Cardinal Pools qp-532 Liner Lock Corner Set 6 in Radius 4-piece

Product Description

The CARDINAL POOLS qp-532 is a four-piece set of Quaker-profile liner lock corners designed for above-ground swimming pool liner installation. Each corner piece features a 6-inch radius bend, matching the Quaker bead track profile used on compatible pool walls. These corners secure the liner bead at the top rail junction, keeping the liner seated and preventing pullout at the most stress-prone points of the pool perimeter. Pool service technicians and installers use this set when replacing or installing a beaded or J-hook liner in pools built with the Quaker track system.

This corner set is suited for residential above-ground pool liner replacement work. The four-corner configuration covers a standard rectangular or oval pool layout. Installers use these corners in conjunction with straight liner lock sections to complete a full perimeter lock. The 6-inch radius matches the corner geometry of pool walls using the Quaker liner lock track, making this set appropriate for pool liner changeouts where the original corners are cracked, missing, or no longer holding the liner bead securely.

Key Features

• Set of 4 corners covers all corner positions on a standard above-ground pool
• 6-inch radius matches Quaker-profile liner lock track geometry
• Liner lock design clamps the liner bead at the top rail, resisting pullout
• Quaker profile ensures fitment with compatible bead track systems

Compatibility

Designed as an OEM-style replacement for above-ground swimming pools using the Quaker liner lock bead track system with a 6-inch corner radius.

Installation Notes

Installation is typically performed by a pool service technician during a liner replacement. Drain or partially drain the pool before removing the existing liner and corner locks. Inspect the top rail and wall channel for damage before seating the new corners. Ensure the liner bead is fully seated in the lock channel at each corner before filling to prevent blowout under water pressure.
