Liner Lock Bead Wedge is used to help secure inground beaded liners and vinyl lock-in winter covers.
Liners and vinyl winter covers can sometimes fall out of the track for various reasons. This could be due to improper fit of the liner, corner stress, liner shrinkage, stressed or expanded liner tracks, water behind the liner, etc.
Liner Lock is a simple and effective product to help prevent this occurrence and secure the liner bead into the track. Liner Lock is also known as T-Lock, Bead Retainer, T-Bead or Bead Lock. Liner Lock is pressed directly into the thin void in the track directly above the bead and prevents the bead from coming out of the liner track. Easy to install and works with most beaded liner types.
Note: liner lock bead wedge is not for use with above ground pool liners.
