GLI Boulder Unibead Liner

The Unibead design is a hybrid system that allows this liner to function as either a beaded or an overlap liner. It features a J-hook that hangs over the top of your pool wall, making it much easier to install than traditional overlap liners while providing the clean, finished look of a beaded liner.

Yes, this specific model is precision-engineered for 27-foot round above-ground pools with a 52-inch wall height. It is critical to confirm your pool's wall height before purchasing, as this liner is designed specifically for that dimension.

Yes, 100% virgin vinyl is superior because it contains no recycled materials, which can weaken the liner over time. This construction ensures better flexibility, resistance to chemical degradation, and overall longevity compared to liners made with filler materials.

The 20-year limited warranty primarily covers manufacturing defects, such as seam failures or material flaws that occur under normal use. It does not cover damage caused by improper installation, sharp objects, or chemical imbalances, so proper maintenance is still required to protect your investment.

You generally do not need specialized tools, but you will need a few standard items like a shop vacuum to help seat the liner against the walls and floor. Because it uses a J-hook system, the installation process is more straightforward than traditional methods, but having an extra pair of hands to help position the liner is highly recommended.
