The key that solves height errors
The tear-off profile at the bottom of the pocket (solid wall version) is a smart system to solve possible mistakes that might happen on construction site. It allows to correct the difference in height between the finished floor level and the bottom of the counterframe, even when the work is finished (counterframe already installed and screed already poured).
By using this special key you simply need to “rip off” the bottom profile as if it was the ring-pull of a beer can.
