Abstract

A passenger conveyor system (20) includes a handrail assembly (30) having a guidance (40) for guiding a moving handrail (32). The example guidance includes an extrusion and presents a continuous, uninterrupted guiding surface (44) along which the handrail (32) travels. In a disclosed example, a single-piece extrusion (50) extends along an entire length of a balustrade (34). A disclosed example includes a first material forming a body of the guidance (40) and a second material (70) establishing the guiding surface (44).
