The 21’ Mocha 52" Costa Uprights are essential structural components for 21’ round above-ground pools. Designed to support the pool wall and connect the top ledge to the bottom track, these 52” tall uprights align with standard pool wall heights and help maintain the pool’s shape and structural integrity. Their mocha finish offers a modern aesthetic that complements contemporary backyard designs and their heavy-duty construction is engineered for durability, weather resistance, and long-term performance.
