An apparatus for leveling floors and the like has base structure with support structure affixed thereto and projecting upwardly therefrom. The support structure defines an open-sided, open-topped slot. Wedge structure is positionable in the slot throughout the length of the support structure and is adapted for attachment to the support structure in a plurality of vertical positions. The wedge structure forms an abutment surface for supporting, and raising, a structural member disposed in the slot. Connecting structure detachably connects the wedge structure and the structural member to the support structure. Independent and alternate attachment to and repositioning of the wedge structure and the structural member to the support structure effects vertical adjustment of the structural member. Structure is provided to pull the wedge structure through the slot.
