ABSTRACT:
An apparatus for setting the spacing of a free standing range relative to a floor includes a base component for contacting the floor, a threaded element, and a winding follower. The winding follower extends into the helical recess of the threaded element such that the winding follower travels progressively further along the helical recess of the threaded element. A blocking member engages the winding follower during travel of the winding follower along the helical recess of the threaded element to resist a disengagement movement.
