Abstract: A decorative glass panel railing assembly includes a plurality of spaced apart vertical line posts, each joined to an anchor plate which is secured to a floor or deck surface. Each line post includes a pair of channels formed therein on opposing sides thereof, each channel including a pair of opposed detent grooves extending longitudinally therein. A bottom glazing rail extends between each pair of line posts, with each end secured in a channel of the respective line posts. A glazing insert is disposed in each post channel atop the bottom glazing rail, and is secured therein by opposed detent flanges which engage the detent grooves of the channel and lock therein. The bottom glazing rail and the glazing inserts are each provided with a pile lined glazing channel therein to receive the edge of a glass panel. A glazing sub-rail extends between the upper ends of the line posts, with a top rail snappingly engaged atop the glazing sub-rail.
