Abstract: A swimming pool sectional wall construction having connectors permitting quick assembly of wall components into a rigid, self-aligning structure. Panels comprising wall components have longitudinal flanges formed along each side edge defining an acute angle with the plane of each panel whereby flanges on adjacent panel edges diverge from each other. A connector, having a pair of opposed converging faces adapted to receive said diverging flanges, secures the adjacent panels in tight-fitting abutment.Novel copings seated on the wall top edge permits detachable securement of a post liner thereto.
