Liner Lock Bead Wedge / Bead Retainer for Inground Pools

The Liner Lock Bead Wedge is a simple, effective solution designed to help secure inground beaded pool liners and beaded winter covers in the liner track. If your liner or winter cover has popped out of the track due to shrinkage, corner stress, water behind the liner, or minor fit issues, Liner Lock provides added holding power to keep the bead firmly in place.

This product is installed by pressing it directly into the narrow gap in the liner track above the bead, preventing the bead from lifting or slipping out of the track. Liner Lock works with most standard beaded liner profiles and is quick and easy to install—no special tools required.

Also commonly referred to as T-Lock, Bead Retainer, T-Bead, or Bead Lock, this product is intended for inground pool beaded liners and beaded winter covers only. It is not the same as liner lock used for above-ground overlap liners.

⚠️ Important Compatibility Notice:
This product will NOT work if the bead track itself is damaged. Before ordering or installing, inspect the liner track carefully to ensure there are no cracks, breaks, or missing sections. Track failure is most commonly found in resin or PVC bead tracks, which must be repaired or replaced before using Liner Lock.

Ordering Tip:
Measure and calculate the perimeter of your pool to determine how many feet of Liner Lock you need to order.
