Abstract: A pool coping system comprises a plurality of straight and curvable pool coping pieces. Each piece bears an opposing flange and groove thereon, which are alignable with the flange and groove on adjacent coping pieces. The pieces are joined by the insertion of an h-shaped clip into the adjacent coping pieces. The pool coping pieces comprise outward and inward piece portions. On only the foldable coping piece, the inward portion bears at least one V-shaped notch therein, with a corresponding number of relief cuts disposed in the outward piece portion opposite the at least one notch. A somewhat coplanar wall and flange are carried on the outward and inward piece portions, respectively. The invention includes the h-shaped clip, having two parallely disposed and longitudinally extending planar members. One of these members is narrower than the other, and is joined to the wider member by a somewhat perpendicularly disposed clip wall.
