The 10' White Aluminum Bead Retainer holds standard bead liners including Above Ground Beaded Coping, Hang Beads, or Hanger Bead Steps. Use to replace your above ground pool liner and update to a beaded liner type. If your above ground pool is on a deck or structure and built up to the pools edge you can remove an old pool liner and install a new pool liner without having to disassemble the pool or deck in any way.
