Renown’s Knuckle Joint is designed to provide additional flexibility in the tool string. This additional flexibility is often required when the Bottom Hole Assembly is run through a restriction or high deviation within the wellbore. It can be used in certain fishing applications to help centralize or de-centralize the fishing tool. The joint provides a 7.5 degree deflection and internal pressure sealing throughout the full deflection of the tool with a large through-bore allowing the use of ball activated tools below the Knuckle Joint. Knuckle Joints can also be run in tandem if required.
