Do I need Overlap or Beaded pool liner?

Overlap Pool Liners

Overlap liners are the most common. They literally overlap, or wrap-over the top of the pool wall. Plastic strips, called coping, then rest on top of the pool liner.

Beaded Pool Liners

Beaded liners hook into a track called bead receiver. The beaded edge of the pool liner hooks into a slotted lip on the bead receiver.
