GLI Boulder Overlap Liner

Yes, this liner is specifically designed to accommodate wall heights ranging from 48 to 52 inches, so it will fit a 52-inch wall perfectly.

An overlap liner is designed to drape over the top of your pool wall and hang down the outside. You then secure it in place using coping strips, which hold the excess material firmly against the wall before you reinstall your top rails.

At 12 mil, this liner provides a standard level of durability suitable for typical seasonal use. While it is not the thickest option on the market, it is constructed from 100% virgin vinyl, which offers good resistance to seasonal wear and tear.

No, coping strips are generally sold separately. You will need to purchase them based on the specific top rail configuration of your pool to secure the overlap material properly.

The 20-year limited warranty typically covers manufacturing defects in the vinyl and the seams. It does not cover damage caused by improper installation, chemical imbalances, or physical punctures from sharp objects.
