The Invisible Hinge range is designed for use on doors up to 60Kg with 2 hinges and 70Kg with 3 hinges. The range is suitable for use on 30-minute fire doors. The hinges allow the door to be opened to a 180º angle. Made from a Zamak base, the hinges have movement on 7 fulcrums that use high tensile plastic bearings allowing for high resistance and long life. The hinge only requires a 21mm mortice on the frame side of the hinge, enabling it to be integrated into small spaces. There is no need to cut the architrave for the hinge to be mounted flush. The hinge is reversible if mounted in the centre of the door edge, improving efficiencies for door fabricators. The hinges are equipped with a three-way adjustment system that allows fine tuning of the door with any 3 mm Hex Spanner. Aluminium plated caps are available in a wide variety of finishes to conceal the fixings and improve aesthetics.
