Overlap or over the wall: An overlap liner is installed by overlapping the pool wall and is covered over by coping strips (plastic edging), which may also be covered by the pool rail system and pool ledge itself. In most cases, this liner is visible from the exterior of the pool. The liner is held in place by plastic coping strips. You should always replace these if your old ones are brittle and dry.

Beaded Liner: A beaded liner is installed by snapping it into a track or snapping it into a bead receiver channel. This channel may be plastic or metal and is usually covered over by the rail system and pool ledge. The bead receiver is only visible from the inside of the pool. This type of liner in most cases has a uniformed pattern at the water line.

Uni-Bead Liners: A Uni-bead liner is also referred to as “J hook “ liner. Uni-bead liners are installed by slipping the J hook over the top of the pool wall and hanging it straight and securely on the pool. The top rail system then secures the liner to the wall. They will also fit pools with bead receivers. Both Uni-bead and J hook liners are only visible from the inside of the pool. These liners help prevent slippage of the liner, and prevent that unsightly appearance of the liner from outside of the pool. Most pools can utilize the standard bead that is common in the industry.
