Abstract An adjustable length strut having a unique locking device. An annular spring within a housing surrounds an actuator rod. An actuator member engages one end of the annular spring axially compressing it and causing radial bulging resulting in locking the rod in position relative to the housing. Numerous embodiments are disclosed which may replace gas springs in such applications as seat height adjusters, chair arm adjusters and seatback adjusters. An embodiment is disclosed employing a switch to activate and deactivate the actuator member.
