ALETTE A Drop Seal Threshold Bar 1030mm Scissor-Type Seal 14mm Extension Support

Product Overview

The ALETTE A drop seal threshold bar (1030 mm with support) is used for sealing the gap between doors and thresholds in commercial and residential environments. It features an automatic adjustment system that lowers the seal to meet the floor when the door closes, and retracts upon opening, allowing smooth passage over carpets and uneven surfaces. Installers and facility managers utilize this system in projects aiming for improved acoustic, dust, and draft protection without compromising accessibility.

The distinguishing feature of this model is its scissor-type seal extension mechanism, capable of a maximum 14 mm deployment, far above typical threshold seals. This enables full gap closure on doors with large or irregular clearances, minimizing risk of air, noise, or pest infiltration in demanding sites. Its trim-to-fit capability (up to 150 mm from the opposite side of the activation button) offers flexibility for bulk installations or renovation scenarios where threshold lengths vary.
