Kelly Saver Subs
Kelly Saver Subs are used to extend the life of the Kelly by taking the connection wear each time it is made up to a drill stem component. The saver sub connection is sacrificed because it can be easily repaired or inexpensively replaced. 

We have Kelly Saver Subs available in:
2 7/8" SLH90 and 3 1/2 IF.

Please contact Rig Service for more information and availability.
