<p>A two-piece assembly one part of which is adjustably slidable relative to the other and into load-bearing position to hold a workpiece or structural assembly. The parts, which desirably may be of molded plastic, are formed with cooperative interlocking guide means, and their interfaces preferably include serrations disposed in inclined planes whereby the parts are anchored against slippage from a suitably adjusted work supporting relation. The range of take-up action is dependent on the ramp inclination of the base part upon which a normally shorter complementary part is movable into and automatically locked in work abutting position.</p> |
