cod. ASDB


Solid and resistant, the acoustic seal by definition. Thanks to its wide three-cell seal, it has a 52dB acoustic certification by the IFT Rosenheim. This model is equipped with a plunger on both sides: a steel plunger adjustable with a screwdriver on the one side, a plastic plunger on the other. This double plunger system allows the maximum pressure on the floor for a great acoustic performance.
