation (i.e., S36IR rock drill)
       

                          
Adapter Coupling    

 
- Used when changing from one thread type, or size, to another and are typically required only in special circumstances.
