The elegant style and a strong steel wall make the Trinity the perfect choice for your yard. Designed for rugged durability and many years of family fun, this pool features a .46-mm steel wall that is hot dip galvanized with a combination of zinc and aluminum for the ultimate protection against corrosion. The injection-moulded resin joints, top caps, 1-in bottom rails, 7-in top rails, and 6-in uprights are impervious to water and chemical damage. Potent U.V. inhibitors embedded in the resin provide additional protection against the elements. A true round top rail adds a graceful look. Includes an overlap standard gauge liner, skimmer, filter system, and ladder. Backed by a 30-year limited warranty.
