Different Types of Aboveground Pool Liners
Some liners are what we call overlap. This type is the most common and folds over the wall, draping down on the outside of the wall. The liner is held in place by plastic coping.
Beaded liners have a formed plastic bead at the top that hooks into a female receptor around the top of the pool wall. Beaded liners are sized exactly to the height of the wall.
J-Hook-V-Bead are liner types that have a thicker open flap top that inserts over the corrugated metal wall. It looks likes the plastic coping we use to hold an overlap liner over the metal wall except that, in this case, it is attached to the top of the liner. A J-bead liner has 2 plastic beads – One of these beads can be cut off, and the liner will turn into a regular Beaded liner.
