Abstract: The outer and inner side decks of a curved escalator are connected at its inner end to the balustrade, and includes a horizontal top panel which extends outwardly away from the balustrade, and outer vertical curved in plan side panel which extends downwardly from the outer edge of the top panel. These deck panels are secured to inner support components of the deck. The corner of the deck where the top and side panels meet is covered with a plastic trim molding which covers the screws fastening the side panel to the underlying supports, and which snaps onto catches which are hidden on the underside of the top panel. An attractive corner is thus formed free of unsightly screws, bolts, or other fasteners.
