The finely engineered No 3230 concealed hinge consists of precision milled scissor-like arms which extend when pivoted, allowing a door or panel to swing open as much as 180 degrees. The hinge is completely invisible when the door is closed. Minimum door thickness required is 1 1/2”. The hinge measures 7 1/2″ x 2 7/8”. Unlike Soss concealed hinges, which are available in a limited number of finishes, the No 3230 can be finished in a wide variety of Nanz plated and patinated finishes.
