Once the tiles are laid, simply turn the screws counterclockwise and remove the main anchor; you may need to hammer gently.

It is quite easy to fix or remove with the wrench to improve the speed of tile installation. Suitable for tile thickness from 3 mm to 16 mm, but can be used with tiles up to 18 mm thick.
