The Invisidoor Hinge Kit allows a purpose-built bookcase to operate as a concealed door. It is suitable for secret rooms, studies, wine cellars, utility spaces and anywhere a doorway needs to be hidden within fitted joinery.
The pivot system can be configured to open inwards or outwards and can be fitted on either the left- or right-hand side. It supports a combined bookcase and contents weight of up to 300 lb (approximately 136 kg).
The kit includes heavy-duty powder-coated steel hinge plates, an adjustable support foot and the required fasteners. The pivot mechanism is designed to provide smooth, quiet movement while carrying the weight from beneath the bookcase.
This is a hardware kit for joiners, cabinetmakers and experienced installers constructing a bookcase door to suit a particular opening. Detailed instructions are provided, including guidance on building the bookcase, positioning the pivot plates and allowing sufficient operating clearance.
For an additional concealed opening mechanism, the kit can be paired with our Secret Book Pull, which releases the door latch when the book is pulled forward.
Please note: the bookcase, surrounding joinery and Secret Book Pull are not included.
