Abstract
Abstract A concrete and liner retainer coping for a pool and the like comprising an upper vertical wall having a top arcuate curved portion curving rearwardly in a direction away from the pool and formed with a vertically downwardly depending lip ending in a free edge thereof. A horizontal part extends rearwardly relative to the vertical wall and has at its free rear end an upwardly directed vertically oriented back lip. A connection portion integrally connects the horizontal portion to the vertical portion, and a lower vertical edge is joined to a front end of the horizontal part, the latter in cooperation with the connecting portion forming a mouth adapted to receive therein the liner.
