Abstract
A modular stretcher to which sheets of canvas may be secured with staples or like fasteners, includes elongated members having a substantially L-shaped cross section and brackets connecting the ends of the members. Each elongated member includes on its outer surface a longitudinally extending groove for supporting a fastener-receiving strip. The inner corner of each member includes a longitudinally extending channel for accommodating an edge of a bracket. The brackets are connected to the members by bolts passing through holes in the bracket and holes in the member. The stretcher may be further strengthened with a cross bracing arrangement connected to the elongated members.
