The 6” Radius 90° Corner Liner Retainer is engineered for precise use in vinyl liner inground pool construction. Designed to hold the liner bead firmly in place at tight-radius corners, this aluminum retainer ensures a secure fit and a smooth visual transition in curved sections. The powder-coated white finish offers durability and a clean finish, and it plays a critical role in reinforcing high-stress areas where liners are most prone to shifting.
