Automatic Drop-Down Door Seal CON ALETTE C.C.E. – 44 dB

Automatic Drop-Down Door Seal CON ALETTE C.C.E. is a concealed automatic seal designed for installation into the bottom edge of a door leaf. It closes the gap between the door and floor, helping to reduce the transmission of noise and smoke underneath the door.

When the door closes, the mechanism automatically lowers the seal towards the floor. When the door opens, it retracts back into the profile. CON ALETTE seals gaps of up to 14 mm, allowing a continuous floor surface without a conventional raised threshold.

The model features a C-profile seal providing a 44 dB noise protection rating. The mechanism has been tested for 200,000 opening and closing cycles, providing reliable long-term operation.

Available lengths are 430, 530, 630, 730, 830, 930, 1030 and 1130 mm. The profile can be shortened to the required length, making it suitable for different door leaf widths. Manufacturer — C.C.E., country of origin — Italy.
