ABSTRACT:
The present invention is a tool for spacing frame members having an elongated body which has a first and a second track. A cradle, formed by a first head and a second head, can be adjusted to accommodate a first frame member of width W, and a shoulder, formed by a third head, can be spaced apart from the cradle to engage a second frame member, separated from the first frame member by a spacing interval I. Each of the heads slidably engage the first track and the second track of the elongated body, and each have an indexing face which is substantially normal to the elongated body. The heads are lockable with respect to the first and second tracks. Preferably, the elongated body has a bubble level to aid in identifying when the body is horizontal. When a bubble level is employed, each head has a levelling surface, the levelling surfaces being co-planar, providing a discontinuous reference surface for levelling. Preferably, the elongated body is provided with indicia to indicate standard values for the spacing interval I. A fourth head may be provided, and the third head and the fourth head form a second cradle. The heads may be configured to be adjustably attachable to a pre-existing beam level, which then serves as the elongated body of a spacing tool, and therefore have utility in their own right.
