A balustrade assembly includes a decking panel and a skirt panel that are attached to one another and to a balustrade support structure without fasteners. A positioning device included in the balustrade assembly varies the position of the skirt panel relative to moving steps in two directions by pushing against stationary components that are a part of or otherwise connected to a frame of a passenger conveyor. A balustrade support employed in the assembly reduces material and manufacturing costs and is adjustable to vary the height of a balustrade panel and handrails in a passenger conveyor.
