The Blum AVENTOS HF centre hinge set 20F78Z50A is the central pivot hinge for bi-fold overhead cabinet doors fitted to metal frame carcasses. Opening to 134°, it provides the central fold point for the AVENTOS HF door panel, ensuring precise alignment and long-term durability in aluminium-frame kitchen and furniture installations.

AVENTOS HF is Blum’s bi-fold lift system — the door folds in two sections as it opens upward, making it ideal for tall overhead cabinets where a single-piece door would require too much clearance. This hinge set is the unsprung, screw-on version for metal frame applications.
