Note: Table shows tooth system selection for cutting one piece of the profile. For cutting of more pieces of the profiles (bundle), you must think of the size of
the wall as double size of the wall of one profile (that means, size „S“ equates to 2×S). In table, there are tooth systems constant and variable.
