Abstract: The present invention relates to vinyl lined swimming pool copings and provides an aluminum sub-coping of the concrete receptor type in combination with a fully supported PVC snap-cap which is secured in place over what would otherwise be an exposed surface of the aluminum sub-coping, utilizing special locking grooves in the sub-coping. As well, the PVC snap-cap can be provided with a built-in bead cover and/or bead retainer. Using appropriate tooling, the aluminum sub-coping of the present invention can be shaped to permit it to be installed on curved shaped pools.
