On this type of pool, the liner goes up and “overlaps” the pool wall with the excess material on the outside of the pool. Adjusting the liner wall height inside the pool is as easy as overlapping more or less of the vinyl to the outside of the pool wall. The swimming pool liner is held in place with clamps or the actual pool wall coping depending on the manufacturer.
Beaded swimming pool liners snap into a bead track that runs around the inside perimeter of above ground pools. Because the liner hangs inside the pool and does not overlap the wall, beaded liners offer patterns with borders at the top which tend to be more popular. Beaded liners must be ordered with the correct wall height since they do not have extra material like overlap liners do. Most wall heights are either 48- or 52-inch. Be sure to measure the height of your pool wall before selecting a beaded swimming pool liner. If you need to replace a beaded liner, one thing to consider is the size of the bead on your current liner. The bead size can vary from manufacturer to manufacturer. J-hook is a bead that allows the liner to hang off the pool wall without a bead track. This option allows you to choose a beaded style pattern if your pool wall is 48″ or 52″.
A stretchable swimming pool liner made to accommodate a “deep end” is called an expandable liner. These are made to fit above ground pools up to 72 inches “deep”. These are also known as stretch-to-fit liners.
