Abstract
A lift includes a housing for rotatably receiving a hydraulic cylinder with a piston rod coupled to a generally cylindrical support tube. A low profile connecting head for supplying hydraulic fluid to the cylinder is rotatably mounted to the housing but captively held to the housing in the axial (longitudinal) direction. This allows the connecting head to be rotated during installation of the lift to a table leg for easy coupling to the pressurized source of hydraulic fluid.
