With the Schnabl buried installation method plastering is not required thanks to the single and double concealed installation clip.
The integrated nib on the interior side of the clip enables the pipe to tense between the two clips for easier cable insertion. For single installation Schnabl has the USE, and here the hose must first be covered and then inserted with the clip into the drill hole. Here too, one clip is suitable for two clamping ranges, just like with the double buried clamp USD.
For double installation Schnabl has the USD, and here the hose must first be covered and then inserted with the clip into the drill hole. Two pipes are mounted at the same time with the USD without plastering and with just one borehole. And thanks to the integrated nib on the interior clip side, the pipe can be tensed for easier cable insertion.
For buried installation accurate holes are important. Schnabl has developed a special drill, namely the lance drill for hollow bricks. Drilling is done with a simple twisting movement – no percussion, and all the webs in the hollow brick are maintained. Tiles and glass can also be drilled without any problems and without anything breaking.
