A waler assembly for floating docks and walkways includes an elongate metal extrusion for engaging the side of a series of adjoining float components. The extrusion includes a compartment for conformably receiving an elongate wedge. Connector rods join the extrusion and wedge to the float components. The extrusion carries an elongate strengthening plate that extends across the compartment of the extrusion. Each of the extrusion, wedge and strengthening plate includes a plurality of discrete segments that are aligned end to end. The joints between adjoining segments of the waler assembly are offset to provide improved structural integrity of the waler assembly and the floating dock or walkway.
