How It Works - Pivot Mechanism

This is a standard butt hinge operating on a reliable pivot mechanism. It consists of two interlocking leaves joined by a central pin. One leaf mounts to the moving component (door or lid), the other to the fixed frame. The pin allows for a smooth and stable rotational movement, enabling reliable opening and closing. The SUS 304 stainless steel construction ensures consistent performance and resistance to rust and tarnish.
