The Blum AVENTOS HS lift mechanism A 20S1A00 is a stay-lift system for single-piece overhead cabinet fronts with a height of 350–525mm and a total front weight of 2–5kg. The front rises upward and stays open horizontally, giving full, unobstructed access to the cabinet interior.

AVENTOS HS is Blum’s up-and-over lift system. Unlike parallel-lift systems, the front swings upward and over the cabinet, making it well suited to wall units where the front needs to clear the worktop or appliances below.
