Swimming Pool Liner Clip on Cove Molding 25 - Pack for a 21-Foot-By-41-Foot Oval Pool

SmartLine Original Cove Molding is a 3" x 4", pre-formed cove molding made from chemically neutral, closed Ethafoam and is safe for use with all pool brands and liners. This lightweight cove molding comes in 48" sections that bend easily without breaking. Its unique plastic backing strip makes it easy to install, locking each section into your pool's bottom rail, allowing it to move as the pool wall expands and contracts.

Cove molding is needed to keep the weight of the water in the pool liner from causing it to balloon out under the bottom of the pool wall. Unlike sand or dirt, SmartLine Cove Molding cannot be washed out and will not hold moisture against metal components. Because SmartLine Cove Molding is made from high-density foam, it will not change shape or indent, making pool cleaning easier.

• Installs in minutes
• Flexible & lightweight
