Lifting subs are used to lift drill pipe, collar, heavy weight, and many other tools made up in your drilling assembly. They are designed with a slip for rig elevators to attach, remaining unrestrained for quick and easy connect/disconnect, while tripping in and out of the hole. ChrisCo keeps a generous supply of lifting subs in inventory. We can make these subs with any configuration you need to meet lease/operator requirements. Single pin looking down or pin down box up for fishing purposes. Custom orders always welcomed.
