ALETTE A Drop Seal Bar 330 mm Scissor Action 14 mm Extension with Support Arms

Product Overview

The ALETTE A Drop Seal Bar 330 mm is a threshold sealing system designed to close the gap between the door bottom and floor, commonly used in residential and commercial interiors. Its automatic drop mechanism adjusts the seal to the floor surface as the door closes, while retraction during door opening prevents interference with carpets or flooring. Suited for installation on various swing door types, the unit measures 330 mm in length, 28 mm in height, and 30 mm in width with support arms.

The standout feature of this SKU is its scissor action seal extension, capable of deployment up to 14 mm. This mechanism ensures reliable sealing even when floor levels are uneven or gaps are wider than typical. Facility managers and contractors will find this variant particularly suitable for doors requiring robust acoustic or dust control measures in offices, hospitality, or healthcare environments.
