ABSTRACT:
A stretcher bar frame for artists' backing material and kit to make same. Lengths of lumber rails of conveniently available standard sizes, such as 1".times.3" and 2".times.4", can be used with a plurality of molded corner bracket units, each having two channels sized to receive, and completely enclose the outer side walls of, the lumber rails. In a first embodiment, the corner brackets units have a bead region extending around their upper and outer perimeter. In other embodiments, separate bead members are provided, which can be cut to a desired length, for fixable attachment to the lumber rails to form a continuous bead region around the perimeter of the stretcher bar frame, such that when the backing material is stretched over the front of the stretcher bar, it rides on the outer perimeter bead, and not on the stretcher bar frame.
