Abstract
A locking bracket is adapted to join together two metallic frame members forming an L-shaped joint, the members having channel shaped cross sections. The bracket includes (a) an L-shaped non-metallic body with legs formed for reception into the respective members to bridge the joint, (b) the legs having sections that taper in downward directions of reception into the members for interference interfit with shoulders defined by the members, (c) and the legs having ledges that face in upward directions opposite to fit closely under and forcibly engage shoulders on member flanges in response to completed reception of the legs into the members. Pins may be provided to positively hold the legs to the members, and at locations to prevent member relative pivoting.
