ALETTE A Drop Seal Threshold Strip 1830 mm Self-Adjusting for Wide Doors

Product Overview

The ALETTE A Drop Seal Threshold Strip (1830 mm) features a scissors-type actuated mechanism that seals the gap between the door and threshold, self-adjusting to variations in floor height. Commonly used in commercial and high-traffic residential door assemblies, it prevents drafts and maintains acoustic separation. The actuator retracts the seal during door opening, avoiding interference with carpets or floor coverings.

Its substantial 1830 mm length distinguishes this SKU, making it suitable for oversized or double-width doors, where standard seals are too short. This reduces procurement challenges for projects requiring non-standard door sizes and ensures seamless sealing capability. Facility managers and contractors handling large-format or custom-exit installations will find it particularly suitable for bulk or retrofit projects.
