Automatic Drop-Down Door Seal JNF IN.06.006 DOUBLE – 54 dB

JNF IN.06.006 DOUBLE Automatic Drop-Down Door Seal is a high-performance concealed door-bottom seal developed for applications requiring enhanced acoustic performance. The DOUBLE system uses two parallel seals to achieve acoustic performance of up to 54 dB Rw.

When the door closes, the mechanism automatically lowers the seals towards the floor, closing the gap underneath the door leaf. When the door opens, the seals retract back into the profile, allowing a continuous floor surface without a conventional raised threshold.

The JNF IN.06.006 DOUBLE has a profile size of 25 × 28 mm. The mechanism is reversible: the activation plunger can be removed and inverted to change the operating direction.

Standard lengths are 630, 730, 830, 930, 1030, 1130 and 1230 mm. It is an excellent solution for interior and technical door projects where acoustic performance and concealed door-bottom sealing are important.
