Heavy duty Liner Lock will help keep your liner from slipping out of the coping.
The longer you own your swimming pool, the tendency over time is that your liner will pop out out of the track.
Liner Lock will basically "Lock" your liner in place between the swimming pool wall and pool coping.
When your liner is Locked, it will not become unseated or pull out of the tracking.
Commercial grade for problem pool liner installs.
One kit is enough to lock up to a 20 ft. x 40 ft. swimming pool. Also works on all sizes of above ground pools!
