ALETTE A Drop-Down Threshold Seal 730mm Scissors Mechanism Adjustable Shortening

Product Overview

The ALETTE A drop-down threshold seal (length 730 mm) is used to effectively seal the gap between door and floor in commercial and residential interiors. It features a scissors-action mechanism that automatically adapts the seal to uneven flooring, minimizing drafts and noise. When the door is opened, the seal retracts to prevent obstruction, making it suitable for spaces with carpet or other soft floor coverings.

A distinct feature of this model is its ability to be shortened by up to 15 cm from the side opposite to the activation button, providing extra flexibility for installers working with non-standard door widths. This adjustability makes it particularly advantageous for bulk procurement, facility renovations, or OEM projects where custom-fit thresholds are often required.
