A beam support yolk engages a structural beam and the support yolk rotationally engages the strut cap. A strut base includes a threaded receiver and a cavity, the cavity being positioned below the threaded receiver. The threaded portion of the strut includes the threaded receiver. The strut further provides a device for rotational advantage for rotating the strut and the strut cap for adjustment in vertical position of the support yolk relative to a support surface under the strut base.</p> |
