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.

[ What we claim is:] [1.] A spacing tool for setting frame members which have a width W and an inter-member spacing interval I, the spacing tool comprising:an elongated body having a longitudinal axis, and a first track and a second track which extend along said body and are parallel to said longitudinal axis;a cradle formed by a first head and a second head; anda shoulder formed by a third head,wherein each of said heads slidably engages said first track and said second track, and further wherein each of said heads further comprises:an indexing face for engaging the frame members, said indexing face being substantially normal to said longitudinal axis when said head is slidably engaged with said first track and said second track, andmeans for locking said head with respect to said elongated body,whereby said first head and said second head can be disposed along said elongated body in an opposed relationship to form said cradle, with said indexing face of said first head in a face-to-face relationship with said indexing face of said second head, and positioned at a separation width W therefrom, while said third head can be disposed on said elongated body such that it corresponds to a translation of one of said first head and said second head by the spacing interval I.
