Abstract
A subterranean well tool which is manipulatable by a control mandrel between run-in and set positions within a wellbore having casing includes an assembly which provides a selectively operable lock to prevent premature activation of the assembly from the run-in position towards the set position until a predeterminable compressive load is carried through the well tool by the control mandrel to manipulate the assembly from a first initial position to an intermediate position and thereafter to a final extended position.
