ALETTE A 530 mm Drop-Down Threshold Seal Adjustable Length Automatic Gasket

Product Overview

The ALETTE A 530 mm drop-down threshold seal is engineered for installation on the lower edge of doors in both residential and light commercial environments. Its primary function is to automatically seal the gap between the door and floor, maintaining energy efficiency and reducing dust, drafts, and noise penetration. The concealed retractable gasket adapts to floor surfaces and retracts when the door is opened, preventing interference with carpets or flooring.

ALETTE A 530 mm distinguishes itself by allowing the profile to be shortened by up to 150 mm on the side opposite the actuator button, which simplifies retrofitting on non-standard or smaller door leafs. This feature is particularly valuable to installers and OEM procurement managers who require on-site customization for mixed door sizes during renovation and maintenance projects.
