Liner grip is used to fix liner to brick, limestone and timber walls that surround a pond. The female Grip Clip piece is bolted to the wall and the pond liner edge is simply "clipped" into place using the male section of the Grip Clip allowing for a perfectly professional finish to the pond. Great for fixing liner to existing ponds where capping is already in place. Will hold liner from 0.5mm thick to 1.14mm thick. Comes in 3m lengths only.
