Abstract
A visual display rack includes an extension bar vertically slidable in a hollow standard. A one way clutch mechanism allows the bar to be raised but unless released, locks the bar against downward movement in order to support the load placed upon the bar. The clutch mechanism is released by a button inconspicuously located at the top of the bar. The entire clutch mechanism is carried by the extension bar. The standard is not in any manner altered for cooperation with the mechanism.
