Claim:
A device comprising: a center deck, the center deck being substantially planar; a first pair of spacing surfaces, the first pair of spacing surfaces being substantially planar and substantially parallel surfaces that extend from a bottom side of the center deck at a right angle thereto, and that extend substantially along a width of the center deck, and the first pair of spacing surfaces separated by a first distance along a length of the center deck that is fixed and selected to space studs; a second pair of spacing surfaces formed by opposing sides of a single, planar part that extend upward at a right angle from a center line of the center deck, the second pair of spacing surfaces extending substantially along the length of the center deck and separated by a second distance along the width of the center deck that is fixed and selected to space floorboards; and an adjustable spacer extending from the center deck that provides a range of user-selectable spacings from additional spacing surfaces.
