The LiMAR® Knuckle Joint is designed to provide a point of flexibility along the length of a wireline toolstring.

Configuring a Knuckle Joint within the toolstring enables it to pass unrestricted over nipple shoulders, tubing crossovers and other points where a rigid toolstring may encounter difficulty. The Knuckle Joint can also be used below the mechanical jars to improve the engagement of ill- positioned objects within the tubing or the location of Gas Lift Valve’s within Side Pocket Mandrel’s.
