Abstract
A raceway frame for a curved modular wall panel is made of molded thermoplastic material in order to avoid the expense of secondary forming operations. The frame is generally of an I-shape and is molded in two T-shaped sections which are joined by, for example, ultrasonic welding at the contacting bases of the T-sections.
