A nickel silver ring, which is just 0.8 mm thick, gives the highest tenon connection additional stability and durability.
Particularly in the high range, moisture and thermal expansion cause severe stresses on the clarinet corpus.
Although this nickel silver ring weighs only 1 gram, it has been designed to prevent excessive expansion or swelling of the grenadilla wood.
Surface cracks, changes in intonation, jamming of the barrel joint - this additional protective ring considerably reduces the risk of these problems occurring.
Of course, in the Silver Line clarinet range this protective ring is produced in solid silver.
