ABSTRACT:
A universal clamp for an adjustable post includes a split base clamp mounted on a stationary supporting stud. An elongated channel in the form of a yoke including a rigid extension protruding through the split base clamp slidably supports a pair of opposed jaws adapted to engage the post. The channel is enclosed within a covering sleeve. One jaw is fixed with respect to the sleeve. The remaining jaw is operably movable through a lever operator and interposed over-center toggle plate. Manipulation of the lever operator tensions the channel and extension. This tightens the split base clamp. It also engages complementary radial serrations surrounding the extension on one end of the sleeve and on the split base clamp. The jaws are compressively moved toward one another through the toggle plate and interposed sleeve to grasp the post and thereby fix its position relative to the mounting stud.
